CadLib 4.0 Silverlight Version history

4.0.34.18 Jan 9, 2012:

• Rendering takes into account entity the drawing order as specified by the SORTENTSTABLE object.

4.0.34.17 Jan 9, 2012:

• Added read/write support for the SORTENTSTABLE object.
• Removed EntityColors.Black/Colors.Black as this was in reality the BYBLOCK color.
• Fixed another PDF export problem resulting in "error in page" warning.
• Draw model space when layout is the model space layout in WireframeGraphicsFactory2Util.
• Fixed problem with model space layouts not drawn.

4.0.34.16 Jan 5, 2012:

• Bug fix: line weight rendering by block/by layer were swapped.

4.0.34.15 Dec 30, 2011:

• Implemented TransformMe for DxfInsertBase.
• Moved to new Polygon2D.IsInside implementation using winding number (4x faster).

4.0.34.14 Dec 29, 2011:

• Bug fix: ACAD_TABLE entity was read incorrectly in pre R18 (2004) DXF files.
• Allowed DxfGroup to contain any handled object as member because in some files at least a DxfDictionary is referenced. This means there is no more DxfGroup.Entities property, but an DxfGroup.Members property instead.

4.0.34.13 Dec 28, 2011:

• Removed dependencies on System.Design, so CadLib can be used with .NET 4.0 Client Profile.

4.0.34.12 Dec 16, 2011:

• Bug fix: fixed LEADER color bug in case of BYBLOCK dim line color + entity BYLAYER color.

4.0.34.11 Dec 16, 2011:

4.0.34.10 Dec 16, 2011:

• Bug fix: fall back to entity color when there is no block context for the BYBLOCK dimension color (used e.g. in LEADER color).
• Fixed GraphicsConfig.UseSpatialFilters value not cloned.

4.0.34.9 Dec 15, 2011:

• Bug fix: viewport cloning failed in some cases.

4.0.34.6 Dec 13, 2011:

• Added support for spatial filtering. Support includes: * i/o for DxfSpatialFilter in both DXF and DWG. * rendering of spatial filters for both Wireframe and Wireframe2 when config.UseSpatialFilters is set to true (the default) Support includes not: * Surface rendering * easy creation of a spatial filter and assignment to DxfInsert

4.0.34.5 Dec 12, 2011:

4.0.33.56 Nov 11, 2011:

• Added methods to add/remove drawables from SurfaceGraphicsCache and WireframeGraphics2Cache.

4.0.33.55 Nov 11, 2011:

• Bug fix: calculation of DxfText.AlignmentPoint1 from AlignmentPoint2 was incorrect for non-horizontal text.

4.0.33.54 Nov 10, 2011:

• Added SurfaceGraphicsCache class (similar to WireframeGraphics2Cache).
• Bug fix: updating drawables in WireframeGraphics2Cache didn't work properly.
• Simplified ISurfaceGraphicsFactory a little (removed entity and draw context parameters where not necessary).

4.0.33.53 Nov 8, 2011:

• Bug fix: HATCH entities with a boundary path consisting of just 2 line segments should not be rendered.

4.0.33.52 Nov 7, 2011:

• Bug fix: SvgExporter wrote heigth instead of height.

4.0.33.51 Nov 5, 2011:

4.0.33.49 Nov 1, 2011:

• Bug fix: reading transparency from DXF was incorrect.
• Used WireframeGraphicsFactoryUtil in WriteableBitmapExGraphics3D (Silverlight).

4.0.33.48 Oct 30, 2011:

• Added GDIGraphics3D.CreateGraphicsFactory() method so a user can make direct calls to the graphics factory. This way he can create his own wrapper graphics factory and do something special for certain entities. Can use in conjunction with WireframeGraphicsFactoryUtil.
• Added example solution for new WpfWireframeGraphics3DUsingDrawingVisual class and WireframeGraphics2Cache.

4.0.33.47 Oct 28, 2011:

• Added WireframeGraphics2Cache.UpdateDrawables method.
• Added a WireframeGraphics2Cache that caches drawables created using the IWireframeGraphicsFactory2 interface. This helps to speed up recreating WPF drawables when a Canvas is resized.
• Added properties to access insert transformations or made them public.

4.0.33.46 Oct 23, 2011:

• Bug fix: rectangle zoom in Silverlight WPF rendering didn't display the correct rectangle.

• Added win forms drawables for the rect zoom/rotate interactors.

4.0.33.40 Oct 18, 2011:

• Bug fix: DXF writing of XRECORD crashed for certain groups in some cases. Made POINT3D group handling more consistent between DXF/DWG related code.

4.0.33.37 Oct 9, 2011:

• Made a few bug fixes in the SelectAndTransformInteractor and the updating of entity drawables in GDIGraphics3D.
