Crash when using scanner

[Martin S Taylor]

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.

Hi Martin S Taylor,

Thanks for the report. It looks like we have got a log of this already so I will update it with your thread.

I don't know if this is the same bug, but scanning at 200dpi doesn't work – or rather, it produces weird results which other scanning programs don't produce.

See the attached file.

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:

… or Preview:

… and their respective results:

Most definitely a bug. Trying to scan in 300 dpi black and white, using my Epson ET-2710 series combined scanner/printer, causes the entire program to crash.

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.

Thanks all. I will feed this back to the developers. Can you attach the crash reports for me too, please?

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.
