Method Documentation

- (DKClippingOption) clipping

Whether the rasterizer's effect is clipped to the path or not, and if so, which side.

Returns

a DKClippingOption value

- (DKRastGroup*) container

Returns the immediate container of this object, if owned by a group.

Returns

the object's container group, if any

- (BOOL) copyToPasteboard:

(NSPasteboard *)

pb

Implemented in DKStyle.

- (BOOL) enabled

- (BOOL) isValid

Implemented in DKRastGroup.

- (NSString*) label

Implemented in DKTextAdornment.

- (NSString*) name

+ (DKRasterizer*) rasterizerFromPasteboard:

(NSPasteboard *)

pb

- (NSBezierPath*) renderingPathForObject:

(id< DKRenderable >)

object

Returns the path to render given the object doing the rendering.

This method is called internally by render: to obtain the path to be rendered. It is factored to allow a delegate to modify the path just before rendering, and to allow special subclasses to override it to modify the path for special effects. The normal behaviour is simply to ask the object for its rendering path.

Parameters

object

the object to render

Returns

the rendering path

- (void) setClipping:

(DKClippingOption)

clipping

- (void) setClippingWithoutNotifying:

(DKClippingOption)

clipping

- (void) setContainer:

(DKRastGroup *)

container

Sets the immediate container of this object.

This is a weak reference as the object is owned by its container. Generally this is called as required when the object is added to a group, so should not be used by app code

Parameters

container

the objects's container - must be a group, or nil

- (void) setEnabled:

(BOOL)

enable

- (void) setName:

(NSString *)

name

- (NSString*) styleScript
