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.
