Can someone tell me how to make the drawImage to be the origin size
of the source picture?
I'm not sure if it's the problem in your case, but a common mistake
is to assume that a bitmap image will automatically and always be
displayed at screen resolution. A bitmap image loaded from a file can
have a resolution that differs from the one used by your monitor, and
when displayed the image would in that case appear smaller or larger
than would be expected from looking at the bitmap pixel dimensions
alone.
