Inkscape slicer

Download Inkscape slice effect a.k.a. 'slicer' 0.1.1 (bugfix)

Usage:

Create layer e.g. named 'slices'.
Create rectangles as your slices, set their Label* (select rect and Object -> Object properties) as the output filename (without extension).
Run Effects -> Export -> Slicer, specify directory where you want your slices to be saved and Apply.

What program does:

It takes all rectangles you give, puts opacity 0, stroke to none.
And tries to save contents inside rectangles to new files.
Returns the style to original value.

Installation:

Copy these two files (slicer.py, slicer.inx) to share/extensions directory inside inkscape, do not create directory for these files.

Extensions dir in common platforms:
Ubuntu 8.10 user scope: ~/.inkscape/extensions/
Ubuntu 8.10 global scope: /usr/share/inkscape/extensions/
Windows: c:\Program Files\Inkscape\share\extensions\

Thanks

Original idea from Matt Harrison:
WARNING, Matt's version didn't work with latest Ubuntu (8.10) and Inkscape 0.46, major API differences, that was the reason I rewrote whole script with features I needed. I have no intention to ripoff Matt's effort, so I fully thank Matt for his work, and if you somehow feel that I have broken the license in Matt's file you can contact me through comments in this blog.

Label allows all characters, where as ID allows only few. I need ability to use spaces in filenames so ID is no go. One can switch it to back to ID by changing line in slicer.py:
basename = rect_label.lstrip("#")
to
basename = rect_id
