- AttachCopyToView( <Object>, <View 0|1|2> )
- If View = 0, a copy of given object is created. For View = 1 or View = 2 this command creates a dependent copy of given object whose size in given Graphics View is constant.
- Example:Let
poly = Polygon((0, 0), (1, 0), (1, 1), (0, 1))
.
If Graphics View 1 is active,AttachCopyToView(poly, 1)
creates a square with the same size at the same position.
- Note: Once the copy is created, three other arguments are added to the command definition.
- AttachCopyToView( <Object>, <View 0|1|2>, <Point 1>, <Point 2>, <Screen Point 1>, <Screen Point 2> )
- If View = 0, a copy of given object is created. For View = 1 or View = 2 this command creates a dependent copy of given object whose size in given Graphics View is transformed using the affine transform that maps Point 1 to a point whose screen coordinates (in pixels) are equal to Screen Point 1, and Point 2 to a point with screen coordinates equal to Screen Point 2.
- Example:Let
poly = Polygon((0, 0), (1, 0), (1, 1), (0, 1))
.
If Graphics View 1 is active,AttachCopyToView(poly, 1, (0, 0), (1, 1), (0, 0), (100, 100))
creates a 100px x 100px square in the top left corner of the Graphics View.
- Note: All points of the object are copied, even if they lie outside the view.
Comments
Note: All parts of <object> are mapped, even if some parts of <object> lie outside the rectangle defined by Corner 1 and Corner 3.
