I don't know of an editor that will doing scaling operations (although
LDAO's Editor *should*). I can think of two solutions:
1. Keep your image.dat as a separate file. Whenever you need to use it,
reference it like a part-file. To scale, change the parameters on the
file-reference commandline:
1 16 0 0 0 0.5 0 0 0 0.5 0 0 0 0.5 image.dat
Change the '0.5' values to whatever scale you want.
2. To make a new file, or to prepare code for inclusion in another file,
use a spreadsheet program. Open your image.dat in your favorite
spreadsheet. Multiply all the position/orientation parameters by whatever
scale you want. Save to newimage.dat.
