Hello,
Could someone point me to an example of the best way to combine 2 images using color masking. I am using an ImageMorph with an image loaded and would like to overlay other images. I am thinking of trying BitBlt, but am wondering if there is an easier way.
Thanks.

1. get a "ScreeningMorph" from the alphabetical morph list (Alt-m) 2. drop in a source morph, for example, an image from a folder on your disk 3. drop in a screen morph, for example, an ellipse from the supplies flap

Nice one! Had not thought of using this to recolor sketches :)

Hi Derek,
The screening morph mentioned in previous posts is good.
Another interesting way do overlay images is to put them in as the graphic for a BitmapFill in a polygon. Then adjust the shape to show just the part you want.
For jigsaw pieces use a bunch of polygons. Line up polygons then giving each the same image for a fill and aligning the fill origin at the same point on the screen for each fill. Each polygon has its piece of the puzzle. Moving the polygons then moves the piece.
Yours in curiosity and service, --Jerome Peace.

Hi Jerome,
thanks for the tip. Here's one in return: to rotate and scale the polygon *and* it's bitmap fill embed the polygon in a holder, rotate/scale the holder then drag the polygon back out.
Regards,
Derek
