Unknown Blue Line On Image

[Tar]

Hi all,

I can't think of anything I did to make this line appear on my image. I've tried switching all the layers off and on to see if it was on one of them, but no joy in removing it so far. At first I thought I might have something highlighted - like a rectangle layer - but that's not the case.

Thanks for any ideas.

Hi,

this line is probably a ruler. You can manage them with the view menu (show rulers, or the managers to delete them).

Another option is that you activated snapping, and „show snapping candidates“.

HI @Tar,

This looks like a guide that you may have placed previously.
You can either hide it: "View", uncheck "Show Guides", or remove it: "View", "Guides Manager".

EDIT:

I had not read the answer of @NotMyFault, my answer is double, sorry!

Many thanks for the quick response. Looks like I've pulled a ruler guide down without realising. Ah well, I've learned something new.

You're welcome!

I'm sure this is obvious now, but technically, it would be a guide, not a ruler.

Technically, it's a Ruler Guide.

Actually, the line, guide, rulers name is Horace Zontal.

The History panel just calls it a guide, not that that means much.

There is also more talk about "Guides" in the referenced Help. The term Ruler Guides is only an attempt to distinguish it from Columns Guides.

A simple way to determine if some odd line, or other unwanted effect, is actually part of the image, as opposed to just seeing it  on screen in the app, is to export it and see if it is still there in the exported image, 👍

...or simply turn off the image layer.

True, as long as there's just a single image layer; could be more of a problem with lots of layers and effects etc. As the OP said, "I've tried switching all the layers off and on to see if it was on one of them, but no joy in removing it so far." So he assumed it was still there, somewhere, and didn't realise it was just a ... (no, I'm not going there!)

Yes, and that's a complaint I have about the Help in general. If you look at Help topics about Text Styles, for example, I have found some spots that talk of Styles, where they really mean Text Styles.

There's a general inconsistency that can cause confusion.

Of course, with Guides we get that inconsistency between the Help and the menus, too, since the menus refer to Guides and to Column Guides, but not to Ruler Guides.

In addition to consistency (which should be a matter of course), Help would also benefit from greater clarity and comprehensiveness, as it is a basic source of information about Affinity applications and its features for many users. Although there are a lot of videos, for non-English speaking users are difficult, and written tutorials is scarce.
