Returns
| Type | Description |
|---|---|
| PaintContext | Returns the paint context created. |
AcquireNormalmap(Boolean, Rect, Int32)

| Rect | boundsInTerrainSpace | The bounds of the normal-map to use (in pixels). |
| Int32 | extraBorderPixels | Extra padding on the bounds specified. |
Returns
| Type | Description |
|---|---|
| PaintContext | Returns the paint context created. |
CalculateBrushTransform(out BrushTransform)
Calculates the brush transform under the cursor (taking into account scattering).
Declaration
bool CalculateBrushTransform(out BrushTransform brushTransform)Parameters
| Type | Name | Description |
