To draw a bitmap more transparent then normal, I do the following : Paint paint = new Paint(Paint.FILTER_BITMAP_FLAG); paint.setAlpha(0x7F); canvas.drawBitmap(bitmap, matrix, paint);
This works great. The bitmap is half opaque... However, I also want to draw a bitmap with a red tint. One would think : Paint paint = new Paint(Paint.FILTER_BITMAP_FLAG); paint.setColor(0xFFFF0000); canvas.drawBitmap(bitmap, matrix, paint); would achieve that. But no. The bitmap is rendered normally. However, if I change it to : Paint paint = new Paint(Paint.FILTER_BITMAP_FLAG); paint.setColor(0x7FFF0000); canvas.drawBitmap(bitmap, matrix, paint); The alpha component of the color is indeed taken into account, but not the color channels. The bitmap shows up as half-opaque, but not red. In fact, I tried a number of colors, and the alpha is the only thing taken into account no matter what I pass in. So how can I go about applying a color multiplier to a bitmap when I draw it ? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
