    Description

      In attempting to convert a PDF which makes use of CMYK colours as well as colour transparencies, but the output I'm seeing doesn't match the input.

      I'm using the command line PDFToImage and have output in a lossless format and attempted to use all potential color depths to see if I can find a workable option.
