Save yourself some time. Don't make the mistake I made. Before you make an icon, see if it's already on the laptop!

===The Script===
===The Script===


In order to streamline the process of creating sugar compatible icons, we provide the [[olpc:media: sugar-iconify.py | sugar-iconify]] script.  This script takes an SVG file as input and outputs a new SVG (or SVGs) containing the proper entity definitions.  It offers a number of command-line flags for performing variations on this process to fit smoothly into your workflow.  You can view all of the available options by running <tt>sugar-iconify -h</tt> from the command line, or by viewing the dedicated [[olpc:Sugar-iconify | usage page]].  Some specific examples and use cases are illustrated below in more detail.

''Is there a way to render gradients using the fill color?  For example, if the child's XO fill color is red, I would like to render an activity icon using a red gradient.''


Here is an example of one way to do this by overlaying a gradient over the data-driven XO stroke and fill colors:

The "stop-color" properties of an SVG gradient will also accept the &stroke_color; and &fill_color; entities, if you want a gradient in the user's colors.  For example, this shows two gradients between transparent and opaque versions of the child's stroke and fill colors:
