Hi. Mac user here. I am trying to crop a section from a larger image. I have found that no matter what I do, I can NOT get my crop to be exactly what I selected:

Failed method 1: "new from clipboard". When I use the Rectangular Marquee Tool to select a part of the original image (see screenshot),299943173_ScreenShot2021-11-15at3_43_16PM.thumb.png.8f9d81755bb2dcfa9c80e9b2dcc7cb80.png then hit Command+C, then File -> New From Clipboard, it makes a new image with excess information (see screenshots).

This excess information is carried over to when I try to manipulate the image in Affinity Designer and is unmanageable.

Failed method 2: crop original file, then export as PNG file WITH "selected area only" clicked. When I do this, it saves the dimensions of the entire image, not just the selected area. If I save the original file, it adds extra information as above.1077903921_ScreenShot2021-11-15at3_46_52PM.thumb.png.6d06809e1ac75bd1f836d65a588ca05f.png

I have found that these issues have only just happened, I think with the recent upgrade of the software.

My IDEAL solution would be that the new from clipboard would work perfectly, that way I can drag the bounding box to the next set of bands and the images will be the same size, but I can't have that extra information. I'm pulling my hair out on this one.

Any help would be greatly appreciated!

Do you have only the one layer in the original document?

Are you using Designer, Photo or Publisher?

What file format is the image (PNG, TIFF, PDF, PSD...), and is it a Pixel layer in the original document?

Mac Pro (Late 2013) Mac OS 12.7.6 
Affinity Designer 2.5.7 | Affinity Photo 2.5.7 | Affinity Publisher 2.5.7 | Beta versions as they appear.

I have never mastered color management, period, so I cannot help with that.

Looks Ok to me, it took over your pixel selection, what is there "excess information, what do you mean with that?"

The above copied image portion looks to be bitmap/pixel, so in Designer you would probably have to switch over to the Pixel Persona in order to make any use out of that. - And if the selection (marching ants) is also taken over (which I doubt, but who knows ?) then you would have to dismiss it first, before being able to make any changes/manipulations in the Pixel Persona.

For the export, selection means there selected layer objects and not Rectangular Marquee Tool selections. For example if no layer is selected, but you have a Rectangular Marquee Tool selection, the export dialog usually doesn't give/show you a choice to export only the selection then (since there is then actually no layer selection). - Selections in that export context are always layer based object selections.

Alternatively you can draw a rectangle with the Rectangle Tool to use it as your selection. Don't assign stroke or fill (or place its layer behind/below the image/pixel layer). With only the rectangle layer selected export this Selection Area. It will export anything currently visible within the selected area, regardless of its layers.

this seems to have worked, although quite a hassle... do you know how i can change the name of the exported image?

honestly, replaced Adobe with this software is NOT easy... so many extra hoops to go through. wish the devs would make it easier to do things like this.

yes, that exactly. for some reason, it is making the selection larger than what i originally selected.

Which is why I asked about layers and file format.

sorry, let me answer these questions. i am using photo for the cropping (although would much prefer to use designer, as i have to organize the images there anyway)

yes, only one layer - although i need to rotate the original image some (wish i could do that by specific degrees, instead of 15 degree implements)

file format is TIF. not sure what is meant by Pixel layer

A FX

Certain FX's (even if invisible) will affect the copy and paste, making the pasted image look bigger 

We would need to see the document to see exactly what could be happening

I can't reproduce this yet. – Can you upload your Affinity document with this pixel layer before copy/new?

You get asked to name the file during the export process. Or can rename afterwards in the finder/explorer.

Hi. Here is the original image. And yes, thanks about the naming thing, I swear it wouldn't let me do it before.

Do not rotate and try again.

If you are going to be doing a lot of this sort of thing you need to know that a Pixel Layer's pixel information is not going to be automatically selected just because there is a marching ants selection. The actual Pixel Layer must be selected in the Layers Panel in order for its pixels to be copied. You could have a completely different pixel layer selected and thus copied compared to what is visible.

A Marching Ants selection is simply an area, not necessarily pixel information in that area.

Any Selection can be saved as a Spare Channel for reuse.

so... what do you suggest as the best/easiest option?

I would do all the work on a Photo Document and after rotating I would Flatten the document by using the Document > Flatten menu command. this will give me a Pixel layer. Then make my selection and Copy then make a new document via File > New from Clipboard. Export however you want.

I assume you have the TIFF files saved somewhere, I would keep them and delete my Affinity Documents if all I wanted was the selections.

this seems to work, in fewer steps than using the export portfolio option. thanks a bunch.

How did you transfer this .TIF into Affinity?
To me your .tif opens as pixel layer & "New From Clipboard" of such a selection works without an additional area or transparency.
