Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

In view of the foregoing problems, exemplary embodiments of the present disclosure first provide a method for processing picture material. The method can be applied to terminal equipment, and can be used for processing the acquired initial picture data to generate a plurality of picture materials with different sizes. The terminal device may be a computer, a smart phone, a tablet computer, and the like, which is not limited in this disclosure.

Fig. 1 shows a flow of the present exemplary embodiment, which may include the following steps S110 to S140:

and S110, acquiring initial picture data.

The initial picture data may generally include basic information of the picture data, layer information, such as a layer name, layer attributes, grouping information of the layer, and the like, and the layer attributes may include a position, a size, a layer picture, layer characters, a transparency, a layer style, a mixed mode, and the like of the layer; the grouping information of the layers can be used to indicate which layer group the layers belong to, and information such as the number of layers of the layer group, the layer size, and the like. In terms of data Format, the initial picture data may be picture data in a PSD (photo Document Format) Format, or may also be picture data in a TIFF (Tag Image File Format) Format, which is not specifically limited in this exemplary embodiment.

In the present exemplary embodiment, the initial picture data may be picture data generated by an artist, or may be picture data acquired by other means, such as picture data acquired from a network resource or a public picture set. After obtaining the initial picture data, the user may import the initial picture data into the terminal device or a picture application running on the terminal device for processing.

To facilitate processing of the initial picture data, in an optional implementation, after the initial picture data is acquired, the initial picture data may be converted into JSON (JSON Object Notation) format data. By the method, the initial picture data can be converted into a lightweight data exchange format, so that data reading and analysis are facilitated, and the data transmission efficiency is improved.

And S120, analyzing the initial picture data, and determining main drawing board data of the initial picture data according to the layer structure information obtained through analysis.

The layer structure information may include layer information of each layer and layer grouping information of each layer in the initial picture data, for example, the layer structure information may include picture elements of each layer, layer names of layers, layer attributes, groups to which layers belong, attribute information of the groups, and the like; the main drawing board is a first drawing board generated by default on a page, and only one main drawing board is used for presenting main content for initial picture data; the main drawing board data may include picture data included in the main drawing board, and may include, for example, layers included in the main drawing board and information such as picture elements and layer attributes of each layer. In the present exemplary embodiment, the picture elements of each layer may include pictures, texts, tables, and the like.

After the initial picture data is obtained, layer structure analysis can be performed on the initial picture data, and main drawing board data of the initial picture is determined according to layer structure information obtained after analysis. For example, layer structure analysis may be performed on the initial picture data, which layers are included in the initial picture data and the layer group to which each layer belongs are determined, and picture data corresponding to the layer group with the largest number of layers is determined as main drawing board data.

In an alternative embodiment, the main palette data of the initial picture data may be determined by the following method:

determining whether the initial picture data comprises one or more layer groups and whether each layer group comprises one or more layers according to the layer information of each layer and the layer group information of each layer;

when the initial picture data is determined to comprise one or more layer groups and each layer group comprises one or more layers, determining the picture data of a first layer group in the initial picture data as main drawing board data;

when the initial picture data is determined to comprise one or more layers and each layer does not belong to any layer group, determining the picture data of the one or more layers as main drawing board data.

Specifically, when it is determined that the initial picture data includes one or more layer groups according to layer structure information obtained after the initial picture data is analyzed, that is, layer information of each layer and layer group information of each layer, and each layer group includes one or more layers, that is, the data structure of the initial picture data conforms to: when the initial picture data-layer grouping-layer are generated, determining the picture data of the first layer grouping in the initial picture data as main drawing board data; when it is determined that the initial picture data includes one or more layers according to the layer structure information obtained after the initial picture is analyzed, and each layer does not belong to any layer group, that is, the data structure of the initial picture data conforms to: when the picture data-layer is initialized, the picture data of the one or more layers may be determined as main drawing board data.

