- Fix another regression caused by new feature to merge sibling groups (#260)
- Fix regression caused by new feature to merge sibling groups (#260)
- Fix issue with dropping xlink:href attribute when collapsing referenced gradients (#206)
- Fix issue with dropping ID while de-duplicating gradients (#207)
- Improve
--shorten-idsso it re-maps IDs that are already used in the document if they're shorter (#187) - Fix whitespace handling for SVG 1.2 flowed text (#235)
- Improvement: Merge sibling
<g>nodes with identical attributes (#208) - Improve performance of XML serialization (#247)
- Improve performance of gradient de-duplication (#248)
- Some general performance improvements (#249)
- Fix escaping of quotes in attribute values. (#152)
- A lot of performance improvements making processing significantly faster in many cases. (#167, #169, #171, #185)
- Fix exception when removing duplicated gradients while
--keep-unreferenced-defsis used (#173) - Remove some illegal optimizations of
m0 0sub-path commands (#178) - Fix and improve handling of boolean flags in elliptical arc path commands (#183)
- Fix exception when shorthand transform
scale(1)with single number is used (#191) - Fix exception when using two-number forms of the filter attributes
baseFrequency,order,radiusandstdDeviation(#192) - Improve whitespace handling in text nodes fixing an issue where scouring added spaces in error and reducing file size in many cases (#199)
- Drop official support for Python 3.3. (While it will probably continue to work for a while compatibility is not guaranteed anymore. If you continue to use Scour with Python 3.3 and should find/fix any compatibility issues pull requests are welcome, though.)
- Fix embedding of raster images which was broken in most cases and did not work at all in Python 3. (#120)
- Some minor fixes for statistics output.
- Greatly improve the algorithm to reduce numeric precision.
- Precision was not properly reduced for some numbers.
- Only use reduced precision if it results in a shorter string representation, otherwise preserve full precision in output (e.g. use "123" instead of "1e2" when precision is set to 1).
- Reduce precision of lengths in
viewBox(#127) - Add option
--set-c-precisionwhich allows to set a reduced numeric precision for control points.
Control points determine how a path is bent in between two nodes and are less sensitive to a reduced precision than the position coordinates of the nodes themselves. This option can be used to save a few additional bytes without affecting visual appearance negatively.
- Fix: Unnecessary whitespace was not stripped from elliptical paths. (#89)
- Improve and fix functionality to collapse straight paths segments. (#146)
- Collapse subpaths of moveto
mand linetolcommands if they have the same direction (before we only collapsed horizontal/verticalh/vlineto commands). - Attempt to collapse lineto
lcommands into a preceding movetomcommand (these are then called "implicit lineto commands") - Do not collapse straight path segments in paths that have intermediate markers. (#145)
- Preserve empty path segments if they have
stroke-linecapset toroundorsquare. They render no visible line but a tiny dot or square.
- Collapse subpaths of moveto
- Drop official support for Python 2.6. (While it will probably continue to work for a while compatibility is not guaranteed anymore. If you continue to use Scour with Python 2.6 and should find/fix any compatibility issues pull requests are welcome, though.)
- Fix: Unused IDs were not shortened when
--shorten-idswas used. (#19) - Fix: Most elements were still removed from
<defs>when--keep-unreferenced-defswas used. (#62) - Improve escaping of single/double quotes ('/") in attributes. (#64)
- Print usage information if no input file was specified (and no data is available from
stdin). (#65) - Redirect informational output to
stderrwhen SVG is output tostdout. (#67) - Allow elements to be found via
Document.getElementById()in the minidom document returned by scourXmlFile(). (#68) - Improve code to remove default attribute values and add a lot of new default values. (#70)
- Fix: Only attempt to group elements that the content model allows to be children of a
<g>when--create-groupsis specified. (#98) - Fix: Update list of SVG presentation attributes allowing more styles to be converted to attributes and remove two entries (
line-heightandvisibility) that were actually invalid. (#99) - Add three options that work analogous to
--remove-metadata(removes<metadata>elements) (#102)--remove-titles(removes<title>elements)--remove-descriptions(removes<desc>elements)--remove-descriptive-elements(removes all of the descriptive elements, i.e.<title>,<desc>and<metadata>)
- Fix removal rules for the
overflowattribute. (#104) - Improvement: Automatically order all attributes (#105), as well as
styledeclarations (#107) allowing for a constant output across multiple runs of Scour. Before order could change arbitrarily. - Improve path scouring. (#108)
Notably Scour performs all calculations with enhanced precision now, guaranteeing maximum accuracy when optimizing path data. Numerical precision is reduced as a last step of the optimization according to the--precisionoption. - Fix replacement of removed duplicate gradients if the
fill/strokeproperties contained a fallback. (#109) - Fix conversion of cubic Bézier "curveto" commands into "shorthand/smooth curveto" commands. (#110)
- Fix some issues due to removal of properties without considering inheritance rules. (#111)
- Add a function to sanitize an arbitrary Python object containing options for Scour as attributes (usage:
Scour.sanitizeOptions(options)).
This simplifies usage of the Scour module by other scripts while avoiding any compatibility issues that might arise when options are added/removed/renamed in Scour. (#44) - Input/output file can now be specified as positional arguments (e.g.
scour input.svg output.svg). (#46) - Improve
--helpoutput by intuitively arranging options in groups. (#46) - Add option
--error-on-flowtextto raise an exception whenever a non-standard<flowText>element is found (which is only supported in Inkscape). If this option is not specified a warning will be shown. (#53) - Automate tests with continuous integration via Travis. (#52)
- Add support for removal of editor data of Sketch. (#37)
- Add option
--verbose(or-v) to show detailed statistics after running Scour. By default only a single line containing the most important information is output now.
- Add functionality to remove unused XML namespace declarations from the
<svg>root element. (#14) - Restore unittests which were lost during move to GitHub. (#24)
- Fix a potential regex matching issue in
pointsattribute of<polygon>and<polyline>elements. (#24) - Fix a crash with
pointsattribute of<polygon>and<polyline>starting with a negative number. (#24) - Fix encoding issues when input file contained unicode characters. (#27)
- Fix encoding issues when using
stding/stdoutas input/output. (#27) - Fix removal of comments. If a node contained multiple comments usually not all of them were removed. (#28)
- Ensure Python 3 compatibility. (#8)
- Add option
--nindentto set the number of spaces/tabs used for indentation (defaults to 1). (#13) - Add option
--no-line-breaksto suppress output of line breaks and indentation altogether. (#13) - Add option
--strip-xml-spacewhich removes the specification ofxml:space="preserve"on the<svg>root element which would otherwise disallow Scour to make any whitespace changes in output. (#13)
- Fix ignoring of additional args when invoked from scons.
- Add option
--keep-unreferenced-defsto preserve elements in<defs>that are not referenced and would be removed otherwise. (#2) - Add option to ignore unknown cmd line opts.
- Add option
--shorten-ids-prefixwhich allows to add a custom prefix to all shortened IDs. (#1)
- Allow direct calling of the Scour module.
