There are several ways to add pages to a TIFF file:

'We assume that GdPicture has been correctly installed and unlocked. Dim oGdPictureImaging As New GdPictureImaging() Dim ImageID As Integer = oGdPictureImaging.CreateGdPictureImageFromFile("multipage.tif") If oGdPictureImaging.GetStat() = GdPictureStatus.OK Then If (oGdPictureImaging.TiffAppendPageFromFile(ImageID, "addition.tif") <> GdPictureStatus.OK) OrElse (oGdPictureImaging.TiffSaveMultiPageToFile(ImageID, "multipageAdded.tif", TiffCompression.TiffCompressionAUTO) <> GdPictureStatus.OK) Then MessageBox.Show("Error: " + oGdPictureImaging.GetStat().ToString(), "Multipage TIFF Example", MessageBoxButtons.OK, MessageBoxIcon.Error) End If oGdPictureImaging.ReleaseGdPictureImage(ImageID) Else MessageBox.Show("Error: " + oGdPictureImaging.GetStat().ToString(), "Multipage TIFF Example", MessageBoxButtons.OK, MessageBoxIcon.Error) End If oGdPictureImaging.Dispose() |

//We assume that GdPicture has been correctly installed and unlocked. GdPictureImaging oGdPictureImaging = new GdPictureImaging(); int ImageID = oGdPictureImaging.CreateGdPictureImageFromFile("multipage.tif"); if (oGdPictureImaging.GetStat() == GdPictureStatus.OK) { if ((oGdPictureImaging.TiffAppendPageFromFile(ImageID, "addition.tif") != GdPictureStatus.OK) || (oGdPictureImaging.TiffSaveMultiPageToFile(ImageID, "multipageAdded.tif", TiffCompression.TiffCompressionAUTO) != GdPictureStatus.OK)) { MessageBox.Show("Error: " + oGdPictureImaging.GetStat().ToString(), "Multipage TIFF Example", MessageBoxButtons.OK, MessageBoxIcon.Error); } oGdPictureImaging.ReleaseGdPictureImage(ImageID); } else MessageBox.Show("Error: " + oGdPictureImaging.GetStat().ToString(), "Multipage TIFF Example", MessageBoxButtons.OK, MessageBoxIcon.Error); oGdPictureImaging.Dispose(); |
You can use the same technique as above to add a page that exists as a GdPictureImage.

As you can see in the two examples above, after adding the image we saved it and we released the image resources.

There exist overloads of the TiffAddToMultiPageFile() method, in which the TiffCompression type can be specified as well as the Compression Quality in case of TiffCompressionJPEG.
