Multiple images in memory

[steves]

Hi is it possible to extract multiple pages from a pdf into a multiple page image in memory without saving it to a file first.

For example

Code: Select all

 For i As Integer = 1 To Me.Viewer.PageCount        ' 4 pages
            nImageid = Me.Viewer.PdfRenderPageToGdPictureImage(200, i)
            image.ConvertTo1Bpp(nImageid)

-->> need some thing here like image.copy(nimageid,nImageid2,i) ' (Source image , dest image,page number)
           
 Next

Me.Viewer.DisplayFromGdPictureImage(nImageid2) ' displays all 4 pages

Thanks
steve

Hi Steve,

Just create a multipage tiff image using the GdPictureImaging class. You have several samples into the documentation & into the forum.

Let me know if you need more assistance.

Kind regards,

Thanks Loic thats just what i was after.
I was assuming that i would need to save the multipage tiff beofre being able to view it and didnt realise i could do it in memory.

Many thanks for the swift response.

Cheers
