    <p>I am trying to set a constant hue value for entire image with using ColorMatrix. My goal is to make entire image look with same color without loosing brightness of any area. I found a way to shift the hue values of an image by using ColorMatrix but i couldn't find any way to set same hue value for all pixels. I can do it with iterating every pixel of image but this approach is too slow. I am not sure if it is possible to do it with ColorMatrix and i am open to possible solutions other than ColorMatrix approach. </p> <p><a href="http://i.stack.imgur.com/36P7a.jpg">Input Image</a></p> <p><a href="http://i.stack.imgur.com/lvV7K.jpg">Hue shifting output Image*</a></p> <p><a href="http://i.stack.imgur.com/1LSYI.png">Desired output Image**</a></p> <p>*This can be done with color matrix</p> <p>** I can do this with iterating pixels but not with ColorMatrix</p> <p>PS: I am trying to do this on Android but i believe the question is not directly related to the android since ColorMatrix approach is common on other platforms like Flash, C# etc.</p>
