PDL::Graphics::IIS Description

PDL::Graphics::IIS Perl module can display PDL images on IIS devices (saoimage/ximtool). PDL::Graphics::IIS Perl module can display PDL images on IIS devices (saoimage/ximtool).SYNOPSIS use PDL::Graphics::IIS; saoimage ( -geometry => '800x800' ); iis rvals(100,100);This module provides an interface to any image display 'device' which support the 'IIS protocol' - viz the SAOimage and Ximtool X-windows programs, the old SunView imtool program and presumably even the original IIS CRT itself if they aren't all in museums!These programs should be familiar to astronomer's - they are used by the common IRAF system. The programs and their HTML documentation can be obtained from the following URLs: SAOimage: http://tdc-www.harvard.edu/software/saoimage.html Ximtool: http://iraf.noao.edu/iraf/web/projects/x11iraf/x11iraf.htmlNon-astronomer's may find they quite nifty for displaying 2D data.The Perl variable $stdimage is exported from the module and controls the frame buffer configuration currently in use. The default value is imt1024 which specifies a 1024x1024 frame buffer. Other values supported by the module are: imt512, imt800, imt1024, imt1600, imt2048, and imt4096.If you have a $HOME/.imtoolrc you can use it to specify other frame buffer names and configurations in exactly the same way you can in IRAF. Here is a sample file: -------------------snip------------------------- # Format: configno nframes width height 1 2 512 512 # imt1|imt512 2 2 800 800 # imt2|imt800 3 2 1024 1024 # imt3|imt1024 4 1 1600 1600 # imt4|imt1600 5 1 2048 2048 # imt5|imt2048 6 1 4096 4096 # imt6|imt4096 7 1 8192 8192 # imt7|imt8192 8 1 1024 4096 # imt8|imt1x4 9 2 1144 880 # imt9|imtfs full screen (1152x900 minus frame) 10 2 1144 764 # imt10|imtfs35 full screen at 35mm film aspect ratio -------------------snip-------------------------(Note: some versions of SAOimage may not even work if this file is not present. If you get funny error messages about 'imtoolrc' try copying the above to $HOME/.imtoolrc or /usr/local/lib/imtoolrc)The Perl variable $iisframe is also exported from the module and controls which display frame number to use in programs such as Ximtool which supports multiple frames. This allows you to do useful things such as blink between images.The module communicates with the IIS device down FIFO pipes (special UNIX files) - unlike IRAF this module does a pretty decent job of intelligently guessing which file names to use for the pipes and will prompt for their creating if absent. Also if SAOimage or Ximtool are started from within Perl using the module this will guarantee correct file names! Requirements: · Perl
