Enumeration Type Documentation
enum a2dCanvasObject::a2dBboxFlag [inherited] |
flags for calculating boundingbox of derived object
Those flags are used in a a2dBboxFlags to indicate different ways of bounding boxes to be calculated.
event mask flags for a2dCanvasObject hit
a2dCanvasObjectHitFlags used in a mask for defining how an object should be hit
- Enumerator:
| enum OVERLAP |
Result of a a2dBoundingBox intersection or hittest.
Function Documentation
| wxRect a2dCanvasObject::GetAbsoluteArea | ( | a2dIterC & | ic, | |
| int | inflate = 2 | |||
| ) | [inherited] |
Get absolute occupied area in the device coordinates.
The object its boundingbox in world coordinates is first translated using the matrix cworld. Cworld will normally contain the accumulated matrix to the object with in the object Tree structure.
- Remarks:
- pixel and world extend are included.
- Parameters:
-
ic iterative context to get matrix which is applied first to get to absolute position inflate extra pxiels added on each size, to get rid of double to int rounding problems.
Definition at line 3800 of file canobj.cpp.
| a2dBoundingBox & a2dCanvasObject::GetBbox | ( | ) | [inherited] |
get boundingbox in world coordinates exclusive stroke width relative to its parent
- Remarks:
- stroke width is not included.
if the boundingbox is not valid, it will be calculated right now, and to make sure parent object will have the right boundingbox, the object is set pending. That will in the update of a2dCanvasDocument, lead to redrawing and recalculation of this object and parent boundingbox will be recalculated.

| double a2dCanvasObject::GetBboxWidth | ( | ) | [inline, inherited] |
| a2dBoundingBox a2dCanvasObject::GetCalculatedBoundingBox | ( | int | nChildLevels | ) | [inherited] |
Like GetBbox, but it always calculcates the bounding box from scratch.
This is usefull, when you need the bounding box, but the stored bounding box is not up to date. The rendering system relies on doing this update on its own, because it needs the old bounding box for update area calculation.
- Parameters:
-
nChildLevels number of child levels to include (0=no childs, 1=direct childs, ...)
Definition at line 5511 of file canobj.cpp.
| a2dBoundingBox a2dCanvasObject::GetClipBox | ( | a2dIterC & | ic | ) | [inherited] |
returns boundingbox clipping object if clipping property is set
- See also:
- a2dClipPathProperty
- Parameters:
-
ic iterative context contains matrix which is applied first to get to absolute position
Definition at line 6368 of file canobj.cpp.
used for deciding if the object needs to be rendered against the current clipping area of the active drawer.
- Parameters:
-
ic iterative context contains matrix which is applied first to get to absolute position clipparent clipping status of parent object ( to optimize )
Definition at line 3874 of file canobj.cpp.
| a2dBoundingBox a2dCanvasObject::GetMappedBbox | ( | const a2dAffineMatrix & | cworld | ) | [inherited] |
first translate boundingbox with cworld and recalculate at new position
- Parameters:
-
cworld matrix applied first to get to absolute position
Definition at line 3847 of file canobj.cpp.
| a2dBoundingBox a2dCanvasObject::GetMappedBbox | ( | a2dIterC & | ic, | |
| bool | withExtend = true | |||
| ) | [inherited] |
first translate boundingbox with cworld and recalculate at new position
- Remarks:
- a2dCanvasView for the a2dCanvasDocument must be set.
- Parameters:
-
ic iterative context contains matrix which is applied first to get to absolute position withExtend if true boundingbox includes extend in world and pixels ( a2dCanvasView must be set for m_root )
Definition at line 3857 of file canobj.cpp.
| int a2dCanvasObject::GetPixelExtend | ( | ) | const [inline, inherited] |
get pixel extend
pixel extend is the amount that the boundingbox is enlarged because of the stroke its size in case of a storke with width defined in pixel coordinates. Other things may be included to get the total extend to the boundingbox of the object.
The complete area occupied by a a2dCanvasObject in general is the boundingbox enlarged with the worldExtend + the pixelExtend ( expressed in worldcoordinates ). But if needed one can add to the both extends whatever is needed.
- Remarks:
- pixelExtend is calculated while Updating document/object
a trick to be able to use objects complete in pixel coordinates, the boundingbox can be made zero while the pixel extend account for the rest. a2dHandle uses this approach. It will result in a total area that is square.
| a2dBoundingBox a2dCanvasObject::GetUnTransformedBbox | ( | a2dBboxFlags | flags = a2dCANOBJ_BBOX_CHILDREN |
) | const [virtual, inherited] |
Get boundingbox without the affine matrix transform included.
Extends as a result of stroke etc. is not included.
- Parameters:
-
flags default a2dCANOBJ_BBOX_CHILDREN to include child objects in the boundingbox
Definition at line 5475 of file canobj.cpp.
| float a2dCanvasObject::GetWorldExtend | ( | ) | const [inline, inherited] |

world extend is the amount that the boundingbox is enlarged because of the stroke its size in case of a stroke with width defined in world coordinates. Other things may be included to get the total extend to the boundingbox of the object.
The complete area occupied by a a2dCanvasObject in general is the boundingbox enlarged with the worldExtend + the pixelExtend ( expressed in worldcoordinates ). But if needed one can add to the both extends whatever is needed.
