Core image // layer origin

Posted by Paul T on Oct 15, 2007

Hi i've been try to use the kaleidoscope effect in core image.

##
for i in range(5):
   
    l = canvas.layer("BMW_t.tif")
    l.origin_center()
    l.filter_kaleidoscope(count=1)
    l.blend(i*50)
    l.rotate(90)
##
At the moments it uses the centre of the image as the origin. I tried altering the origin of the layer but this just moves the layer to another area on the canvas.

I suppose what I really mean is that I would like to change the origin of the kaleidoscope, not the layer.

You can use the dx and dy parameters, which defines the origin of the kaleidoscope from the image's center:

l.filter_kaleidoscope(count=1, dx=50, dy=50)
