Revision history for Perl extension Image::DS9.

0.182 Wed Dec 16 20:24:39 EST 2009

• updated grammar to match DS9 5.7 for commands cd, frame, height, width, view, frame
• fixed broken wcs append & replace
• added pan query for just physical & image

0.181 Mon Jun 1 11:34:42 EDT 2009

• tests now pass against ds9 5.6.3. They have not been extended to match all of the new functionality, but at least they pass.

0.18 Mon Sep 30 20:37:37 EDT 2002

• added ResErrXXX options
• fixed contour save/load grammar
• bin cols could return 3 values; kludge that in
• sometimes? when DESTROY'ing object would have undefined xpa object. why?? now checks for that.
• error message clean up in Parser
• now accepts colormap as an alias for cmap.

0.17 Wed Sep 25 17:00:03 EDT 2002

• added Image::DS9::Constants
• revamped test suite

0.16 Mon Sep 23 18:34:45 EDT 2002

• most of DS9's access points are now supported.
• now uses a table driven parser to generate the methods and data conversion between Perl and DS9.
• realized the futility of keeping the docs up-to-date in parallel with DS9. Now just list the options supported, rather than duplicate the DS9 docs.
• the display() and tile_mode() methods are no longer supported. display() was an attempt to unify tile, blink, and single in a clean way. I've decided to just track the actual XPA access methods rather than foist my view of how things should tie together. So, display() should be replaced with the appropriate calls to tile(), blink(), or single(). tile_mode() was really tile() all along...
• earlier versions of this package had a gadzillion constants for all of the commands and subcommands and enumerated values. this was a real mess. the constants are now in their own package (Image::DS9::OldConstants), and are deprecated.

0.15 Tue Jan 29 12:27:06 EST 2002

• added dss()

0.14 Mon Jan 28 15:12:24 EST 2002

• updated nservers() to track new IPC::XPA::Access API.

0.13 Tue Oct 30 00:24:14 EST 2001

• results buffer splitting didn't ignore leading white space, leading to extra leading elements in the returned array.
• added pan function
• added regions load and save options
• scale(S_limits) wasn't calling Get properly to return the limits.
• wcs query had wrong value of reswanthash in _Get call
• DS9 v2.1 uses 'cmap' instead of 'colormap'. I've switched over to 'cmap' since everyone should upgrade to DS9 v2.1.

0.12 Mon Oct 22 10:18:27 EDT 2001

• removed definitions of TRUE and FALSE; was causing Export problems.

0.11 Fri Oct 12 13:22:02 EDT 2001

• implemented scale datasec

0.11 Thu Oct 11 17:35:35 EDT 2001

• frame hide now takes an argument (so can do hide all)
• frame all implemented so can get list of all frames
• updated tile_mode so that one can set/get the grid mode attributes.

0.106

• more aggressive cleaning of WCS keywords

0.105

• colormap was incorrectly looking at $state instead of $colormap when looking for the inversion tag

0.104 Mon Aug 13 14:17:46 EDT 2001

• ensured that the CTYPE? WCS keywords are surrounded by apostrophes

0.103

• didn't create the wcs export tag

0.102

• Forget Rg_file in export list 0.101
• array() may now take a one-dimensional piddle
• cleaned up detection of piddles

0.10

Externals

• added invert option to colormap()
• added save option to file()
• added bin()
• added crosshair()
• added cursor()
• added lower()
• added raise()
• added regions()
• added wcs()
• added view()
• renamed T_Grid, T_Column, and T_Row to T_grid, T_column, T_row
• iconify() didn't return a true/false value (it directly returned what DS9 sent it).
• bugs fixed in display() code for queries which had errors
• fixed up return for scale(S_limits) to be more consistent
• Set() and Get() (low level access to XPA channel) are now documented

Internals

• cleaned up module setup code and creation of export tags
• lots more error checking of arguments. this may make following updates to DS9 a little more work, but makes it easier for users of this module
• improvements to documentation

0.09 Fri Sep 8 23:31:03 EDT 2000

• confused max index with number of elements in check for correct number of arguments for scale( 'limits' )

0.08 Wed Aug 2 12:15:40 EDT 2000

• made compatible with API change in IPC::XPA v0.04.
• Get() now more flexible about chomping buf and messages;
• implemented reswanthash attribute
• implemented verbose attribute
• most ops arrays available as useful ones as @xxx_ops_dbg
• cleaned up ops stuff a bit to make less problematic to add stuff
• queries now take into account whether in list or scalar mode and return either the hash or the value of {buf}, respectively
• added iconify(), mode(), orient(), rotate().
• made scale(), zoom(), and display() queryable

0.07 Thu May 11 13:48:37 EDT 2000

• max_servers could default to zero if no servers were running; this would cause problems later if one was started up. it now defaults to at least one.
• $self->{res} is always updated after Set.
• the frame show command was incorrectly implemented.

0.06 Wed May 10 13:24:39 EDT 2000

• renamed frame ops once more
• renamed file ops to filetype
• removed tile() and blink()
• move _Set() and _Get to Set() and Get(); no docs yet
