Bezier Envelope

This extension is similar to default Inkscape extension "Modify Path → Envelope" and is also similar to Another Perspective.

Note: this extension does not work for svg:circle which were converted to svg:path. Those will contain a or A commands in their path. We need to convert those to paths with c or C commands!

Draw the path you want to fit into the envelope

Draw your 4-sided envelope around

Please note!

• Paths with more than 4 sides will not correctly apply. Paths with less than 4 sides will fail. So just draw a square shape (angles don't have to be 90 degrees)
• Start in the upper left corner and draw clockwise. Otherwise your result may get twisted in an undesired way

Run the extension

First select the inner path. As second select the envelope. If you dismiss the order the extension will fail.
