Emiliano almost has the complete answer: Frame buffers are configured by editing [b:cdadce1a83]both[/b:cdadce1a83] the imtoolrc file and the dev$graphcap file. From the FAQ:[quote:cdadce1a83]
What do I change to add a custom frame buffer size? There are two files that need to be modified to create your own frame
buffer size, imtoolrc and graphcap. You will need to restart the display
window to activate these changes. o First you need to copy over the system imtoolrc file into your home
directory, and then modify the file so it reflects your new frame
buffer size. Note the name change during the copy. % cd
% cp /iraf_path/dev/imtoolrc .imtoolrc
% vi .imtoolrc Go to the end of the file and add an entry for your particular frame
buffer following the examples in the file (contrary to what is in the
file, keep you frame numbers less than 64). o Next, copy over the system graphcap file and edit it in a similar fashion
following the examples under the "STDIMAGES devices" section. Now when
you log into IRAF point to this new graphcap file, and then reset the
value for stdimage. % cp /iraf_path/dev/graphcap mygraphcap
% vi mygraphcap
[restart the display window and log into the CL]
cl> reset graphcap = /home_path/mygraphcap
cl> gflush
cl> reset stdimage = my_new_frame_buffer When editing the graphcap entry be sure to modify the ":cn" (configuration
number) field as well as the buffer sizes (the
r and :yr fields as well
as the DD string). After resetting the graphcap environment variable be
sure to type a 'gflush' to reinitialize the graphics system.
