Gradually change colour of a bitmap?
<p>I've got several bitmaps on the screen that gradually need to change colours depending on values they are set. I've looked into LightingColorFilter, PorterDuffColorFilter and ColorMatrix but the problem is the colours change constantly (tens of times a second and many objects). The problem with the 2 above is they create memory leaks and performance problems.</p>

<p>Can anyone suggest a way of gradually changing the colour of the bitmap (without creating a new bitmap or storing the canvas temporary? - also performance hinders). I've looked around and it doesn't seem possible without OpenGL (Something I have no clue about).</p>
