Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

PDL::Graphics::IIS - Display PDL images on IIS devices (saoimage/ximtool)
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: Ximtool: Non-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 copy- ing 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!
iis Displays an image on a IIS device (e.g. SAOimage/Ximtool) iis $image, [ { MIN => $min, MAX => $max, TITLE => 'pretty picture', FRAME => 2 } ] iis $image, [$min,$max] (image(m,n),[\%options]) or (image(m,n),[min(),max()]) Displays image on a IIS device. If "min()" or "max()" are omitted they are autoscaled. A good demonstration of PDL threading can be had by giving "iis()" a data *cube* - "iis()" will be repeatedly called for each plane of the cube resulting in a poor man's movie! If supplied, "TITLE" is used to label the frame, if no title is supplied, either the "OBJECT" value stored in the image header or a default string is used (the title is restricted to a maximum length of 32 characters). To specify which frame to draw to, either use the package variable $iisframe, or the "FRAME" option. iiscur Return cursor position from an IIS device (e.g. SAOimage/Ximtool) ($x,$y) = iiscur($ch) This function puts up an interactive cursor on the IIS device and returns the "($x,$y)" position and the character typed ($ch) by the user. iiscirc Draws a circle on a IIS device (e.g. SAOimage/Ximtool) (x(),y(),radius(),colour()) iiscirc $x, $y, [$radius, $colour] Draws circles on the IIS device with specied points and colours. Because this module uses PDL::PP threading you can supply lists of points via 1D arrays, etc. An amusing PDL idiom is: perldl> iiscirc iiscur Note the colours are the same as IRAF, viz: 201 = cursor color (white) 202 = black 203 = white 204 = red 205 = green 206 = blue 207 = yellow 208 = cyan 209 = magenta 210 = coral 211 = maroon 212 = orange 213 = khaki 214 = orchid 215 = turquoise 216 = violet 217 = wheat saoimage Starts the SAOimage external program saoimage[(command line options)] Starts up the SAOimage external program. Default FIFO devices are chosen so as to be compatible with other IIS module functions. If no suitable FIFOs are found it will offer to create them. e.g.: perldl> saoimage perldl> saoimage( -geometry => '800x800' ) ximtool Starts the Ximtool external program ximtool[(command line options)] Starts up the Ximtool external program. Default FIFO devices are chosen so as to be compatible with other IIS module functions. If no suit- able FIFOs are found it will offer to create them. e.g. perldl> ximtool perldl> ximtool (-maxColors => 64)
