text to image

[Viktoras Didziulis]

 Hi,
 
I have a text file which stores space (or tab) delimited rgb values. Height
and width is defined as Y and X. Is there any straight-forward way to
convert it to image in Transcript?
 
Or yet more complex problem - given an text file of (tab delimited) values
(e.g. elevation raster), is there any shortcut "ale Transcript" to convert
it to image within specified color range (min rgb - max rgb) of pixels?
 
Many thanks in advance!
Best regards
Viktoras
