FIG. 1 is a flow diagram illustrating a PSD file parsing method according to an exemplary embodiment.

Referring to fig. 1, a PSD file parsing method 10 includes:

in step S102, a PSD file obtained after labeling each layer according to a preset layer labeling rule is obtained.

And the layer marking rule is used for setting names and groups for each layer.

Without loss of generality, taking an advertisement graph as an example, the layer types in the PSD file corresponding to the advertisement graph may include: background map layer class, content information map layer class, montage map layer class, label map layer class and button map layer class. The content information layer class may include: commodity layer subclass, text and pattern layer subclass and icon (LOGO) layer subclass.

For some layers with associations, in order to facilitate the program to perform operations such as moving/scaling on the associated layers at the same time, the layers may be grouped to form different "layer groups" to represent the linkage relationship between the layers.

In some embodiments, the body content included according to the graph layer group may include, for example: a text pattern layer group, a commodity pattern layer group, an icon and picture layer group and a background picture layer group.

In some embodiments, the layer labeling rule may include (where n denotes a sequence number):

1) for a shape area layer which is superimposed on the screen content and can be filled with solid color, gradation, or pattern, the layer name can be labeled as "background n", and when there are a plurality of background layers, the layer names are labeled as "background 1", "background 2", "… …", and "background n" in this order.

2) For the product grade layer, the name of the layer is labeled as "product n", and when there are a plurality of product layers, the product is named "product 1", "product 2", "… …" and "product n" according to the importance of the product.

3) If a product graphic layer needs to be grouped with its necessary associated decorative graphic layer, the graphic layer group can be labeled as a "product graphic layer group"; the commodity picture layer group can not contain a text pattern layer and a background layer.

4) For the text and pattern layer, the name of the layer can be labeled as "text and pattern n", and when there are multiple text and pattern layers, the visual importance of the text and pattern can be labeled as "text and pattern 1", "text and pattern 2", "… …" and "text and pattern n", respectively; the degree of visual importance may depend on the font size, font weight, or prominent color.

5) The text pattern layers and associated layers may be grouped, and their group of layers may be labeled "text pattern layer group"; the pattern layer set can not contain a commodity layer and a background layer.

6) For the icon layer, the layer name can be labeled as "icon n", and when there are a plurality of background layers, the layer names are labeled as "icon 1", icon 2 ", … … and" icon n "in sequence; the icon layers can be associated into groups, and the layer groups can be labeled as 'icon layer groups'; the icon and graph layer set can not contain a text and graph layer, a commodity graph layer and a background graph layer.

7) For some shape region layers that are related to the content message layer or that are superimposed on the background and can only be filled in solid color or gradually, the layer name can be labeled as "mask n", one PSD can have 0 to multiple mask layers, and when there are multiple mask layers, the layer names are labeled as "mask 1", "mask 2", … … "and" mask n "in sequence.

8) For a pixel graphic layer associated with an independent non-subject document, its layer name can be labeled "tag n" (no associated document), or "tag n-document x" (associated document, where "document x" is the document on the tag); a PSD may have from 0 to multiple label layers.

9) For some button pixel layers that are intended to attract the user to click into, their layer names may be labeled "button n" (no associated text), or "button-text x" (associated text, where "text x" is the text on the button); a PSD may have 0 to multiple button layers.

The layer grouping rule in the layer labeling rule is shown in table 1 below.

TABLE 1

The layer labeling operation may be performed by manual labeling, for example. The PSD file after the layer marking is renamed for each layer, grouping information can be added to the layers according to the rules, and the layers with the linkage relation are grouped into one group.

For PSD files belonging to a series in design (i.e. designs with similar layer structure or similar design style), a "template set" may also be formed. Thus, in some embodiments, prior to performing step S104, the method 10 may further include: and grouping the PSD files into corresponding template groups according to a preset template group classification rule. The "template set" may include, for example: a fixed position template set and a common template set. The common template group has no special grouping limitation, and can be arbitrarily defined according to requirements in practical application. The "fixed location template set" grouping of classification rules may include: the PSD files are the same in size, the text pattern layer number and the layer name of each PSD file are the same, the commodity layer number and the layer name of each PSD file are the same, and the icon layer number and the layer name of each PSD file are the same.

In step S104, the labeled PSD file is analyzed according to the PSD file format to obtain file information of the PSD file.

The file information includes: basic information and layer information of each layer, wherein the layer information comprises: layer name, layer attribute information, and grouping information.

The developer document of Adobe Photoshop provides a specification of PSD file format, which includes the content structure of the PSD file, the information content contained in each piece of content, and the number of binary bytes that each piece of information needs to read. According to the file format, the marked PSD file can be analyzed to obtain the file information of the PSD file.

The file information may include, for example, basic information of the PSD file and layer information of each layer.

The basic information of the PSD file may include, for example: canvas size (e.g., height and width), color mode, number of channels, etc.