In addition, in an optional implementation manner, when the initial picture data includes a plurality of layer groups, there may be some layer groups that include layer information of one or more layers, and other layer groups that do not have layer information are empty layer groups, and at this time, in the layer group with layer information, the picture data of the first layer group with layer information may be determined as the main drawing board data according to the order of each layer group. The layer grouping sequence may be a default layer grouping sequence when the initial picture data is generated, or may be a grouping sequence labeled by a manufacturer when the initial picture data is generated.

By the method, the main drawing board data used for generating the multi-size pictures can be extracted from the initial picture data, the picture data volume can be reduced, and the data processing efficiency is improved.

Further, in an optional implementation, after obtaining the main drawing board data of the initial picture data, the main drawing board data may be converted into Base64 (binary data is represented based on 64 printable characters), and an acquisition link of the Base64 format data is generated, for example, the acquisition link may be a CDN (Content Delivery Network) link. Compared with the main drawing board data, the data in the Base64 format is a data format for representing binary data based on 64 printable characters, and is more beneficial to storage of the main drawing board data; a CDN link is a link generated based on a content delivery network.

Step S130, in response to the selection operation of the plurality of picture material templates with different sizes, creating a drawing board area with the same size as each picture material template.

The picture material template can be a template file which is generated in advance and used for generating picture materials with different sizes, and can be manufactured and generated by art workers according to actual requirements. In this exemplary embodiment, each picture material template may include one or more layers, and each layer may be used to display a specific picture element, such as a picture, a text, a table, and the like.

The user can select the picture material templates with different sizes through the terminal device, and the terminal device can respond to the selection operation of the plurality of picture material templates with different sizes to create the drawing board area with the same size as each picture material template. For example, when a user enters a picture processing interface as shown in fig. 2 through a picture application installed on a terminal device, etc., any one or more picture material templates may be clicked to create a drawing board area corresponding to each picture material template.

When the drawing board area the same as the size of each picture material template is created, the drawing board size can be set according to the size of the corresponding picture material template to obtain the drawing board area the same as the size of the picture material template. Specifically, in an alternative embodiment, the size of each picture material template may be determined by the following method, and the drawing board area is created according to the size of each picture material template:

determining whether the picture material template has a custom layer;

when the picture material template has a self-defined layer, determining the size of the self-defined layer as a target size;

when the picture material template does not have the self-defined layer, determining the maximum size of each layer in the picture material template as a target size;

and setting the size of the drawing board area corresponding to the picture material template as a target size.

The self-defined layer can be a layer preset or appointed by a manufacturer in the picture material template, and the self-defined layer has a fixed size; the target size refers to the size of the drawing board of the picture material template, such as length, width and the like, and is generally a fixed size.

In this exemplary embodiment, the terminal device may obtain layer information of the picture material template, and determine whether the picture material template has a custom layer according to the layer information, and when the picture material template has the custom layer, the size of the custom layer may be determined as a target size, otherwise, when the picture material template does not have the custom layer, the maximum size of each layer in the picture material template may be determined as the target size. Therefore, when the drawing board area corresponding to the picture material template is created, the size of the drawing board area can be set to be the target size.

By the method, the plurality of drawing board areas can be created at one time, each drawing board area is the same as the corresponding picture material template in size, and the operation is simple, convenient and quick.

And S140, synthesizing the main drawing board data to a drawing board area corresponding to each picture material template to generate a plurality of target pictures with the same picture size as the corresponding picture material template.

Specifically, each layer in the main drawing board data, such as a picture layer, a text layer, a table layer, and the like, may be synthesized to the drawing board area corresponding to each picture material template, so as to generate a plurality of target pictures having the same picture size as the corresponding picture material template. Therefore, target pictures with different sizes related to initial picture data can be generated, rapid generation of the pictures with multiple sizes is achieved, time for manually making the picture materials is greatly shortened, and the production efficiency of the picture materials is improved.

