I received a image higher my screen, and I don't know how to scroll this image. Use translate(0,y) to set the physical pixel point (0,0) to logical point (0,y). Then the canvas will start to draw at (nonexisting) physical point (0,-y) and you see the lower part of the image. Use the cursor keys to modify translation. Christian Wolf
I agree with Christian. This is exactly what I do and it works well on Nokia phones. However, it assumes that phone always displays logic coord [0,0] at the upper left corner of the physical screen. The MIDP spec did not say how the phone should display Canvases lager than the physical screen. So, this bahvaior might not be portable? I'd like to hear people's experience on other devices. Thanks.
