I put up a new BmpUtil on the cbloom.com/exe page .

FimUtil sizers are much better than the BmpUtil ones. TODO : any resizing except doubling/halving is not very good yet. FimUtil eq & eq2 provide a pretty generate equation parser, so you can do any kind of per-sample manipulation you want there. "bmputil copy" is how you change file formats. Normally you put the desired jpeg quality in the file name when you write jpegs, or you can use "bmputil jpeg" to specify it manually. Unless otherwise noted, fim pixels are in [0,1] and bmp pixels are in [0,255] (just to be confusing, many of the fimutil commands do a *1/255 for you so that you can pass [0,255] values on the cmd line); most fim ops do NOT enforce clamping automatically, so you may wish to use ClampUnit or ScaleBiasUnit. Yeah, I know imagemagick does lots of this shit but I can never figure out how to use their commands. All the source code for this is in cblib, so you can examine it, fix it, laugh at it, what have you.
