Technical note

TGA to CAL: what carries over and what does not

TGA can carry an alpha channel and CAL cannot. Transparent areas are composited onto a solid background during conversion, so pick that background colour deliberately: white is the default, and it is rarely the right choice for a logo that will sit on a dark page. TGA carries 8 bits per channel and CAL carries 1, so tonal steps get coarser during conversion. It shows up first in smooth gradients such as skies. If the result will be edited further, move to a 1-bit format only at the very end.

FAQ

TGA to CAL Conversion

What are TGA files?

The TGA (Truevision Graphics Adapter) format, also known as Truevision TGA or TARGA, is a bitmap file containing raster graphics and was initially associated with TARGA and VISTA boards. TGA files can be used on DOS, Windows and Mac OS X platforms for storing and transferring deep-pixel images. They support a color range of up to 24 bits and an 8-bit alpha channel. TGA files are associated with graphic adapters that can capture NTSC and/or PAL video images signals, and they are particularly popular in the domain of still-video editing.

What are CAL files?
