map view-window requests to codestream image resolutions and regions
- Parameters:
-
[in] | fx,fy | frame size |
[in] | rx,ry | offset of region |
[in] | rw,rh | size of region |
[in] | XOsiz,YOsiz | offset from the origin of the reference grid to the left side of the image area |
[in] | Xsiz,Ysiz | size of the reference grid |
[in] | numOfreslev | number of resolution levels |
- Returns:
- structure of image region parameters
