Crash when using scanner


Recommended Posts

Hi:

I have a Canon TS8350 printer-scanner. If I use it to 'Acquire Image...' in Affinity Photo I can scan documents directly into Affinity. However, the box which allows me to control the parameters of the scan (resolution, image size, etc.) has an option for Image Correction. If I use this box to correct the image using the scanner software (or possibly MacOS), Affinity scans the image but then immediately crashes.

Consistent and repeatable.

Not sure if this is the same bug either, but Acquire Image doesn't work for me:

Scanning still looks OK:

The result doesn't:

No problem with Image Capture:

… and their respective results:

Does disabling Hardware Acceleration make a difference? It's a long-shot but I'd be interested to see if this is interfering with the rendering as I'm not sure if other apps use HA.

It didn't crash after I did that, but these are the results. Black and white 300dpi...

Turning hardware acceleration off makes no difference.

I get a similar result to Wilfred Hildonen, but only scanning in Black and White at 200dpi. Other resolutions, and colour scanning are fine.

However, it won't scan at all if I set the scan to 'Text': "Scanner reported an error An error occurred during scanning." No problems using Image Capture.

I have the same problem with Acquire Image when scanning from the CanoScan LIDE 400. There is no problem with the LIDE 220 scanner, it scans flawlessly. I need to use Image Capture to scan from the LIDE 400.