The layer information of each layer may include, for example: layer name, layer attribute information, and grouping information.

Wherein the layer attribute information may further include: the position, the size, the picture layer picture, the transparency, the visibility, the mixed mode, the picture layer style and the like of the picture layer. For the pattern layer, the attribute information may further include: text content, text color, text weight, text space, text line height, font style, case locking, text change matrix, and the like.

The grouping information may include a grouping name and a position of each layer in the group, etc.

In order to keep the PSD file having rendering effect consistent with Photoshop when displayed on the browser, it is further required to convert some layer attributes of the layers in the PSD file into a data format corresponding to CSS (Cascading Style Sheets) suitable for the browser through certain calculation and rules. CSS is a style sheet language used to describe the presentation of HTML documents. CSS describes the problem of how elements on a screen, paper, audio, etc. medium should be rendered.

Therefore, in some embodiments, before performing step S106, the method 10 may further include: and converting the layer attribute information of each text and pattern layer in the file information of the PSD file into corresponding CSS attribute information. Table 2 shows a conversion comparison table between PSD layer attribute information and CSS attribute information:

TABLE 2

In step S106, the file information is constructed as the structured data of the PSD file according to the grouping information of each layer.

The structured data may include: basic information and layer tree information. The basic information may be the basic information included in the file information. The layer tree information is a data structure reconstructed according to the grouping information of each layer and taking the layer group as a unit. In each graph layer group, related information of each graph layer, such as a graph layer name, graph layer attribute information and the like, is sequentially included, so that structured data about the PSD file is formed.

The image content of the background layer of the PSD file may be outside the range of the size of the PSD file canvas, or smaller than the size of the canvas. In order to make the background layer image consistent with the canvas size, the background layer image needs to be cropped or insufficient.

Thus, in some embodiments, prior to performing step S108, method 10 may further include: and processing each layer belonging to the background group in the PSD file so as to enable the size of each layer to be suitable for the size of a canvas of the PSD file, and updating the processed data of each layer into structured data.

For the background layer image to be cropped, the range of cropping, i.e., the start position and the cropping size, needs to be determined first. Determining the cropping range requires comparing the position and size relationship between the background layer image and the canvas, and specifically includes the following four conditions:

1) the width or height of the background layer image is smaller than that of the canvas size, and the image part of the background layer image exceeds the canvas range;

2) the width and the height of the background layer image are both smaller than those of the canvas size, and the image is within the canvas range and has no excess part;

3) the width or height of the background layer image is larger than that of the canvas size, and the image part of the background layer image exceeds the canvas range;

4) the width and height of the background layer image are both larger than the width and height of the canvas size, and the image of the background layer image completely exceeds the canvas range.

After the cutting range is calculated according to the four conditions, the part overlapped with the canvas can be cut. After the image is cut, if the width and the height of the image are smaller than the size of the canvas, empty pixels need to be complemented, and the size of the image is ensured to be consistent with the size of the canvas.

In step S108, structured data of the PSD file is acquired.

And reading out the structured data of the PSD file so that the PSD file can be displayed and edited in a browser or intelligent terminal equipment. The structured data can be reduced by more than 50% compared to the PSD format file, for example, the size of the source PSD format file is 600KB, and after being converted into the structured data, the size is only 250 KB.

According to the PSD file analysis method provided by the embodiment of the invention, the PSD file subjected to layer labeling according to the standard layer labeling rule is directly analyzed to obtain the special attributes such as basic information, corresponding information of layers, mixed patterns and the like according to the PSD file format; and according to the labeled layer grouping information, structured data containing a layer tree structure is constructed. The structured data can enable the PSD file to be displayed and edited in a browser or intelligent terminal equipment, and meanwhile, the storage space is greatly reduced, and online storage is facilitated.

It should be clearly understood that the present disclosure describes how to make and use particular examples, but the principles of the present disclosure are not limited to any details of these examples. Rather, these principles can be applied to many other embodiments based on the teachings of the present disclosure.

FIG. 2 is a flow diagram illustrating another PSD file parsing method according to an example embodiment.

Referring to fig. 2, the PSD file parsing method 20 includes:

in step S202, a PSD file obtained after labeling each layer according to a preset layer labeling rule is obtained.

And the layer marking rule is used for setting names and groups for each layer.

Without loss of generality, taking an advertisement graph as an example, the layer types in the PSD file corresponding to the advertisement graph may include: background map layer class, content information map layer class, montage map layer class, label map layer class and button map layer class. The content information layer class may include: commodity layer subclass, text and pattern layer subclass and icon (LOGO) layer subclass.

For some layers with associations, in order to facilitate the program to perform operations such as moving/scaling on the associated layers at the same time, the layers may be grouped to form different "layer groups" to represent the linkage relationship between the layers.

