I am trying to draw a bitmap on the screen 1" X 1.5" using this code:

Code:
    status = GdipDrawImageRectRect(graphics, image, _
                                   0, 0, 1, 1.5 , _
                                   0, 0, 192, 288, _
                                   UnitPixel)
The image draws correctly but draws to 1.3"X2"

What am I doing wrong?
