(1) the content to be written to the PSD file is represented in the form of data.
The data includes canvas data including, but not limited to, width, height, color pattern, and background color.
The contents to be written into the PSD file are mainly divided into two types, text and graphics. If the content to be written into the PSD file is a text, the data to be provided includes, but is not limited to, a font color, a font size, a text content, and a distance from an edge of the canvas; if the content to be written to the PSD file is a picture, the data to be provided includes, but is not limited to, the distance from the edge of the canvas, the width, the height, and the pixel data.
The manner of providing the above data includes, but is not limited to, employing manual editing.
Taking the content to be written into the PSD file as an example shown in fig. 2, the data format specifically indicates that:
firstly, canvas:
width of 400px
Height of 400px
Color pattern RGB
Background color transparent
Secondly, content:
layer 1:
type of character layer
Font, Alibap Heavy
Font color red
Font size 40px
Text content i am a cat
Distance from left side of canvas 40px
Distance from canvas top 40px
And (3) layer 2:
type picture layer
Distance to left of canvas 100px
Distance from canvas top 100px
Width of 200px
Height of 200px
Pixel data [ binary image data ].
Since it is prior art to generate a pixel picture from binary image data, the detailed binary image data corresponding to the picture shown in fig. 2 is omitted here.
(2) And (3) converting the data in the step (1) into layer data corresponding to the PSD file according to a PSD file format specification.
Specifically, for data of a text part, the data of the text is directly mapped into a map layer data to form a text map layer corresponding to the PSD file.
And for data of the picture part, mapping data except the pixel data into picture layer data to form a picture layer corresponding to the PSD file, then storing the pixel data into a pixel data mapping table, and associating the ID of the pixel data mapping table with the layer data.
