Create > Multi-page file - PDF produces blank pages

Hi Pierre,

I'm not sure if this is a bug or if I simply do not understand how this function is supposed to work.

I was experimenting with the 'Create -> Multi-page file' function. I have a series of 13 JPGs. I highlight those and let MP create a multi-page TIFF from it. Works as expected: I get a 13 page TIFF.

When I let MP create a multi-page PDF from the same JPGs, I do get a 13 page PDF. All pages are blank white, though.

Bug, feature, or user-error?

Regards
Dietmar

No problem for me for several 24-bit JPEG images saved as a multi-page PDF with JPEG compression, using XnView MP 0.89 on Linux...

Looks as if your files can't be read for some reason, could you confirm that they do open normally in the viewer, and possibly try again with some other JPEGs?

Otherwise, could you upload an example image or two?

Hi, thanks for the fast reply.
As said, the exact same JPGs transform fine into a multi-page TIFF, so I doubt this is related to the input files. Here is one of the files, anyway. Creating a multi-page PDF from this file gives me one blank page.
I'm using MP 0.90 on Linux if this matters.

no problem with your picture file, which settings do you have for PDF?

The defaults: None, None, None, and 80.

Interestingly the PDF generated from this single file is 10,2 MB in size. However, both the Ubuntu document viewer as well as GIMP show this as a blank page. Adobe Reader on Windows complains that the PDF has errors and refuses to load it.

Filesize goes down to 600k but the PDF is still faulty. See attached.

This problem is supposed to be fixed in XnView MP 0.91. Please check and confirm the bug fix here.

Hi Pierre,

I just tested this feature with the current release v0.93 64-bit on Windows 10. For the test I downloaded the example PDF provided by the OP in this thread, extracted the JPG image from it and created a multipage image in the PDF format (attached below). I confirm that the issue appears to be fixed.
