I have a TGA 112 * 112 image, i want to add a 8*8 border to make a 128*128 OGLPVRTC4 image without any resize.
It works very well with the GUI version but i dont know what the command line version does.
If i dont put the -x and -y parameters it says "Power of two dimensions are required when TWIDDLE is enabled.".
if i use -x128 and -y128, it works but i think the image is resized in 128*128 and resized again to add the borders.
The API and the doc of the command line version is unclear about what it does.