Since the main drawing board data can be stored through the acquisition link, in an optional implementation manner, before the main drawing board data is synthesized to the drawing board area corresponding to each picture material template, the main drawing board data can be acquired through the acquisition link. In this way, the terminal device can acquire the main drawing board data through the acquisition link without storing the main drawing board data to the local, so that the memory resource of the terminal device can be saved.

Specifically, in an alternative embodiment, referring to fig. 3, step S140 may be implemented by the following steps S310 to S320:

and S310, determining the target position and/or the target size of the picture element in the main drawing board data in the drawing board area corresponding to the picture material template according to the drawing board information in the main drawing board data and the area information of the picture material template.

The drawing board information in the main drawing board data may include size information of the main drawing board, position information and/or size information of picture elements in each layer. The size information of the main drawing board may be the width, the height, and the like of the main drawing board, the position information of the picture element in each layer may be the distance from the edge of the corresponding layer to the picture element in the layer, and the size information may be the size of the picture element in the layer, and the like. The area information may be position information and/or size information of a drawing board area corresponding to the picture material template, or position information and/or size information of an effective area in the drawing board area corresponding to the picture material template, and the like, and the effective area may be an area in the drawing board area for displaying main drawing board data, such as picture elements or text elements, and particularly, all the drawing board areas may also be set as effective areas thereof. The following tables 1 and 2 respectively show examples of the palette information of the main palette data and the area information of the picture material template, as follows:

TABLE 1

Drawing board information	Description of the invention
		Main drawing board _ width	Width of main drawing board
Main palette _ height	Height of main drawing board
		Main drawing board layer _ width	Width of picture layer in main drawing board
Main drawing board layer _ height	Height of picture layer in main drawing board
		Main drawing board layer _ left	Distance between picture element of layer in main drawing board and left side of layer
Main drawing board layer _ right	Distance between picture element of layer in main drawing board and right side of layer
		Main drawing board layer _ top	Distance between picture element of layer in main drawing board and top of layer
Main drawing board layer _ bottom	Distance between picture element of layer in main drawing board and bottom of layer

The main drawing board layer may be a target layer in each layer of the main drawing board data, that is, a layer currently processed. The drawing board information in the main drawing board data can be obtained by analyzing the main drawing board data. For example, the main drawing board data may be saved by variable mainBoard, and when the drawing board information is acquired, the width and height of the main drawing board may be taken out from the mainBoard and saved by variable width and height, respectively. The position information and/or the size information of the drawing board area corresponding to the picture material template can be obtained by traversing the variable tempsparedata for storing the picture material template data. Specifically, some position data of the main drawing board layer may also be calculated according to the position data of the main drawing board and the layers in the main drawing board, for example, a distance between a picture element in the main drawing board layer and the right edge of the layer — a distance between the picture element and the left edge of the layer — a width of the main drawing board layer; the distance from the picture element in the main drawing board layer to the bottom edge of the layer is main drawing board layer _ bottom ═ the height of the main drawing board-the distance from the picture element to the top edge of the layer-the height of the main drawing board layer.

After the main drawing board data and the picture material template are obtained, the target position and/or the target size of the picture elements of each layer in the main drawing board data in the drawing board area corresponding to the picture material template can be calculated according to the drawing board information in the main drawing board data and the area information of the picture material template. For example, the scaling of the picture element in the drawing board region corresponding to the picture material template and the position of the picture element in the drawing board region may be calculated according to the position information and the size information of the picture element in any layer of the main drawing board data, so as to obtain the target position and the target size of the picture element in the drawing board region corresponding to the picture material template.

