TiffSaveAsMultiPageFile(Int32,String,TiffCompression,Int32) Method
Stores a specified GdPicture image, that is represented by its unique image identifier, as the first page of a new multipage TIFF image file to a given file path. You can also define a JPEG quality parameter when the JPEG compression is required using this method. You can subsequently add a new page to this image file using one of the TiffAddToMultiPageFile() methods, for example the
GdPictureImaging.TiffAddToMultiPageFile method.
This sequential writing is the faster way to create multipage TIFF image files by adding individual pages based on one page files.

Parameters
- ImageID
- A unique image identifier of the GdPicture image representing the first page of the resulting multipage TIFF image file. Do not release this image resource before closing the resulting multipage TIFF image file using the GdPictureImaging.TiffCloseMultiPageFile method.
Please follow the attached example on how to properly use the method.
- FilePath
- The file path where the resulting multipage TIFF image file will be saved.
- Compression
- A member of the TiffCompression enumeration. The resulting TIFF compression scheme to be used.
- JpegQuality
- The compression quality level from 0 to 100. 0 means the worst quality and the best compression, 100 means the best quality and the worst compression.
This parameter is ignored when the required compression scheme is different than JPEG.
Return Value
A member of the GdPictureStatus enumeration. If the method has been successfully followed, then the return value is GdPictureStatus.OK.
We strongly recommend always checking this status first.
Generating a multipage tiff, from different image files, using specific compression mode per page.

// After calling TiffSaveAsMultiPageFile, tiffID will specify the multipage tiff identifier.
gdpictureImaging.TiffSaveAsMultiPageFile(tiffImageID, "multipage.tif", TiffCompression.TiffCompressionJPEG, 75 /*Jpeg quality*/);
/*Adding second page from a png file*/
int imageID = gdpictureImaging.CreateGdPictureImageFromFile("image.png");
// Enabling horizontal differencing predictor mode for lzw compression.
gdpictureImaging.TagSetValueString(imageID, Tags.TagPredictor, TagType.TagTypeShort, "2");
gdpictureImaging.TiffAddToMultiPageFile(tiffImageID, imageID, TiffCompression.TiffCompressionLZW);

/*Adding third page from a single page tiff-ccitt4 file*/
imageID = gdpictureImaging.CreateGdPictureImageFromFile("image.tif");
gdpictureImaging.TiffAddToMultiPageFile(tiffImageID, imageID, TiffCompression.TiffCompressionCCITT4);
