I used photoshop, I don't know about any free phograms for editing .tga files but i hope that some egsist.

Also I find that is no visible loss of quality during converting to
.bmp format and back for recognition manual pages.

I used ACDsee(also comercial) build-in tool to format convet.

I think it will be easier to find in the net free .tga-to-somthing converting tools then free .tga edit program
