TileMode Enumeration
Describes how a TileBrush paints tiles onto an output area.
Assembly: PresentationCore (in PresentationCore.dll)
| Member name | Description | |
|---|---|---|
| None | The base tile is drawn but not repeated. The remaining area is transparent | |
| Tile | The base tile is drawn and the remaining area is filled by repeating the base tile. The right edge of one tile meets the left edge of the next, and similarly for the bottom and top edges. | |
| FlipX | The same as Tile except that alternate columns of tiles are flipped horizontally. The base tile itself is not flipped. | |
| FlipY | The same as Tile except that alternate rows of tiles are flipped vertically. The base tile itself is not flipped. | |
| FlipXY | The combination of FlipX and FlipY. The base tile itself is not flipped. |
This example shows how to use the TileMode property of a TileBrush to create a pattern.
The TileMode property enables you to specify how the content of a TileBrush is repeated, that is, tiled to fill an output area. To create a pattern, you set the TileMode to Tile, FlipX, FlipY, or FlipXY. You must also set the Viewport of the TileBrush so that it is smaller than the area that you are painting; otherwise, only a single tile is produced, regardless which TileMode setting you use.
The following example creates five DrawingBrush objects, gives them each a different TileMode setting, and uses them to paint five rectangles. Although this example uses the DrawingBrush class to demonstrate TileMode behavior, the TileMode property works identically for all the TileBrush objects, that is, for ImageBrush, VisualBrush, and DrawingBrush.
The following illustration shows the output that this example produces.
