How to change colormatrix x,y coordinate of image?

Question

I am developing an app which allows users to color the images. I have the color matrix of the color I want to apply but the problem is instead of changing color of xy coordinates whole image gets colored. I don't know how to apply the colormatix to specified coordinates of the image.

I am using

matrix = 
    new float[] { 1, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 1, 0, };

imageview.setColorFilter(new ColorMatrixColorFilter(matrix));

I am looking for something like imageview.SetPixelColorMatrix(x,y,matrix)

Can anyone help me?

使用createBitmap（位图源，整数x，整数y，整数宽度，整数高度，矩阵m，布尔值过滤器）在这里，您可以指定源的坐标。有关更多详细信息，请参见this 。
