[Fixed] Large file TIFF from scanner does not load correctly

Recommended Posts

Affinity Photo 1.6.4.104/Windows 10

Am trying to load a large TIFF file from the scanner. It is a 16 bit file with dimensions 12163x15348 (see pic from Windows).  However, when loaded (apparently without error) into Affinity Photo the file size is drastically reduced to 1090x1375 (see pic from AP).

(1) This file loads correctly into Lightroom

(2) A smaller version of the TIFF file (4561x5756), also 16 bit, loads correctly into AP.

Any help would be much appreciated.

As you've shown, it loaded into the Develop Persona, which is not correct for a TIFF file. Something about that file seems to have confused Affinity Photo into thinking it's a RAW file not a TIFF file. The Serif team may need a copy of the actual file to diagnose the issue, unless they already have that problem logged.

Thank you Walt for that nugget. I didn't know that.  The smaller file (from a lower res scan) is also a .tif file and this also opens in the Develop persona.  For what it's worth I changed the file extension to .tiff but that makes no difference.  I imagine you're right that AP thinks it's a RAW file and I guess that there's a size limit for RAW files which is being hit.

If both TIFF files opened in the Develop Persona there is either something wrong with them, or with Affinity Photo's interpretation of them. You should probably attach one of the smaller files here so the Serif team can examine it. If there's anything sensitive in it you could scan something innocuous, verify that it is also not handled correctly, and upload that instead.

I have tested a small .tif file which loads into the develop persona (see pic).  It is a scan of a USAF target at low res.  The software used to create it is SilverFast Ai Studio 8.8.  In fact all scans from this software load into the Develop persona.  I have opened them with both Lightroom and other software e.g. GIMP and a proprietary TIFF editor and all open correctly without hint of a problem.  I have also attached the .tif file in the hope that someone knowledgeable at Serif (or anyone else out there) can shed some light on the matter.

Thank you once again for your help Walt.

That opens in the Develop Persona for me, too.

One interesting aspect of that file is that the byte order is "Big-endian", unlike other TIFF files I've seen that work correctly in Affinity Photo which are "Little-endian". Perhaps someone from Serif will be able to comment further. Thanks for supplying the file.

Hi Subclavius.

The issue with the opening up in Develop is because they're 16bit Greyscale TIFFs. - This is a known issue with development to be fixed. However would you be able to upload the larger Tuscany Track.tif file please so we can look into the dimensions of the image not being correct please? I've created an internal Dropbox link here for you to upload to us:

Thanks!

I purchased version 1.6.5.135 in November and it also has a similar problem.  If any TIFF that is above 1GB in size (not sure, may be close to 2GB) will cause Affinity to crash.  The TIFF load fine in Gimp and open in the windows viewer.  Not sure if this belongs in this post - should I open a new one?

realized it was a different problem

Hi BillCrum,

You should check out the latest beta release (currently 1.7.0.258) to see if you can reproduce your problem - I know that you've said it's a different problem but the beta release contains the latest updates. I can now load large files of 16bits greyscale correctly and the loading is a lot faster now.

Hi BillCrum,
Welcome to Affinity Forums :)
As Subclavius suggested please try the latest Customer Beta (Affinity Photo Windows Customer Beta - 1.7.0.284) and let us know if you still have issues. There was several improvements here and i believe the file will open correctly. If that's not the case please create a new thread and attach the problematic file so we can take a look.

Hi MEB

I downloaded the beta version and if crashes.  Just doesn't give a bug report.  Turns out there is a thread with exactly my problem that hasn't been resolved in the Bugs in Windows - so we should move my issue to that thread and I won't be monitoring this thread anymore.

Hi MEB

Just an update.  Any file, TIFF or DNG larger than 1.9GB will cause Affinity to crash immediately - not just TIFF.  Affinity crashes immediately on open - not while loading.  As soon as you hit the open button or release the file if you drag it into Affinity the program crashes.  The released version opens the bug window for a bug report but the Beta version just closes.  A TIFF file smaller than 1.5GB loads into Photo Persona - larger than 1.9GB crashes.  A DNG file smaller than 1.5GB loads into Develop Persona and larger than 1.9 GB crashes.

I should think DNG files that are very large are fairly common.  TIFF files larger than a GB are probably rare except for archive purposes.
