Convert bitmaps to one multipage TIFF image in .NET 2.0

Question

How can i convert an array of bitmaps into a brand new image of TIFF format, adding all the bitmaps as frames in this new tiff image?

using .NET 2.0.

Answer 1

Start with the first bitmap by putting it into an Image object

Bitmap bitmap = (Bitmap)Image.FromFile(file); 

Save the bitmap to memory as tiff

MemoryStream byteStream = new MemoryStream(); bitmap.Save(byteStream, ImageFormat.Tiff); 

Put Tiff into another Image object

Image tiff = Image.FromStream(byteStream) 

Prepare encoders:

var encoderInfo = ImageCodecInfo.GetImageEncoders().First(i => i.MimeType == "image/tiff");  EncoderParameters encoderParams = new EncoderParameters(2); encoderParams.Param[0] = new EncoderParameter(Encoder.Compression, (long)EncoderValue.CompressionNone); encoderParams.Param[1] = new EncoderParameter(Encoder.SaveFlag, (long)EncoderValue.MultiFrame); 

Save to file:

tiff.Save(sOutFilePath, encoderInfo, encoderParams); 

For subsequent pages, prepare encoders:

EncoderParameters EncoderParams = new EncoderParameters(2); EncoderParameter SaveEncodeParam = new EncoderParameter(      Encoder.SaveFlag,       (long)EncoderValue.FrameDimensionPage); EncoderParameter CompressionEncodeParam = new EncoderParameter(      Encoder.Compression, (long)EncoderValue.CompressionNone); EncoderParams.Param[0] = CompressionEncodeParam; EncoderParams.Param[1] = SaveEncodeParam; tiff.SaveAdd(/* next image as tiff - do the same as above with memory */, EncoderParams); 

Finally flush the file:

EncoderParameter SaveEncodeParam = new EncoderParameter(      Encoder.SaveFlag, (long)EncoderValue.Flush); EncoderParams = new EncoderParameters(1); EncoderParams.Param[0] = SaveEncodeParam; tiff.SaveAdd(EncoderParams); 

That should get you started.
