Sets the clipping rectangle for subsequent graphics operations.
Parameter
op takes one of the strings “set,” “reset,” “intersect,” or
“null”.
|
Operation |
Description |
|---|---|
|
reset |
Sets the clipping rectangle to include the entire window. The remaining parameters are ignored and can be left out. |
|
set |
Sets the clipping rectangle to the x, y coordinates with the specified width and height. Unspecified parameters default to the system window location and size. |
|
intersect |
Removed in platform.apilevel = ‘2.0’. |
|
null |
Sets the clipping rectangle to empty. All subsequent graphics commands are ignored. |
Typically
the “set” operation is called before drawing, such as for a text string. It is
important to call the “reset” operation after drawing the last clipped graphic
so that you do not leave a lingering clipping rectangle as a side effect.
Introduced in platform.apiLevel = '1.0'
