Inkscape has this function of trace bitmap and it has nice adjustments to really fint tune your graphics from jepegd/jpg and so forth. 
I've used it for color and black and white results.
Image to vector is free with Inkscape and here is the link https://inkscape.org/
This is the page about tracing...

Ahh! Thank you kindly DM1! This is very helpful and i did a cut from embedded and paste to the outer layer and this did solve my issue that was actually not an issue.
DM1 thank you.

You are working on an 'Embedded' layer. It is effectively a document loaded into your document. Double tapping is the way that Affinity 'opens' the embedded document to allow you to edit it. Using the back arrow then returns focus to your document, closing the embedded document, saving any edits you made to it.
I've  copied the embedded image and pasted into a group. You can now edit nodes while background is visible. You will need to select the layers as they are all individual curves. 🙂

Josie, this thread is regarding fonts and therefore this post is unrelated - however it's very similar to your multiple previous topics on the forums where both Serif staff and our lovely community members have offered an abundance of support.
As we've previously requested, if you're looking for help with a certain project we require you to first 'give it a go' to see how much you can create on your own, then if needed we can help with specific advice regarding the design.
Unfortunately I must ask you to refrain from creating further posts like the one above in unrelated threads as well as posts/messages regarding removing watermarks, as we cannot always provide answers to these types of questions.
We're more than happy to help if you have any particular questions or issues regarding using the Affinity app and it's tools, but the creation stage of your designs can only be achieved by yourself.

I just started using affinity designer and I was looking for the Blend Tool, because it's such an important tool in my workflow. Found this topic and now I'm a bit sad that it's been requested for over 3 years and still not there :(
