* Name: nxtk_bitmaptoolbar |
|
* |
|
* Description: |
|
* Copy a rectangular region of a larger image into the rectangle in the |
|
* specified toolbar sub-window. |
|
* |
|
* Input Parameters: |
|
* hfwnd - The sub-window twhose toolbar will receive the bitmap image |
|
* dest - Describes the rectangular region on in the toolbar sub-window |
|
* will receive the bit map. |
|
* 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 sub-window coordinates, however, the |
|
* origin may lie outside of the sub-window display. |
|
* stride - The width of the full source image in pixels. |
|
* |
|
* Return: |
|
* OK on success; ERROR on failure with errno set appropriately |
|
* |
