|
| 9 |
Added some overlay and backdrop functions |
| 10 |
for vector games. Mathis Rosenhauer - 10/09/1998 |
| 11 |
|
| 12 |
MAB - 09 MAR 1999 - made some changes to artwork_create |
| 13 |
MLR - 29 MAR 1999 - added disks to artwork_create |
| 14 |
MLR - 24 MAR 2000 - support for true color artwork |
| 15 |
MLR - 17 JUL 2001 - removed 8bpp code |

overlay_create |

|
| 957 |
This works similar to artwork_load but generates artwork from |
| 958 |
an array of artwork_element. This is useful for very simple artwork |
| 959 |
like the overlay in the Space invaders series of games. The overlay |
| 960 |
is defined to be the same size as the screen. |
| 961 |
The end of the array is marked by an entry with negative coordinates. |
| 962 |
Boxes and disks are supported. Disks are marked max_y == -1, |
| 963 |
min_x == x coord. of center, min_y == y coord. of center, max_x == radius. |
| 964 |
If there are transparent and opaque overlay elements, the opaque ones |
| 965 |
have to be at the end of the list to stay compatible with the PNG |
| 966 |
artwork. |
