I need to write a program for managing my windows host, well actually, someone else’s windows laptop. I fired up TCL/TK and discovered that I haven’t copied my tcl/tk icon library from my home systems and I decided to improve my library, which is a big mistake.
I went looking on the ‘net and found the lovely Boomy icons. Annoyingly the transparency representation doesn’t work on my platform and the lovely transparency on the GIFs comes out a delightful shade of pink. There is no .bmp set; the .png set work and look fine. GIMP allegedly supports batch operations, as does Imagemagik. I have been impressed with Jonathan Soma’s trip map http://www.triptropnyc.com/ site about the New York transport system, which uses Imagemagik ever since I saw it, so an excuse to play with it would be good.
The alternative might be to find and install the TCL/TK IMG package which seems to be at SourceForge, http://sourceforge.net/projects/tkimg/.
I have opened a wiki page here, to record my notes, successes and failures, which now includes how to use ImageMagick to perform a simple format conversion.
