aricb A poster on comp.lang.tcl [L1 ] was looking for code to convert a rectangular set of floating point values into a color image, similarly to MATLAB's imagesc. I used to do some data visualization in a previous life, so I thought I'd bite. Critiques welcome.
The main command is valuesToImg; see comments just inside that proc for available options.
