Affinity Designer or Photo has no option to trace bitmaps into a vector curve. We can use the opensource application Inkscape for this, but usually when you have low resolution bitmap, the trace results are very unsatisfactory.
In this video, i'll show you a trick you can apply to get better results in Inkscape by utilising Affinity Photo or Designer.
This trick works best for logo style images with a clear and simple outline.
I hope you like the video and thanks for watching.
