In all LEADTOOLS versions, the image is converted to RGB
automatically when it is loaded into memory. If you save it back to a CMYK format, it is converted back from RGB to CMYK.

 However, in version 14.5 you can load 4 different CMYK
planes into an array of 4 images using the function
"L_LoadFileCMYKArray()" and then Paint into the screen using the
function "L_PaintDCCMYKArray()"and save them using the "L_SaveFileCMYKArray()" function.

You can perform certain types of image processing on the 4
planes, such as rotation. If you don't have LEADTOOLS 14.5, you can download a free evaluation edition from our site.
