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:

These changes are not listed in the topics below.

Event Handlers Delegates

LEADTOOLS For .NET Class Library uses the new .NET 2.0 generic event handler delegate module.

The following shows how to subscribe to an event in LEADTOOLS v.14.5 and LEADTOOLS v.15:

          // Subscribe to the Changed event of RasterImage
          myRasterImage.Changed += new RasterImageChangedEventHandler(myRasterImage_Changed)
          void myRasterImage_Changed(object sender, RasterImageChangedEventArgs e)
          {
             // handle the event
          }

              // Subscribe to the Changed event of RasterImage
              myRasterImage.Changed += new EventHandler<RasterImageChangedEventArgs>(myRasterImage_Changed)
              void myRasterImage_Changed(object sender, RasterImageChangedEventArgs e)
              {
                 // handle the event
              }

The following table lists the delegate types that have been removed in v.15:

Generic Collections

All collection types use the new .NET 2.0 generic collection module. The base RasterCollection class in v.14.5 has been replaced with a Generic RasterCollection class from which all other collection classes in v.15 derive.

The following table lists the collection classes that have been removed in v.15:

Managed Memory Images

Support for creating Leadtools.RasterImage objects with managed data has been removed. The data is now converted to an internal undefined memory allocated by LEADTOOLS. All "Managed" and "Unmanaged" memory models have been renamed "Conventional".

Unmanaged Memory Support

All methods that accept a managed array of primitive types have been overloaded with a version that accepts a native unmanaged memory buffer (IntPtr). For example, the RasterImage.GetRow method has the following overloads now:

          int GetRow(int row, byte[] buffer, int bufferIndex, int bufferCount)

              int GetRow(int row, IntPtr buffer, int bufferCount)

The following table lists all the methods that have been overloaded with a version that accepts a pointer to unmanaged memory:

Windows GDI Support

Some of the methods that accepts a .NET Graphics object have been overloaded with a version that accepts a Windows GDI handle. The following table lists all these methods:
