2013-08-04 16:20:21 -0600 | asked a question | [Android] add alpha channel to image Hi guys, So I am trying to remove a particular color from an image and then save the modified image as a png . Here's my code: The problem is that the image is always a black image .I thought it was a colorspace issue and I have tried many variations like Imgproc.COLORRGB2BGRA etc but that did not work either.Any ideas what could possibly be the problem ? Thanks! |
