TiffCompressOption Enumeration
Visual Studio 2008
Specifies the possible compression schemes for Tagged Image File Format (TIFF) bitmap images.
Assembly: PresentationCore (in PresentationCore.dll)
| Member name | Description | |
|---|---|---|
| Default | The TiffBitmapEncoder encoder attempts to save the bitmap with the best possible compression schema. | |
| None | The Tagged Image File Format (TIFF) image is not compressed. | |
| Ccitt3 | The CCITT3 compression schema is used. | |
| Ccitt4 | The CCITT4 compression schema is used. | |
| Lzw | The LZW compression schema is used. | |
| Rle | The RLE compression schema is used. | |
| Zip | Zip compression schema is used. |
The Ccitt3, Ccitt4, and Rle require that the PixelFormat value be set to BlackWhite. Setting the PixelFormat to any other value resets the Compression property value to Default.
The following example demonstrates how to use the Compression property.
Dim stream As New FileStream("new.tif", FileMode.Create) Dim encoder As New TiffBitmapEncoder() Dim myTextBlock As New TextBlock() myTextBlock.Text = "Codec Author is: " + encoder.CodecInfo.Author.ToString() encoder.Compression = TiffCompressOption.Zip encoder.Frames.Add(BitmapFrame.Create(image)) encoder.Save(stream)
