Pixel decoding and image re-encoding: how TGA becomes BMP

Converter.now decodes Truevision TGA raster data supporting direct color, palettes, alpha, and optional run-length encoding into a working pixel canvas, then writes that canvas according to BMP's color and compression model. Dimensions may stay constant while encoding, metadata, and fine detail change. TGA decoding follows image type, origin, pixel depth, palette, run-length packets, alpha bits, and scan direction from its descriptor fields. BMP output writes a single flat pixel surface with an explicit row order and color depth, built for simple bitmap interchange rather than layers or multiple resolutions.

Decoded canvas - Truevision TGA raster data supporting direct color, palettes, alpha, and optional run-length encoding. Written image - A plainly structured bitmap with minimal compression that most software can read.

When to actually choose TGA to BMP

BMP wins this route whenever its specific mix of compatibility, alpha, animation, and file size fits the destination better than TGA does.

What changes between the TGA model and the BMP deliverable

The source stores Truevision TGA raster data supporting direct color, palettes, alpha, and optional run-length encoding; the destination stores a plainly structured bitmap with minimal compression that most software can read. Compare application metadata after that structural change.
TGA and BMP use different metadata conventions, so application-specific fields should be treated as optional until verified.

Reading TGA correctly and satisfying what BMP expects

TGA

What can fail when TGA raster image is interpreted

Image origin flags can flip the picture, and alpha may represent transparency or another channel in production assets.

BMP

What BMP raster image cannot safely promise

A BMP derivative is typically far larger than a web-oriented image, and row order or alpha handling can differ between the apps that read it.

ENGINE

How the BMP writer handles this route

The writer builds a plainly structured bitmap with minimal compression that most software can read and labels the result as image/bmp. The receiving application - Not the extension alone - Is the final compatibility test.

Acceptance evidence for the converted BMP

BEFORE

Record the TGA evidence before conversion

Verify orientation, channel order, alpha meaning, bit depth, palette, and dimensions in the destination renderer.

AFTER

Test the BMP file in its receiving workflow

Check the dimensions, color depth, and orientation, and confirm whether the app you're using actually reads BMP transparency.
