Resizing images

Post by Martin Mouse »

Windows 11, PaintShop Pro 2023 Ultimate
When resizing upwards, PSP defaults to AI-powered and, even with my brand-new high powered laptop, a resize can take up to 5 minutes !!!
Bi-cubic is fine for my purposes and very quick - how can I stop PSP from choosing AI ?
I know I can do this manually every time, but that is a pain.
Thanks
Martin

Thanks. Is that the only option - I have never tried scripting ?

How big is your image and how big are you making it that it takes 5 minutes? Does your high-powered laptop have a dedicated GPU you can turn on GPU support? GPU support tends to go faster than just CPU AI resizing. But I acknowledge that doesn't answer your question

I don't believe there is a way to stop it from happening altogether. PSP does it to be "helpful". It's a design choice. Scripts are your best bet but there is a small niggle there as well.

I just tried some scripts, and PSP always defaults to AI so long as the dialog shows up even if you expressly identify bicubic as the resample mode. Which means the only scripts that can avoid this are the ones that don't show the resize dialog and just resize. So if you resize by the same amount every time, a script can save you quite a bit of time as it'll work just like a preset. One press and it runs and you're done. But if you need to change things, that gets a bit harder. It can still be done of course.

Thanks for the response. Now that I know the cause of the slowness, I am coping by remembering to change the setting to bicubic, which seems to be good enough for my purposes, when I upsize.

The images are generally 6000 x 4500 pixels. Taking this as an examples, here are the resize times, for a 50% increase in pixel dimensions, with nothing else running on the PC . . .
Bicubic: too fast for me to measure
AI with GPU unchecked: 14 minutes 38 seconds
AI with GPU checked: 4 minutes 2 seconds

Sadly I do all sorts of different resizing - luckily most of it is downsizing for which PSP does not default to AI-powered.
