  • Rectangles
  • Ellipses
  • Text
  • Polylines
  • Polygons
  • ...and others
• Vector object appearance (color, fill) can be modified in run-time.
• Extensible architecture - you can create any custom objects you can imagine.
• All objects (both images and vector objects) can be moved, resized, rotated, skewed. Resize can be proportional or arbitrary. Certain operations can be disabled (e.g. you can allow to move and resize, but disallow to rotate, etc).
• Multiple layers can be added to the control. Each layer can hold multple objects.
• Layers can be easily hidden, swapped or removed.
• All objects on the control can be easily merged into a bitmap.
• The content of the control can be serialized and deserialized (i.e. saved to a file, and then restored).
• ...many other handy features are available in the control.

Aurigma.GraphicsMill.WinControls.ThumbnailListView control has been improved:

• Support of a huge number of items.
• Possibility to specify a work area for the ThumbnailListView. This way you can manage the flow of the items inside the control (e.g. have items to flow horizontally).

• Animated GIF optimization:
  • Crops out those part of the frame which are equal to previously added frames (depending on disposal method).
  • Uses global palette whenever possible.
• Possibility to implement custom codecs to load and save files of your own file formats. Now you can easily make it closely integrated into Graphics Mill for .NET. In particular, you will be able to load and save files of your custom file format through Bitmap.Load and Bitmap.Save methods, run these operations asynchronously through Graphics Mill for .NET (no need to implement asynchronous support by yourself), etc.
• Possibility to preserve transparency when converting bitmap with alpha channel to indexed pixel format.
• New class Aurigma.GraphicsMill.MultiTaskManager which enables you to build a chain of transforms and codecs and run them as a single operation with a through progress and other events.

• ...a number of various minor bug fixes.

Miscellaneous

• GDI cannot handle bitmaps with an alpha channel when it draws anything on it. As the high byte of 4-byte color must be zero in GDI, each pixel drawn with GDI becomes transparent. So now, if you try to call any drawing methods for the bitmaps with an alpha channel when using GDI, the UnsupportedPixelFormatException exception will be thrown.

• Optimized the Aurigma.GraphicsMill.Transforms.AdjustHsl transform speed.
• Fixed the problem with multithreaded environment on multiprocessor machines.
• Fixed the problem with GDI resource leak in the trial version of Graphics Mill for .NET under heavy load. Note, full version of Graphics Mill for .NET did not suffer of this bug.
