Kind of expected that between Affinity Photo and Affinity Designer, it would be relatively simple to make a vectorized tracing of an image, similar to the result from the Adobe Capture application.
Apparently the auto-tracing feature is not yet developed for Affinity and in the forums someone recommended a command line tool called Potrace.
Install via Homebrew:
brew install potrace.
Of course I had to run
brew doctor and
brew update and before those would work, install the latest version of XCode and update the permissions on
share, maybe they changed with the OSX Upgrade.
sudo chown -R `whoami`:admin /usr/local/lib/ sudo chown -R `whoami`:admin /usr/local/share/
Potrace comes with another program that the author recommends you run first: mkbitmap, which runs various filters on bitmap files. First I need to convert to a bitmap. OSX comes with a command line util that does this called sips.
sips -s format bmp PorchChairMaster.jpg --out PorchChairMaster.bmp
Now let see what
potrace PorchChairMaster.bmp does. Not bad. Outputs an EPS file.
potrace PorchChairMaster.bmp --svg
Now let’s see what it looks like when we run
mkbitmap LloydWithBricksMaster.bmp first.
I made a bash script to automate this for me:
