[Radiance-general] Re: falsecolor and textlabels question

[Greg Ward]

Hi Pierre-Felix,

On X11 displays that support 8-bit color lookup mode, you can use the 
-b option of ximage and the 'i' command to create contours, labelling 
them manually with the 'l' command.  This doesn't work on a lot of 
modern graphics cards, unfortunately.  The -cl option of falsecolor is 
your next best option.  Or, if you don't like that one, try -cb.

One of my favorites is to generate both an illuminance image and a 
regular image, then combine them with falsecolor:

% rpict [options] octree > regular.pic
% rpict [same options] -i+ octree > illum.pic
% falsecolor -cl -i illum.pic -l Lux -p regular.pic > isolux.pic

Hi!
 
I am successfully generating falsecolor images and found the labels 
that find the lowest and hightest values quite useful.  Do you know a 
way to add more labels in the image for intermediate values?
 
Thanks in advance,
