scour.py, scour.inkscape.py, scour.inx: * Add options --quiet, --enable-comment-stripping, --shorten-ids, --remove-metadata, --renderer-workaround. scour.py: * Optimisations in time (so Scour runs faster) and space (so Scour allocates less memory, less often). * Change #E+# to #e#, #E-# to #e-#, 0.# to .# and -0.# into -.# in path/polygon/polyline data + lengths, if renderer workarounds are disabled. Use spaces instead of commas in path/polygon/polyline data. Use lower-case #rrggbb and #rgb instead of upper-case. All of this makes gzip work better, since the rest of SVG documents mostly has lower-case letters in tag names and spaces to separate XML attributes etc. * Fix a bug whereby an SVG document would become filled with black if all elements had the same fill color. * Fix a bug whereby a path's second command would not start at the right coordinates if the first command was a relative moveto 'm' with at least 1 implied lineto. * Fix a bug whereby a path's absolute lineto 'L' commands would not become the right relative lineto 'l' commands. * Allow the implicit linetos after a path's moveto 'M'/'m' to be converted into relative horizontal linetos 'h' and vertical 'v' too. scour.inx: * Fix help typos. Make options more descriptive in the plugin option window. Add something about enable-group-collapsing requiring enable-id-stripping. testscour.py: * Rework tests that relied on #E+#, #E-#, 0.# and -0.# so that they accept the changes to scour.py. Add unit tests for strip-xml-prolog, enable-comment-stripping and remove-metadata.

<_param name="instructions" type="description" xml:space="preserve">This extension optimizes the SVG file according to the following options:
|
|
* Shorten color names: convert all colors to #RRGGBB or #RGB format.
|
|
* Convert CSS attributes to XML attributes: convert styles from <style> tags and inline style="" declarations into XML attributes.
|
|
* Group collapsing: removes useless <g> elements, promoting their contents up one level. Requires "Remove unused ID names for elements" to be set.
|
|
* Remove unused ID names for elements: remove all unreferenced ID attributes.
|
|
* Shorten IDs: reduce the length of all ID attributes, assigning the shortest to the most-referenced elements. For instance, #linearGradient5621, referenced 100 times, can become #a.
|
|
* Embed rasters: embed raster images as base64-encoded data URLs.
|
|
* Keep editor data: don't remove Inkscape, Sodipodi or Adobe Illustrator elements and attributes.
|
|
* Remove metadata: remove <metadata> tags along with all the information in them, which may include license metadata, alternate versions for non-SVG-enabled browsers, etc.
|
|
* Remove comments: remove <!-- --> tags.
|
|
* Work around renderer bugs: emits slightly larger SVG data, but works around a bug in librsvg's renderer, which is used in Eye of GNOME and other various applications.
|
|
* Enable viewboxing: size image to 100%/100% and introduce a viewBox.
|
|
* Number of significant digits for coords: all coordinates are output with that number of significant digits. For example, if 3 is specified, the coordinate 3.5153 is output as 3.51 and the coordinate 471.55 is output as 472.
|
|
* XML indentation (pretty-printing): either None for no indentation, Space to use one space per nesting level, or Tab to use one tab per nesting level.</_param>
