Dear all,
I found this example in the garden.
\startMPclip{circleclip}
clip currentpicture to fullcircle shifted (.5,.5)
xscaled \width yscaled \height ;
\stopMPclip
\clip[nx=1,ny=1,mp=circleclip]{\externalfigure[hacker.png]}
Aside from the fact that I failed to understand the shifted argument by
playing around with values, I wonder if it is possible to use a SVG as
clip for an image.
The SVG is something like this:
<?xml version="1.0" encoding="UTF-8"?>
<!-- Created with Inkscape (http://www.inkscape.org/) -->
<svg width="20.887mm" height="17.613mm" version="1.1" viewBox="0 0
20.887 17.613" xmlns="http://www.w3.org/2000/svg";>
<g transform="translate(152.66 -101.94)">
<path d="m-150.94 114.93c-0.5424-1.3121-0.58209-2.9382 0.18256-5.2163
2.3566-7.0175 11.139-8.7098 15.878-3.0594 7.6978 8.7032-11.506
16.052-16.06 8.2756" fill="none" stroke="#dd4901" stroke-linecap="round"
stroke-width="2"/>
</g>
</svg>
I guess that there might be a way to translate this to Metafun or
Metapost, if I can't use SVG directly.
In my real life use case I want to have a bleeding image at the top or
the bottom of the page which can be clipped by the form while size and
position of the form relative to the image and relative to the page
shall be set by parameters either in \clip or in the definition of the
MPclip.
TIA
