80 | * Pixmap Operations : (should be prepended by a colon) |
|
|
81 | * tile Tile image. Scaling/position modifiers above will affect |

|
82 | * the tile size and origin. |
|
|
83 | * propscale When scaling, scale proportionally. That is, maintain the |
|
|
84 | * proper aspect ratio for the image. Any portion of the |
|

85 | * background not covered by the image is filled with the |
|
|
