Uploading Images

Here are a couple of general rules for contributing to Privacy Guides:

Images

• We prefer SVG images, but if those do not exist we can use PNG images

Company logos have canvas size of:

• 128x128px
• 384x128px

Optimization

PNG

Use the OptiPNG to optimize the PNG image:

optipng -o7 file.png

SVG

Inkscape

Scour all SVG images.

In Inkscape:

1. File Save As..
2. Set type to Optimized SVG (*.svg)

In the Options tab:

• Number of significant digits for coordinates > 5
• Turn on Shorten color values
• Turn on Convert CSS attributes to XML attributes
• Turn on Collapse groups
• Turn on Create groups for similar attributes
• Turn off Keep editor data
• Turn off Keep unreferenced definitions
• Turn on Work around renderer bugs

In the SVG Output tab under Document options:

• Turn off Remove the XML declaration
• Turn on Remove metadata
• Turn on Remove comments
• Turn on Embeded raster images
• Turn on Enable viewboxing

In the SVG Output under Pretty-printing:

• Turn off Format output with line-breaks and indentation
• Indentation characters > Select Space
• Depth of indentation > 1
• Turn off Strip the "xml:space" attribute from the root SVG element

In the IDs tab:

• Turn on Remove unused IDs
• Turn off Shorten IDs
• Prefix shortened IDs with > leave blank
• Turn on Preserve manually created IDs not ending with digits
• Preserve the following IDs > leave blank
• Preserve IDs starting with > leave blank

CLI

The same can be achieved with the Scour command:

scour --set-precision=5 \
      --create-groups \
      --renderer-workaround \
      --remove-descriptive-elements \
      --enable-comment-stripping \
      --enable-viewboxing \
      --indent=space \
      --nindent=1 \
      --no-line-breaks \
      --enable-id-stripping \
      --protect-ids-noninkscape \
      input.svg output.svg
