Description

Technical Field

[0001] The present invention relates to the technical field of image processing, and more specifically, to a method and storage medium for generating PSD files without relying on PS software. Background Art

[0002] Currently, to generate (or save) an Adobe Photoshop format file, the conventional method is to purchase Adobe Photoshop software (abbreviated as PS software) and install it on a computer, then use Adobe Photoshop to create a new PSD format file, edit (add content), and finally save the file. Therefore, on a computer without the corresponding software installed, it is impossible to generate a PSD format file, which is greatly limited by the usage environment. Moreover, in some computer environments with relatively low performance configurations, even if the corresponding software is installed, it is difficult to run smoothly, causing inconvenience to operations. Summary of the Invention

[0003] The present invention provides a method and storage medium for generating PSD files without relying on PS software, aiming to solve the above problems existing in the prior art.

[0004] The present invention adopts the following technical solutions:

[0005] A method for generating a PSD file without relying on PS software, including the following steps:

[0006] (1) Represent the content to be written into the PSD file in the form of data;

[0007] (2) According to the PSD file format specification, convert the data in step (1) into the layer data corresponding to the PSD file;

[0008] (3) According to the data in step (1), set the file header data and color mode data according to the PSD file format specification;

[0009] (4) Write the file header data, color mode data, and layer data into a file in sequence in binary format to obtain a PSD file.

[0010] Further, if the content to be written into the PSD file in step (1) is text, then in step (2), directly map the data into layer data to form at least one text layer corresponding to the PSD file.

[0011] If the content to be written into the PSD file in step (1) is a picture, then in step (2), the data other than the pixel data is mapped into layer data to form at least one picture layer corresponding to the PSD file, and then the pixel data is stored in the pixel data mapping table, and the ID of the pixel data mapping table is associated with the layer data; in step (4), the file header data, color mode data, layer data, and pixel data mapping table are written into the file in sequence in binary format to obtain a PSD file.

[0012] If the content to be written into the PSD file in step (1) includes text and pictures, then in step (2),

[0013] For the text, the data of the text is directly mapped into layer data to form at least one text layer corresponding to the PSD file;

[0014] For the picture, the data other than the pixel data is mapped into layer data to form at least one picture layer corresponding to the PSD file, and then the pixel data is stored in the pixel data mapping table, and the ID of the pixel data mapping table is associated with the layer data;

[0015] In step (4), the file header data, color mode data, layer data, and pixel data mapping table are written into the file in sequence in binary format to obtain a PSD file.

[0016] Specifically, the data of the text includes font, font color, font size, text content, and distance from the canvas edge.

[0017] Specifically, the data of the picture includes the distance from the left side of the canvas, the distance from the top of the canvas, width, height, and pixel data.

[0018] A computer-readable storage medium stores computer-readable instructions, and when the computer-readable instructions are executed, any of the methods for generating a PSD file without relying on Adobe Photoshop software is implemented.

[0019] As can be seen from the above description of the structure of the present invention, the present invention has the following advantages:

[0020] The present invention represents the content to be written into the PSD file in the form of data, and then processes the data through file header data mapping, layer data mapping, pixel data mapping table, ID association, etc., and directly outputs a PSD file, which can generate a PSD file on electronic terminals such as computers, tablets, and mobile phones without installing Adobe Photoshop software, and can run on any operating system or platform (mobile phones, PCs, Pad browsers, etc. are all acceptable), and can better cross devices and platforms.

[0022] Figure 2 This is a schematic diagram of an embodiment of writing content in the present invention.

[0023] Figure 3 This is a simple schematic diagram of the PSD file format specification. Among them, File Header is the file header data, ColorMode Data is the color mode data, Image Resources is the content including additional information of the PSD file (this part is not the data that needs to be concerned in the present invention), Layer and Mask Information is the layer data, and Image Data is the pixel data mapping table. Specific Embodiments

[0024] The following describes the specific embodiments of the present invention with reference to the accompanying drawings.

[0025] Embodiment 1

[0026] As Figure 1 , Figure 2 and Figure 3 shown, a method for generating a PSD file without relying on PS software includes the following:

[0027] (1) Represent the content to be written into the PSD file in the form of data.

[0028] The above data includes canvas data, and the canvas data includes but is not limited to width, height, color mode, and background color.

[0029] The content to be written into the PSD file is mainly divided into two types: text and graphics. Among them, if the content to be written into the PSD file is text, the data that needs to be provided includes but is not limited to font, font color, font size, text content, and the distance from the canvas edge; if the content to be written into the PSD file is a picture, the data that needs to be provided includes but is not limited to the distance from the canvas edge, width, height, and pixel data, etc.

[0030] The ways to provide the above data include but are not limited to manual editing.

[0031] Taking Figure 2 shown as an example of the content to be written into the PSD file, the specific representation in the form of data is:

[0032] I. Canvas:

[0033] Width: 400px

[0034] Height: 400px

[0035] Color mode: RGB

[0036] Background color: Transparent

[0037] II. Content:

[0038] Layer 1:
