Hi folks,

short question from a beginner (couldn't find an answer via the search function)

I want to outline some cells in an image, and and make the border e.g. 0,25 mm and in green colour. Important: I don't want to make it pixelwise (cause I dont want a "cubic" appearance a la minecraft of the outer line)

Here you can see an image I would like to select and outline a few of the cells (& make the border in color).

In general I find it hard to make some figures for scientifc need (am I the only one or is there some course for this affinity related?)

Thank you guys in advance!

Thank you very much @GarryP!! 

But one question I don't wanted to use the pixel persona...you can still see in your example the pixelated border: I want to make it antialiased! Do you know what I mean? Can I probably convert it into a vector?

Ah, I see, you want the outline as a vector.
In that case you can use the Pen Tool and Corner Tool to get what you want quite quickly, see attached video.
In my video I’ve created the outline very quickly but you will get better results if you take more time over where you place the nodes.

Ahh thank you very much @GarryPfor this detailed tutorial! This helped me alot!

Nice to have persons like you in this community to help "newbies" like me! :)

 

e: just one last question: ist it possible to make the vector you made a bit "smoother"? No hard "corners", more like a "floating" outline. You understand what I mean?

You’re welcome.

Unfortunately I don’t know what you mean by “no hard corners” or “floating” so it’s difficult to give precise advice.
One suggestion would be to add a Gaussian Blur Effect to the outline but that would make the outline come out as a raster when exported.
Another suggestion would be to use an Outline Contour Effect but that would also be rasterised on export.
If you can give us a visual example of what you want then we should be able to advise better.
