I have a pdf in which one particular image has a DeviceCMYK colorspace and DCTDecode filter. When i convert it to image it gets weird background color. i got warning "YCbCr JPEGs not implemented". so i implemented it and it renders right image after that.

i attached the pdf and patch. issue is on first page of pdf.
