We released Version 2.1b of the VG.net vector graphics system. Some of the changes:

• You can now add multi-line text to any Shape in the Picture Designer.
• The ZoomToParentRectangle method was added to Picture. Use this method in conjunction with ClipRectangle to zoom a Sub Picture to a rectangle specified in the Parent coordinate space.
• The ImageZoom sample source code is provided to VG.net customers. This sample demonstrates how to use the ClipRectangle property and ZoomToParentRectangle method to zoom to selected areas of an Image.
• Several bugs with the ClipRectangle property were fixed. You can now set and resize the ClipRectangle on a Sub Picture within the designer.
• Other bug fixes and small enhancements. Please read the Readme file included in the release for more information.

There was a strong focus on the Picture ClipRectangle property in this release. What is the purpose of this property? It allows you to define a “view port” through which you can see a portion of a Sub Picture (a Sub Picture is a child Picture). The ImageZoom sample illustrates this concept nicely.

Set ClipRectangle on a Sub Picture to clip it to a rectangle specified in the Parent coordinate space. To zoom to a specific area within your Sub Picture, use the ZoomToParentRectangle method. This method modifies the Scaling and Translation properties on the Sub Picture to perform a zoom. Since the ClipRectangle is specified in the Parent coordinate space of the Sub Picture, the ClipRectangle is not affected by any transformation on the Sub Picture.