Specifically, in an optional implementation manner, the target position and/or the target size of the picture element in the main drawing board data in the drawing board area corresponding to the drawing board material template may be determined by the following method:

calculating the target position and/or the target size of the picture element in the main drawing board data in the drawing board area corresponding to the picture material template by adopting a preset rule;

wherein the preset rules include any one or more of:

calculating the width proportion and the height proportion of the main drawing board and the drawing board area, and setting the width of each layer in the main drawing board data as the width of the drawing board area when the width proportion is larger than the height proportion; or when the width proportion is not larger than the height proportion, setting the height of each layer in the main drawing board data as the height of the drawing board area;

and determining a minimum distance value from a picture element in any layer in the main drawing board data to any layer edge in a preset direction, so as to set the coordinate value of the picture element in the preset direction as the minimum distance value.

When a target picture is generated, the width proportion and the height proportion of the main drawing board and the drawing board area can be calculated, and according to the size relation between the width proportion and the height proportion, when the width proportion is larger than the height proportion, the widths of all layers in the main drawing board data are set as the widths of the drawing board area, so that the scaling of all layers in the main drawing board data in the width direction is realized; correspondingly, when the width proportion is not larger than the height proportion, the heights of all layers in the main drawing board data are set to be the heights of the drawing board areas, and scaling of all layers in the main drawing board data in the height direction is achieved. By the method, the direction, namely the width direction or the height direction, of the main drawing board relative to the drawing board area can be determined to be the largest, so that the attribute value in the direction with the largest change amplitude is set as the attribute value corresponding to the drawing board area, the size of the main drawing board can be scaled to the size meeting the size requirement of the drawing board area at one time, and the possibility that the main drawing board exceeds the drawing board area in a certain direction in the drawing board area is avoided.

Furthermore, the coordinate value of the picture element in the preset direction may be set as the minimum distance value according to the minimum distance value from the picture element, such as a picture element, a text element, a table element, and the like in any layer of the main drawing board data to the edge of any layer in the preset direction. The preset direction may be a left-right direction or an up-down direction of the drawing board area relative to a user of the terminal device. For example, in the left-right direction, according to a distance from a picture element in any layer in the main drawing board data to the left and right edges of the layer, that is, a main drawing board layer _ left and a main drawing board layer _ right, when the main drawing board layer _ left < the main drawing board layer _ right, a coordinate value of the picture element in the main drawing board layer in the direction is set to a value of the main drawing board layer _ left; and when the main drawing board layer _ left is larger than or equal to the main drawing board layer _ right, setting the coordinate value of the picture element in the main drawing board layer in the direction as the value of the main drawing board layer _ right. For another example, in the up-down direction, according to a distance between a picture element in any layer of the main drawing board data and the upper and lower edges of the layer, that is, a main drawing board layer _ top and a main drawing board layer _ bottom, when the main drawing board layer _ top > the main drawing board layer _ bottom, a coordinate value of the picture element in the main drawing board layer in the direction is set as a value of the main drawing board layer _ bottom; and when the main drawing board layer _ top is not more than the main drawing board layer _ bottom, setting the coordinate value of the picture element in the main drawing board layer in the direction as the value of the main drawing board layer _ top.

Further, in an optional implementation manner, after determining a target position and/or a target size of a picture element in the main drawing board data in a drawing board area corresponding to the picture material template, the position parameter and/or the size parameter of the picture element may be displayed in a display screen of the terminal device. Referring to table 3 below, an example of one location parameter and size parameter in the present exemplary embodiment is shown, as follows:

TABLE 3

In an alternative embodiment, the main palette layer _ right and the main palette layer _ bottom may also be obtained by other methods, for example: the main drawing board layer _ right is the width of the drawing board area, the layer width of the layer in the main drawing board data and the distance between the picture element in the layer in the main drawing board data and the right edge of the layer; the height of the main drawing board layer _ bottom is the height of the drawing board area, the layer height of the layer in the main drawing board data, and the distance between the picture element in the layer in the main drawing board data and the bottom edge of the layer.

By the method, the user can determine the size, the position and the like of each picture element displayed in the picture board area according to the displayed size parameters, so that whether the size parameters, the position parameters and the like of the picture elements need to be adjusted can be further determined.

