[Aph] Guides move after cropping

[Alex_M]

Is there a way to prevent guides from moving after cropping? For example, if I place a vertical guide at 50% and then crop the image to 50% of its width, the guide will reposition itself back to 50% vertically again instead of staying at the edge of the cropped image. Does that make sense? In Photoshop if I crop the image the guides stay put and don't reposition relative to the cropped image. Let me know if I should show screenshots if you don't get what I mean.

It doesn't appear to happen on Mac, When the crop has been applied, in the Guides Manager if you click on the guide/s they change to 100% I noticed that after I'd made and uploaded this gif

Hi @firstdefence

 

You are demonstrating a very fringe case in which things appear to work normal (snapping the crop tool to the intersection point of two guides each placed at 50% of the document dimensions). This fringe case works fine here too. However, if you crop without snapping to the guides you will see the bug. Try doing the exact same thing you did in your video but this time drag the upper left corner of the crop tool to the center of the upper left box that is formed by the intersecting guides. Here's what happens when I do this (see attached below). Can you film again and post your results?

@Alex_M, maybe I have misunderstood what you want to happen, but from what I can tell from your 'before & after' screenshots, according to the rulers the guides have not moved -- in both they are at 2000 px. Your two red 'should be here' lines are at around 900 px.

Why do they move? In my daily work 99.9% of the time I want them to stay where they are even after cropping. Like in Photoshop. Do you understand what I mean? Can I do this in Photo and how?

Why does what move? As I said, from the rulers in your screenshots, the guides have not moved at all.

The guides relative to the cropping rectangle. Does that make sense or do I need to record a video?

I am sorry but I do not understand what you mean. The guides are not moving -- they are still 2000 px from the origin. So maybe you mean you want the guides to move?

[Alex_M]

Ok, it looks like this is something better illustrated than said. Thankfully I found a video that will spare me the hassle of recording one on my own. Watch from 9:47 onward. See how in Photoshop the guides stay put relative to the image & cropping rectangle?:

The guides do not stay put. They move from one point on the rulers to another, proportionally to the crop amount. It would have been a lot simpler to understand what you meant if you had just said that!

 

I don't think there is an option for that behavior in Affinity Photo but maybe someone else does.

The crop tool method for resizing in Photoshop and Affinity Photo (APh) are different.

• Photoshop keeps the crop tool static and its the image, including the guides and the rulers that move because they track the image.
• In Affinity Photo (APh), it's the Crop Tool that moves over the static image and the static guides, consequently the rulers are also static.

Visually Affinity's method is kinder to the eyes, if you scale the Crop Tool quickly in Photoshop, it sends your eyes funny, so er! don't do that.

I can't see a way to marry the two together with such polarised methods.

 

Note: When resizing an image in Affinity Photo (APh) the guides maintain their relative positions.
