We have created a custom wrapper around various Aspose asemblies, including Aspose.Pdf. We have a customer who was unable to add a watermark to a PDF document using a CMYK-format JPEG. Older versions of Aspose.Pdf didn't seem to have a problem with this, and RGBA-format images still work fine, too.
From reading other posts, it looks like CMYK-format images are no longer (or were never) supported, or at least not fully/properly. Will this format be supported in the future?
I've attached the original PDF document used, the watermarked document, and the CMYK-format JPEG.
