* Name: nxbe_flush
|
|
*
|
|
* Description:
|
|
* After per-window framebuffer has been updated, the modified region must
|
|
* be written to device graphics memory. That function is managed by this
|
|
* simple function. It does the following:
|
|
*
|
|
* 1) It calls nxbe_bitmap_dev() to copy the modified per-window
|
|
* framebuffer into device graphics memory.
|
|
* 2) If CONFIG_NX_SWCURSOR is enabled, it calls the cursor "draw"
|
|
* renderer to update re-draw the currsor image if any portion of
|
|
* graphics display update overwrote the cursor. Since these
|
|
* operations are performed back-to-back, any resulting flicker
|
|
* should be minimized.
|
|
*
|
|
* Input Parameters (same as for nxbe_flush):
|
|
* wnd - The window that will receive the bitmap image
|
|
* dest - Describes the rectangular region in the window that will
|
|
* receive the the bit map (window coordinate frame).
|
|
* src - The start of the source image.
|
|
* origin - The origin of the upper, left-most corner of the full bitmap.
|
|
* Both dest and origin are in window coordinates, however, origin
|
|
* may lie outside of the display.
|
|
* stride - The width of the full source image in bytes.
|
|
*
|
|
* Returned Value:
|
|
* None