And step S320, synthesizing picture elements in the main drawing board data into the drawing board area according to the target position and/or the target size so as to generate a target picture with the same picture size as the picture material template.

For example, the positions of the picture elements may be set according to the position information of the picture elements in the main drawing board data in the drawing board area, such as the distance between the picture elements and the left edge of the drawing board area, so as to synthesize the picture elements to the drawing board area, thereby generating a target picture with the same picture size as the picture material template.

Further, when generating the target picture, in an optional embodiment, the following method may be further performed:

and adjusting the position and/or size of the target picture in response to the adjustment operation on the position and/or size of the target picture.

For example, referring to fig. 4, the user may input a location or size parameter for the modified area in the picture processing interface to set the location or size of the target picture in the palette area. By the method, after the target picture is generated, the user can further finely adjust the position or the size of the target picture, and the display effect of the target picture is optimized.

Fig. 5 shows another processing flow of the picture material in the present exemplary embodiment, as shown, the following steps S510 to S590 may be included:

in step S510, initial picture data is acquired.

Specifically, the initial picture data may be picture data generated by an artist, or may be picture data acquired by other means, such as a public data set or other network resources.

Step S520, parsing the initial picture data, and converting the parsed data into JSON format data.

Compared with the initial picture data, the JSON format data has smaller data size and is easier to read and store.

Step S530, converting the main drawing board data of the initial picture data into Base64 format data, and uploading the Base64 format data to a server to generate a CDN link.

After the CDN link is generated, the terminal device can obtain the main drawing board data through the CDN link without storing the main drawing board data to the local, so that the memory resource of the terminal device is saved.

And step S540, creating a main drawing board according to the main drawing board data.

For example, the user may select to open the main drawing board data in the picture processing interface to trigger the display of the main drawing board, and at this time, the size of the main drawing board displayed in the picture processing interface may be the same as the size of the main drawing board in the initial picture data.

In step S550, in response to a selection operation on picture material templates having different sizes, a drawing board area having the same size as each picture material template is created.

For example, when a user selects a plurality of picture material templates through a terminal device, the terminal device may create drawing board areas through Canvas, and the size of each drawing board area is the same as that of the corresponding picture material template.

Step S560, calculating the target position and/or target size of the picture element in the main drawing board data in the drawing board area corresponding to the picture material template according to a preset rule;

and step S570, synthesizing picture elements in the main drawing board data into the drawing board area according to the target position and/or the target size so as to generate a target picture with the same picture size as the picture material template.

In step S580, in response to the adjustment operation on the position and/or size of the target picture, the position and/or size of the target picture is adjusted.

For example, the user may set a position parameter or a size parameter of any picture element in the target picture in the picture processing interface to adjust the position or the size of the target picture.

In step S590, a target picture is derived.

When the user selects to export the target picture, all the target pictures with different sizes can be exported at one time, and the rapid conversion from the initial picture data to the target pictures with various sizes is realized.

In summary, according to the method for processing a picture material in the exemplary embodiment, the obtained initial picture data may be analyzed, main drawing board data of the initial picture data is determined according to the layer structure information obtained through the analysis, a drawing board region having the same size as that of each picture material template is created in response to a selection operation on a plurality of picture material templates having different sizes, and the main drawing board data is synthesized to the drawing board region corresponding to each picture material template to generate a plurality of target pictures having the same picture size as that of the corresponding picture material template. On one hand, the exemplary embodiment synthesizes the main drawing board data into the drawing board area corresponding to each picture material template, so that target pictures with different sizes can be generated, and target pictures with various sizes do not need to be manufactured manually, thereby improving the output efficiency of picture resources, and saving the cost in the aspects of manpower, resources and the like; on the other hand, by analyzing the layer structure information of the initial picture data, the main drawing board data can be extracted from the initial picture data, so that only the main drawing board data needs to be processed when the target picture is synthesized, and the data processing efficiency is improved.
