GBMSIZE - Change the size of a bitmap
usage: gbmsize [-w w] [-h h] fn1.ext{,opt} [fn2.ext{,opt}]
flags: -w w new width of bitmap (default width of bitmap)
-h h new height of bitmap (default height of bitmap)
fn1.ext{,opt} input filename (with any format specific options)
fn2.ext{,opt} optional output filename (or will use fn1 if not present)
bitmap formats and options as before
If none of the -w or -h options are supplied, the defaults will be
the input image size. Hence this program will just read one file and
write the data as another. Great for format conversion.
