svg_alpha_fix

Fixes svg images that don't render properly in inkscape, extracts alpha from color and puts it in opacity attribute.

Example:

fill="rgba(1,2,3,50%)"

Becomes:

fill="rgb(1,2,3)"
fill-opacity="50%"

Example2:

fill="#00ff0080"

Becomes:

fill="#00ff00"
fill-opacity="0.502"

The following attributes will be parsed:

• fill (will create fill-opacity)
• stroke (will create stroke-opacity)
• flood-color (will create flood-opacity)

fix SVG file alpha property

Use either svg_convert_regex.py or svg_convert_xml.py (requires lxml python module). By default they don't prettify, but they do remove leading and trialing whitespace.

How to use it:

• pass paths of files to the scripts e.g. svg_convert_regex.py file.svg or drag them onto the script if dragging onto python files is enabled on your system
• or drag onto svg_convert.cmd to use svg_convert_regex.py
• or call svg_alpha_fix()*

*note that svg_convert_xml.py only accepts filenames and svg_convert_regex.py only accepts strings. svg_convert_xml.py's svg_alpha_fix() removes xml declaration and needs to be added back manually if needed.

Prettify

xml_prettify.py has a prettify function that respects xml:space="preserve" and preserves significant whitespace if needed. It preserves the xml declaration. It also keeps comments and CDATA. It doesn't preserve or process DTD.

• prettify_string() accepts XML string and returns prettified XML string
• prettify_file() accepts XML filename and returns prettified XML string
• process_xml_declaration() accepts XML string and returns the XML declaration (used internally to preserve XML declaration)

How to use it:

• pass paths of xml files to the script e.g. xml_prettify.py file.svg or drag them onto the script if dragging onto python files is enabled on your system
• or drag onto xml_prettify.cmd to use xml_prettify.py
• or call prettify_string() or prettify_file()
