Hello,
You might try to use TVRead from David Fanning's website. It handles
all of the subtle issues regarding display depth, etc. I think he has
written in an additional bit of code for saving the image in different
formats. Liam Gumley has a similar program called SaveImage (you can
get it through David's annotate links page.)
Regards,
Ben

yes, thats how I was trying to write but its not working, even I work on
IDL 5.4, shall check it once more with your code and Reimar's
suggestion.

I feel this could be a problem with reading the display rather than some
problem with the code.

If this could be of any help this is the code I use
namejpg = 'sigmacoor.jpg'
jpg_pic=tvrd(0,0,xw_grids,yw_grids,true=3)
write_jpeg,namejpg,jpg_pic,true=3
It works fine for me with IDL 5.4 and win98.
Before using true=3 I had some problem with colours.
Ciao
Francesco
