> 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.
