Nisar, The Anchor patch is really only a convenience patch for multiple Math patches. e.g. for the top left corner you may use those formulas:
billboardXPosition = (-screenWidth/2.0) + xOffset + (imageWidth / 2) billboardYPosition = (screenHeight/2.0) - yOffset - (imageHeight / 2) No magic here. Regarding the column/row layout you may exchange "screenWidth" and "screenHeight" with something that fits your needs. (e.g. imageWidth*columnCount and imageHeight*rowCount) However you may post an image to show what you want to achieve?
