Will TGA still be an editable camera RAW?+
Canon CRW needs camera- and file-aware development to produce a rendered TGA 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.
Will the background become transparent?+
The target can store an alpha channel, but converting an opaque image does not create transparent areas. Removing a background is a separate editing step.
Does lossless output mean an unchanged source?+
TGA can be uncompressed or losslessly RLE-compressed. Attribute bits and version-2 alpha semantics matter; the fourth byte must not automatically be treated as opacity. TGA 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.
Are bit depth and colour values guaranteed to match?+
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.
Will metadata and colour profiles be retained?+
Canon CRW: CIFF → TGA: Image ID, Extension area (v2). Which fields are copied, rewritten or omitted will depend on the future engine; retention is not implemented yet.
