Hello, I am evaluating v14 ActiveX. How can I save a multi-page image to a PDF file? I thought I'd be able to do it using the .SaveToFile method of the ImageList control. It is giving me an error.

Thanks.

Hello,

What is the exact error that you got when trying to save multi-page image to PDF file format?
Can you add a code snippet that shows how exactly you are saving to PDF forma?

However, the following code shows how to save a multi-page TIFF file to a Multi-page PDF file by using LEADTOOLS OCX programming interface:
+------------------------------------------------------+
i = LEAD1.Load("j:\images\fax1.tif", 0, 1, -1)
For i = 0 To LEAD1.BitmapListCount - 1
LEAD1.BitmapListIndex = i
LEAD1.Save "c:\testtest1.PDF", FILE_RAS_PDF_G4, 1, 2, SAVE_APPEND
' LEAD1.Save "c:\test2.tif", FILE_TIF, 1, 2, SAVE_APPEND
Next i
+------------------------------------------------------+

Thanks,

Maen, thanks for your reply. I have since switched to the Raster COM object but still no luck. My code is this:

    intBitmapBits = GetBitmapBits()   '-- get color bits

    If intBitmapBits = 1 Then    '-- black & white
        intFormat = FILE_RAS_PDF_G4
    Else
        intFormat = FILE_RAS_PDF_JPEG
    End If

LEADRasterImgList1.SaveToFile strFileName, intFormat, intBitmapBits, 0, False

I get:

? error
LEAD Error: Invalid file format
? err

Thank you for contacting LEADTOOLS. The Imagelist control does not support saving out to all of our formats. if you would like to save as PDF, you should use the main raster object.

dim io as new LEADRasterIO

i = io.Load LEADRasterView1.Raster, "c:\images\multi.tif", 0, 1, -1

For i = 0 To LEADRasterView1.Raster.BitmapListCount - 1
LEADRasterView1.Raster.BitmapListIndex = i
io.Save "c:\testtest1.PDF", FILE_RAS_PDF_G4, 1, 2, SAVE_APPEND
Next i
