FilledPolygon with Image?

MrBodean

Is there a way to use the FilledPolygon routine to fill WITH another Image instead of a color?
I want to do Picture In Picture effects but that are not always rectangles, they might be at an angle, so I need to find a way to FILL a polygon array with another image.

I have tried passing another image in the function but does not seem to work.
imagefilledpolygon($image1, $values,8, $image2);

Can this be done? Is there another way to pull this off?

Thanks,
Jeff

Hi,

Mayke you can use this class, to create a mask of teh area to be included. Set the masked area to transparency, and merge the two images?

Masking the section is not the problem, I can do that. That again only lets you work with rectangles.

What I want it to fill and odd shaped polygon with an Image, so you could do things like perspective, put an image at a 3d angle so to speak. Not sure if it can even be done in php but checking 🙂

I haven't tried it (it's just an idea) but perhaps you could mask the to-be-cropped image with some other colour (allocate something like 100% magenta - "Magic Pink" - as an image colour), then mark it as transparent (with imagecolortransparent); finally imagecopymerge() it into wherever it's going. Be warned that any other pixels in the cropped image that are "Magic Pink" will also end up transparent.
