Basic conversion

[Jocke]

Im doing a little project here!
And i need to have 64K TGA files

Been searching and looking on google and imagemagick seems to be the only serius alternative.

But i just dont seem to get my head around it,

Here is what i want my TGA file to be in the end (this is an exampel)

Trying a basic convert from a 64K bmp gives me a huge and unuseble TGA file..

Anyway, this is not my area of expertice, but im hoping to learn something =)

I have never tried this:

Code: Select all

convert input.bmp -resize 64000@ ouput.tga
