pixel space with a horizontal range of -1920 to 1920, and a vertical range of -1080 to
1080. This allows you to position the image so that a portion of it is displayed within the
constraints of the output raster (output resolution), or off the screen entirely.
NOTES:
• The available range of the image position depends on the horizontal and vertical
streaming resolution of the output. The image can be shifted off screen only by the
amount of the horizontal and vertical streaming resolution.
• Size and position values must be divisible by 8 (horizontal) or 2 (vertical).
Figure 31 shows the line and pixel coordinates at which you can position the image. In this
