Description:
When displaying a virtual image the display surface is smaller than the virtual image con-
tained in display memory. In order to view the entire image the display is treated as a win-
dow into the virtual image.
These functions allow an application to pan (right and left) and scroll (up and down) the
display over the virtual image.
seVirtPanScroll() will pan and scroll the current active surface.
seLcdVirtPanScroll(), seCrtVirtPanScroll(), seTvVirtPanScroll(), seLcdCrtVirtPan-
Scroll(), and seLcdTvVirtPanScroll() will pan and scroll the surface indicated in the func-
tion name.
Parameters:
x
The new x offset, in pixels, of the upper left corner of the display.
The new y offset, in pixels, of the upper left corner of the display.
