[daip] modifying aips

[Ibrahima Bah]

hi,
While using aips, i have failed in doing grey scale contour overlap on 
specific places of radio and IR images with the same galactic coordinates.  
However i have come to realize that aips do not offer this option with the 
kntr task.  Therefore i decided to modify this task so it that it can do 
grey-scale on selected parts of these images.  In other words to have the 
option of setting ttrc, tblc, tyinc and txinc of different images for 
grey-scaling.  However after seeing the coding for this task, i realize that 
this promises to be a really complex and hard job for that the coding is 
very long and my understanding of fortran is limited.  My questions are 1 is 
there a way other than the kntr task to do this with out having to cut-up 
peices from these images and creating knew ones? 2 if not how can i get 
assistances in modifying the kntr function?  Thank very much!
