PdfDctCmykSamples class final

Four-channel JPEG samples in PDF CMYK polarity (0 = no ink, 255 = full ink), before the image XObject's colour space and /Decode are applied.

An embedding renderer may install pdfDctCmykDecoder to replace the portable package:image entropy/IDCT stage with an accelerated codec. The colour-management, masking, downsampling, and premultiplication pipeline remains here, so accelerated and fallback decoders share PDF semantics.
