- Some speed improvements
- Added support for mixed compression in Multipage TIFF image *

* Mixed compression in Multipage TIFF images. How does it work ?

It is now very easy to mix compression in Multipage TIFF images to get reduced file size.
The idea is very basic: Bitonal (black & white) frames are compressed using CCITT4 scheme & other frames will use LZW compression.
To use this feature you have just to use the new TiffCompressionAUTO member of the TiffCompression enumeration into appropriated methods.

- Example using the sequential tiff image writing method

Code: Select all

    ' Create multipage tif image from several existing image files:
    Dim ImageID1, ImageID2, ImageID3 As Integer
     
     ImageID1 = oGdPictureImaging.CreateGdPictureImageFromFile("image1.tif")
     ImageID2 = oGdPictureImaging.CreateGdPictureImageFromFile("image2.jpg")
     ImageID3 = oGdPictureImaging.CreateGdPictureImageFromFile("image3.jpg")
     
     oGdPictureImaging.TiffSaveAsMultiPageFile(ImageID1, "multipage.tif", TiffCompression.TiffCompressionAUTO)
     oGdPictureImaging.TiffAddToMultiPageFile(ImageID1, ImageID2)
     oGdPictureImaging.TiffAddToMultiPageFile(ImageID1, ImageID3)
     oGdPictureImaging.TiffCloseMultiPageFile(ImageID1)
     
     oGdPictureImaging.ReleaseGdPictureImage(ImageID1)
     oGdPictureImaging.ReleaseGdPictureImage(ImageID2)
     oGdPictureImaging.ReleaseGdPictureImage(ImageID3)

Enjoy !
