Package: gimp-resynthesizer
Version: 0.16-1
Severity: important

About the bug:

The symptoms of the bug are that the plugin substitutes a texture that does NOT 
match the surroundings of the selection. 

The bug does not appear for every test case, but is repeatable for a given test 
case (except that resynthesizer uses a random seed and so the results are not al
ways identical.)  

The bug is more evident in black and white images, where there is less informati
on (only 8 bits instead of 24 color bits) for the plugin to find correct matches
.  The bug is more evident where the image contains much background "sky" and yo
u invoke the plugin on a selection in the foreground.

The essential part of the bug is in line 59 of the original, where a comment by 
the original author questions why the original code works and suggests alternati
ve code.  But the fix entails additional changes elsewhere.

lkk: these are my release notes for the patch (attached.)

A fix to the Gimp  Filter>Enhance>Smart remove selection... script.

Release notes:

IMPORTANT: Fixed a bug where strange texture (e.g. sky from the top of
the image) instead of surrounding texture was synthesized onto the
selection, as reported at the website http://registry.gimp.org/ for the
resynthesizer plug-in.

MINOR: Changed the menu item to "Filter>Enhance>Heal selection..." from
"Smart remove selection..." (Justification: New menu item name is
shorter and more descriptive.  It doesn't use the Heal tool, but the
effect is nearly the same.  Note the filename is the same, only the menu
item name is changed, and it still requires the separate resynthesizer
plug-in.)

Changed the pop-up help text. (Justification: more descriptive.)
