When using Canvas.drawBitmap() with a src and dst Rect, are the edges considered inclusive? Presumably the left and top edges are, but I am unsure about the right and bottom edges. Consider the following:
Rect src1 = new Rect(0, 0, 0, 0); Rect dst1 = new Rect(1, 1, 1, 1); cv.drawBitmap(bm, src1, dst1, null); Rect src2 = new Rect(0, 0, 1, 1); Rect dst2 = new Rect(1, 1, 2, 2); cv.drawBitmap(bm, src2, dst2, null); Which of the two examples above blits a 1x1 pixel rect from the upper- left corner of bm to the second row/col pixel of cv? Presumably, one of them does. More to the point, if the right and bottom edges are inclusive, then the following is an error, correct?: //Blit lower right subRect to an arbitrary location Rect src = new Rect(x1, y1, width, height); Rect dst = new Rect(x2, y2, (width - x1), (height - y1)); cv.drawBitmap(bm, src, dst, null); If the edges are inclusive those blits read from off the right/bottom edges of bm and write an extra row/col of pixels on the right/bottom of the dst rect into cv? In which case the correct usage would be to replace width with (width - 1) and likewise for height. So, which way is correct? How are the edges of the Rects interpreted?
