hi,

newbie for Rmagick…

is there any methods to crop or clipp original image with 4 corners
coordinates (xi, yi) i=1…4. Have seen it is possible to use
ImageList::crop(x,y,heigth, wigth) to get a rectangle sub-image.

thanks in advances!

If you want something general, look at the methods define_clip_path
and clip_path of the class Draw. Take a special look to the example of
the clip_path method (just click on the image to see the code) in the
RMagick doc.

thanks in advances!

I hope it to help you.