In some embodiments, the body content included according to the graph layer group may include, for example: a text pattern layer group, a commodity pattern layer group, an icon and picture layer group and a background picture layer group.

The specific layer labeling rule may refer to the layer labeling rule in the method 10, and is not described herein again.

The layer labeling operation can be performed by manual labeling, for example. The PSD file after the layer marking is renamed for each layer, grouping information can be added to the layers according to the rules, and the layers with the linkage relation are grouped into one group.

For PSD files belonging to a series in design (i.e. designs with similar layer structure or similar design style), a "template set" may also be formed. Thus, in some embodiments, prior to performing step S204, the method 20 may further include: and grouping the PSD files into corresponding template groups according to a preset template group classification rule. The "template set" may include, for example: a fixed position template set and a common template set. The common template group has no special grouping limitation, and can be arbitrarily defined according to requirements in practical application. The "fixed location template set" grouping of classification rules may include: the PSD files are the same in size, the text pattern layer number and the layer name of each PSD file are the same, the commodity layer number and the layer name of each PSD file are the same, and the icon layer number and the layer name of each PSD file are the same.

In step S204, the labeled PSD file is analyzed according to the PSD file format to obtain file information of the PSD file.

The file information includes: basic information and layer information of each layer, wherein the layer information comprises: layer name, layer attribute information, and grouping information.

The developer document of Adobe Photoshop provides a specification of PSD file format, which includes the content structure of the PSD file, the information content contained in each piece of content, and the number of binary bytes that each piece of information needs to read. According to the file format, the marked PSD file can be analyzed to obtain the file information of the PSD file.

The file information may include, for example, basic information of the PSD file and layer information of each layer.

The basic information of the PSD file may include, for example: canvas size (e.g., height and width), color mode, number of channels, etc.

The layer information of each layer may include, for example: layer name, layer attribute information, and grouping information.

Wherein the layer attribute information may further include: the position, the size, the picture layer picture, the transparency, the visibility, the mixed mode, the picture layer style and the like of the picture layer. For the pattern layer, the attribute information may further include: text content, text color, text weight, text space, text line height, font style, case locking, text change matrix, and the like.

The grouping information may include a grouping name and a position of each layer in the group, etc.

In order to keep the PSD file having rendering effect consistent with Photoshop when displayed on the browser, it is further required to convert some layer attributes of the layers in the PSD file into a data format corresponding to CSS (Cascading Style Sheets) suitable for the browser through certain calculation and rules. CSS is a style sheet language used to describe the presentation of HTML documents. CSS describes the problem of how elements on a screen, paper, audio, etc. medium should be rendered.

Therefore, in some embodiments, before performing step S206, the method 20 may further include: and converting the layer attribute information of each text and pattern layer in the file information of the PSD file into corresponding CSS attribute information. The conversion rule between the PSD layer attribute information and the CSS attribute information may refer to the conversion rule in method 10, and is not described herein again.

In step S206, it is determined whether the layer name and the grouping information of each layer are correct according to the layer labeling rule, and if so, the process goes to step S208.

Before the structured data is constructed, whether the layer names and grouping information of all layers are correct or not is checked according to the layer marking rule, and if the layer names and the grouping information are correct, the following operation of constructing the structured data is carried out.

If not, for example, manual labeling may be performed again, and step S202 is re-entered, which is not limited to this.

In step S208, the file information is constructed as the structured data of the PSD file according to the grouping information of each layer.

The structured data may include: basic information and layer tree information. The basic information may be the basic information included in the file information. The layer tree information is a data structure reconstructed according to the grouping information of each layer and taking the layer group as a unit. In each graph layer group, related information of each graph layer, such as a graph layer name, graph layer attribute information and the like, is sequentially included, so that structured data about the PSD file is formed.

The image content of the background layer of the PSD file may be outside the range of the size of the PSD file canvas, or smaller than the size of the canvas. In order to make the background layer image consistent with the canvas size, the background layer image needs to be cropped or insufficient.

Thus, in some embodiments, prior to performing step S210, the method 20 may further include: and processing each layer belonging to the background group in the PSD file so as to enable the size of each layer to be suitable for the size of a canvas of the PSD file, and updating the processed data of each layer into structured data. For the specific clipping and complementing operations, refer to method 10, and are not described again.

In step S210, structured data of the PSD file is acquired.

And reading out the structured data of the PSD file so that the PSD file can be displayed and edited in a browser or intelligent terminal equipment. The structured data can be reduced by more than 50% compared to the PSD format file, for example, the size of the source PSD format file is 600KB, and after being converted into the structured data, the size is only 250 KB.

Those skilled in the art will appreciate that all or part of the steps implementing the above embodiments are implemented as computer programs executed by a CPU. The computer program, when executed by the CPU, performs the functions defined by the method provided by the present invention. The program may be stored in a computer readable storage medium, which may be a read-only memory, a magnetic or optical disk, or the like.
