Using TiffCreateMultiPageFromGdPictureImage

[Eric]

the simple code is below :

Dim ImageID1 As Integer = 0
Dim ImageID2 As Integer = 0

oGdPictureImaging.TiffOpenMultiPageForWrite(True)
ImageID1 = oGdPictureImaging.TiffCreateMultiPageFromFile("input.tif") 'the page count of ImageID1 is > 1
ImageID2 = oGdPictureImaging.TiffCreateMultiPageFromGdPictureImage(ImageID1) 'but the page count of ImageID2 is only 1 here when i use this method
oGdPictureImaging.ReleaseGdPictureImage(ImageID1)

who can tell me what's wrong? thanks~

Hello,

The purpose of the TiffCreateMultiPageFromGdPictureImage() is to start a new editable multipage tiff from a single page.
If you need to clone a multi bitmap tiff into the memory, just brows through all pages of the input document in order to add individual pages to the destination image.

Kind regards,

Loïc
