cdCanvasClear(cdCanvas hCdCanvas) |
Description: |
Clears the active canvas using the current background color.
The function cdClear() is eqivalent to cdCanvasClear(cdActiveCanvas()). This action is interpreted very differently by each driver. Many drivers simply draw a rectangle with the current background color. It is not necessary to call cdClear when the canvas has just been created, as at this moment it is already clean (CD_WHITE), unless you set a different background colour. Most file-based drivers do not implement this function. |
