Camera RAW requires full image development. This browser engine does not implement it yet.
Canon CRW needs camera- and file-aware development to produce a rendered PCX image. White balance, exposure, camera colour interpretation and, where applicable, demosaicing determine that rendering. The destination does not retain the original RAW development latitude. No development settings or camera support are implemented yet.
PCX RLE is lossless for stored samples. Palette reduction is a separate potentially lossy step; colour planes are channels, not editable composition layers. PCX can store its supported image samples without lossy compression. This applies after rendering and sample conversion: it does not guarantee preservation of source precision, colour space or document structure, and cannot undo earlier losses.
The reviewed PCX representation uses 8-bit colour samples. If the source contains higher-precision samples, they must be reduced before encoding, even in a lossless output mode. Rounding, dithering and colour conversion are future engine decisions; lost precision cannot be recovered from this output.

Source and target sample models can differ in precision, channel layout, colour space and transfer function. Lossless compression only preserves the samples actually encoded; a precision reduction or colour conversion can already change them. The future engine defines numeric mapping, orientation and colour conversion; canonical depth facts are listed below where available.
Canon CRW: CIFF → PCX: Resolution, Palette information. Which fields are copied, rewritten or omitted will depend on the future engine; retention is not implemented yet.
