thx for reply did u mean font's paint? i believe it's not that the font is cannot be drawn. i think it's the position of the position 0,0 of the bitmap is not really 0,0 (it's out of bounds) because when i move the position of bitmap (bitmap.translate) with some x and y, i could see the text and text background is drawn.
