This approach provides several advantages over previous methods. IRAF will ask DS9 for the current filename and use it for analysis. Then, from the cl prompt, invoke imexamine without a filename. Instead of loading the image from IRAF with the display task, load the image directly into DS9. Before using msczero, issue the following command in the cl: cl> set disable_wcs_maps=""ĭue to the unique relationship between DS9 and IRAF, if you use the imexamine task, you can take advantage of a special feature of DS9. However, there is one minor problem with the mscred task msczero. So this is why, the SCALE menu is disabled in DS9 when it receives a image from IRAF.ĭS9 now supports IRAF's new IIS image display protocol. What actually is sent from IRAF to DS9 is one byte per pixel, values 0-200, which already has applied both the upper and lower clipping bounds and the distribution. Here are the DISPLAY parameters in question: parameters to set the upper/lower bounds and distribution. In Display, use the ztrans and z1, z2 zscale parameter to auto determine z1,z2. When you display an image from IRAF into DS9, IRAF actually does the color scale distribution. For example, if the windows machine is named '', define IMTDEV to the follow value before entering IRAF. To direct image output from IRAF to DS9 running under windows, use the IMTDEV environment variable. imtoolrc might define old frame buffer configs which might confuse things, so if the system file exists check for a private copy screwing things up. Users can also just copy dev$imtoolrc to $HOME/.imtoolrc and restart the server to also workaround it. The fix is the create the dir and rerun the install script or else make the link by hand. This is created as a symlink to dev$imtoolrc by the iraf install script but only if the /usr/local/lib dir already exists on the machine. The messages means that there is no /usr/local/lib/imtoolrc file on the machine. If your system administrator has made changes to graphcap, they must also be implemented in imtoolrc. If on the other hand, IRAF assumes a different buffer size, the image will appear corrupted and DS9 may issue a number of error messages.Īnother problem is that this file must be in sync with dev$graphcap. If no configuration file is found, DS9 will assume the following default configuration: 1 2 512 512 # imt1|imt5880 # imt9|imtfs full screen (1152x900 minus frame)ġ0 2 1144 764 # imt10|imtfs35 full screen at 35mm film aspect ratioġ3 # imt13|imttall128 tall & narrow for spectro.ġ4 # imt14|imttall256 tall & wider for spectro.ġ5 2 1056 128 # imt15|imtwide128 wide & thin for spectro.ġ6 2 1056 256 # imt16|imtwide256 wide & fatter for spectro.ġ7 2 1008 648 # imt17|imtssy Solitaire fmt w/ imtool borde680 # imt18|imtssn Solitaire fmt w/out imtool border If not found, it will look for shell environment variables IMTOOLRC and imtoolrc, that contains the name of the configuration file. So when an image server starts (DS9), it will attempt to locate this file as $HOME/.imtoolrc and / usr/local/lib/imtoolrc. What actually passes from IRAF is not the buffer size, but an index number into this file. The default parameters are: fifo /dev/imt1Īn IRAF image server uses a configuration file to specify the number of available buffers and their sizes. ![]() ![]() Support full postscript printing of images loaded from IRAF is provided.Īs with ximtool, the follow command line arguments may be used to specify the communication parameters: fifo DS9 supports IRAF in all display visuals including Truecolor. Values displayed may the the true values, if a linear scale is specified with the display command. And DS9 now supports IRAF's new IIS image display protocol that supports up to 16 display frames.Īll native DS9 functions may be used with images load with IRAF display except for the Scale menu items. If you have one of the above currently working, DS9 works right out of the box. IRAF uses the IIS protocol to communicate with a valid image display server, such as DS9, ximtool, saoimage, and saotng. DS9 is a fully functional IRAF image display server.
