Explanation

The IKPngFileSaveMem function saves raster image data in PNG format as raw image data. Supports 1, 4, 8 and 24 bit color.

If the user function is set or if the Caption, Message, and Button parameters are blank then the Progress dialog box is not displayed. If the Progress dialog box is displayed, it indicates the percentage of the current process completed. For more information about the user function please refer to the Definition of User Function in the Ik9File.dll, Ik9FileA.dll, Ik9File64.dll, Ik9File64A.dll section.

Except for the fact that the raster image is saved as raw image data, this function operates in the same way as the IKPngFileSave function.
