| Returned value: |
| * function does not return value |
| Remarks: |
| * There is no checks for correctness. The setting of too large |
| values will result that the background will contain data abroad |
| of buffer for the background image. Buffer size = 0x160000-0x10, |
| that corresponds to maximum size 800*600. (800*600*3=0x15F900) |
| * Before calling functions 15.2 and 15.5 you should call this function |
| to set image size! |
| * For update of the screen (after completion of a series of commands |
| working with a background) call subfunction 3. |
| * There is a pair function for get size of the background image - |
| 515,7 → 513,7 |
|---|
| Remarks: |
| * Offset for a pixel with coordinates (x,y) is calculated as |
| (x+y*xsize)*3. |
| * If the given offset exceeds 0x160000-16 = 1.375 Mb - 16 bytes, |
| * If the given offset exceeds size sets by function 15.1, |
| the call is ignored. |
| * For update of the screen (after completion of a series of commands |
| working with a background) call subfunction 3. |

| Returned value: |
| * function does not return value |
| Remarks: |
| * If the block gets out abroad 0x160000-16 = 1.375 Mb - 16 bytes, |
| * If the block gets out abroad size sets by function 15.1, |
| the call is ignored. |
| * Color of each pixel is stored as 3-bytes value BBGGRR. |
| * Pixels of the background image are written sequentially |
