Version Changes: 16.5 to 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 have 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

These changes are not listed in the topics below.
