I create a new PDF and add a scanned TIFF image with:
LID := LPDF.AddImageFromStream(ImgStream, 1);
LPDF.FitImage(0, LPDF.PageHeight, LPDF.PageWidth, LPDF.PageHeight, 1, 1, 0)

The image is split into two or more separate images in the PDF.
Is there an option to prevent this?

Thanks, Harald

Hi Harald,

Would you be able to upload the image somewhere for us to take a look at it?

Cheers,

Hallo Rowan, thank you for your message.
You can find the example at http://www.officemanager.de/tmp/foren/quickpdf-split-img.pdf
Open it in Acrobat and click on the page. There are two images.
The TIFF has G4FAX compression.

Greetings, Harald

These tiffs, as mentioned in the official support area are multistrip tiff images and QPL imports each strip as creates an image for each strip. It is done this was so we can continue to use the TIFF compression used in the original TIFF file.

You would need to use a library like LibTIFF to convert a multistipped image into a single strip. Here is a link to some code that does just that.
