Ho dude, do you know that you saved a functionality of my application with this post.
As you said, we need to translate Bitmap pattern origin to our using a "setLocalMatrix()" function on the BitmapShader to translate, rotate, or even scale it. Example: Matrix localmatrix = new Matrix(); localmatrix.setTranslate(MyCanvasXCoords, MyCanvasYCoords); // a translation for example MyBitmapShader.setLocalMatrix(localmatrix); And BAM!! Is is solved. Thank you again. This post is the one of the most useful in my list of useful posts). Have a very good day, Alexander.
