Question

Opening a PDF in Photoshop and file gets distorted

Opening any PDF file bigger than 106.666" wide or tall Photoshop automatically squishes the file back to 106.666". A work around is creating a PSD file at the same size as your PDF and then placing the PDF within. Comes in at 100% no issues. 

My question is why is there a size limit when opening a PDF in PSD? Should Photoshop not issue a warning if it is going to create a distorted file?

Photoshop has a pixel limit of 300k, not 30k. Not sure why you'd run into an issue with 107" documents unless the dpi results in a higher pixel count than Photoshop will work with.

 

I'm not able to reproduce on my end.  I created a PDF that is 110" wide and was able to place it into a document which was 115" wide and it came in without issue. I used a DPI of 300. 

 

Can you share your PDF so I can test on my end?

@BrettN – thanks for joining the discussion.

 

Yes, however, I was basing my comments on where this issue was previously reported when rasterizing a PDF file and it was determined that anything over 30K 32K pixels in width or height resulted in distortion.

 

I'll see if I can find the old topics where this came up.

 

Rasterizing a PDF at a width or height that is greater than 30K and placing a PDF into an open file larger than 30K on the width or height may invoke different processing. Or perhaps this is just something that was fixed in later versions and is just a coincidence that 30K and 300K pixel dimensions were historically important in Photoshop.

Photoshop rasterises generic PDF input. There is a 30,000 px 32,000 px limit, otherwise, distortion occurs.

I wish two things, well, three really. If there is a 30,000 px limit Photoshop should either (1) not open the file or (2) provide a warning that distortion will occur. (3) not have a limit on opening files sizes because Photoshop allows creation of new file bigger than 30,000.

While we ponder, BSH, note that as far (not very) as I understand, one can't save as PDF. "Photoshop PDF." Here is one site's discussion:
