Change a code execution results can be normal output BMP images, can perfect opening in the drawing, as shown in figure
But when the image is opened in PS will appear the following situation
And then I in drawing software will save as BMP images, PS can be perfectly open,
Using the binary editor to view the files and found two file in BMP file header is slightly different, but using code generation of the original documents must be no problem, so drawing software in the save as it will change the image, what is this principle, can use PS perfect open code generated source files,
