How to draw contours in color in 4 channel image?

asked 2019-10-30 12:12:29 -0500

The contours I am drawing to the 4 channel image come up as white instead of the colors I specified for the parameters. Is there something I am missing before drawing the contours?

I tested my function by converting my image from RGBA to RGB. I was able to get color contours on the RGB image. Is there any restrictions on color contours for RGBA? Could not find anything about that.
