本文介绍了使用.NET进行BMP到TIFF格式转换的方法，通过创建Bitmap对象，设置TIFF编码参数实现黑白双色图片的转换，并提供了详细的代码示例。

bmp转tif

[vb] view plain copy print ?

Dim bmp As Bitmap = New Bitmap(f)
Dim strTifDescFile As String = "C:/abc.tif"
'黑白双色图片
Dim tifImageCodecInfo As ImageCodecInfo
tifImageCodecInfo = GetEncoderInfo(ImageFormat.Tiff)
Dim tifEncoderParameter1 As EncoderParameter
Dim tifEncoderParameter2 As EncoderParameter
Dim tifEncoderParameters As EncoderParameters
tifEncoderParameter1 = New EncoderParameter(System.Drawing.Imaging.Encoder.ColorDepth, 8)
tifEncoderParameter2 = New EncoderParameter(System.Drawing.Imaging.Encoder.Compression, EncoderValue.CompressionCCITT4)
tifEncoderParameters = New EncoderParameters(2)
tifEncoderParameters.Param(0) = tifEncoderParameter1
tifEncoderParameters.Param(1) = tifEncoderParameter2
bmp.Save(strTifDescFile, tifImageCodecInfo, tifEncoderParameters)

Dim bmp As Bitmap = New Bitmap(f)

Dim strTifDescFile As String = "C:/abc.tif"

'黑白双色图片
Dim tifImageCodecInfo As ImageCodecInfo
tifImageCodecInfo = GetEncoderInfo(ImageFormat.Tiff)
Dim tifEncoderParameter1 As EncoderParameter
Dim tifEncoderParameter2 As EncoderParameter
Dim tifEncoderParameters As EncoderParameters
tifEncoderParameter1 = New EncoderParameter(System.Drawing.Imaging.Encoder.ColorDepth, 8)
tifEncoderParameter2 = New EncoderParameter(System.Drawing.Imaging.Encoder.Compression, EncoderValue.CompressionCCITT4)
tifEncoderParameters = New EncoderParameters(2)
tifEncoderParameters.Param(0) = tifEncoderParameter1
tifEncoderParameters.Param(1) = tifEncoderParameter2

bmp.Save(strTifDescFile, tifImageCodecInfo, tifEncoderParameters)
