[pstricks] fill around image

[Olivier .]

Hi Henry,

I've already had this kind of issue. For a quite
simple image, if you vectorize it and with a soft like
Illustrator, you delete the contour, youll' then have
an image with no contour looking like a "transparent"
image. This is the only way I've found.

Another way is, for instance, to include your image
within a circle, an ellipse or a square and then the
image will fit inside the shape.

Hope this can help

Olivier
