I loaded the first bitmap (image1) on the canvas i.e. sized 320 X 312. The second bitmap (image2) is 41 X 41 loaded at x,y - 235, 147. Overlapped on top of the image1. Now when I do a draw line from x,y - 174, 254 to x,y - 249, 177 in the touch event. The lineTo destination 249, 177 is "underneath" the image2 drawn at 235,147 thus the last 14 or so pixels of the drawn line is hidden under image2. I hope I explained this clearly. How do I get the full line length to show?
