Missing Font for Falsecolor

radiance-general

I tried to use the falsecolor program on an image and received an error:

nick@nick-desktop:~/scene1$ falsecolor -i scene1_bf.pic -p scene.pic -cl -s
12 -n 12 -l Lux > lux.pic
fatal - cannot find font file "helvet.fnt"

I'm missing Helvet[ica]? Seems like a weird error. Where do I get the font
file and in which file do I place it on my computer? (Ubuntu OS)

Thanks!

Hi Nick,

You need to make sure that helvet.fnt is in one of the directories in your $RAYPATH environment variable. This is explained (somewhat) in ray/README.

Best,
