What happens when you convert Canon CR2 to TGA?

RAW development

Canon CR2 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.

Transparency

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.

Lossless sample storage

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.

Is Canon CR2 → TGA right for you?

Good choice when

  • TGA fits your delivery use: Textures & graphics assets.
  • You need a developed image for a non-RAW application.
  • You need lossless storage of the rendered samples supported by TGA.
  • You can validate the destination’s sample precision and colour interpretation.
  • You need a TGA-compatible workflow that can hold transparency added in a separate edit.

Probably not when

  • You need the original sensor data and freedom to redevelop it.
  • You expect lossless encoding to restore lost details or editing structure.
  • You require identical samples without a defined colour and precision policy.
  • You expect automatic background removal or transparency.

Canon CR2 to TGA conversion details

RAW development
Canon CR2 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.
Transparency
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.
Lossless sample storage
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.
Sample precision & colour
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.
Metadata & colour
Format support does not guarantee that an export preserves metadata or colour profiles. Retention and colour handling depend on the future converter; its engine is not implemented yet.
Compression
Canon CR2: Depends on variant → TGA: Lossless Canon CR2: Raw precision and reduced-size recording modes depend on the camera. A lossless compression stage does not imply that a reduced-size raw has identical data to a full-resolution capture. Use the camera documentation and a decoder that supports that exact model and mode. TGA: 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.
Transparency
Canon CR2: No → TGA: Yes
Colour depth
Canon CR2: Camera and recording mode → TGA: Indexed / gray / RGB / RGBA
Sensor data
Canon CR2: Raw development required
Dimensions
Pixel dimensions, page geometry, rendering resolution, resizing and orientation need explicit converter policies. The future engine has not defined them yet.
Metadata
Canon CR2: Capture metadata → TGA: Image ID, Extension area (v2). Which fields are copied, rewritten or omitted will depend on the future engine; retention is not implemented yet.

Common questions

Will TGA still be an editable camera RAW?

Canon CR2 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 CR2: Capture metadata → TGA: Image ID, Extension area (v2). Which fields are copied, rewritten or omitted will depend on the future engine; retention is not implemented yet.
