Leadtools.ImageProcessing.Core Assembly Changes from Version 16.5 to Version 17

Note on LEADTOOLS for .NET v17

In LEADTOOLS for .NET v16.5, some assemblies had a dependency on System.Drawing. System.Drawing is the .NET 2.0 assembly used with the Windows Forms and GDI+ platforms. Since LEADTOOLS v17 treats Windows Forms, Windows Presentation Foundation (WPF) and Silverlight as equal citizens, certain types in this LEADTOOLS assembly has been changed to reflect that. For example, properties with System.Drawing.Point type have been changed to use the new Leadtools.LeadPoint type, methods with a parameter of System.Drawing.Rectangle type have been changed to use the new Leadtools.LeadRect type. The following table shows the old 16.5 and corresponding new v17 types:

Old v16.5 Type	New v17 Type
System.Drawing.Point	Leadtools.LeadPoint
System.Drawing.Size	Leadtools.LeadSize
System.Drawing.Rectangle	Leadtools.LeadRect
System.Drawing.Color	Leadtools.RasterColor
System.Drawing.Drawing2.FillMode	Leadtools.LeadFillMode

New Types

The following types have been added to v17:
