SVG in WPF

My notes on how to use SVG graphics in a WPF application


The Goal


The goal is to be able do do things like this:

    <Button Content="{StaticResource mySvgImage}">

... where mySvgImage somehow stands for a vector image that has somehow been obtained from an SVG file.  

The solution must not involve any proprietary, closed-source libraries.

Naturally, we want one of the following:

  • either directly include SVG files into our application as resources, or, if that is not possible, then 
  • have an "asset pipeline" approach where our SVG files are automatically converted during build into some format which is suitable for inclusion as a resource.

Java with Maven: Giving CI/CD a try

Please note that this is work in progress.  I am still working on it and refining it, as my understanding of it improves.

I have a set of public repositories on GitHub showcasing my work, () which is in java with maven. These projects are interdependent, so when you check out one of them, in order to compile and run it you need the binaries of some of the others. You could manually check out all of them and put them in an IDE project, but that's too much work. Solving this problem requires having Continuous Integration & Continuous Deployment (CI/CD) in place, so I decided to try my luck in setting one up using free services only.

The process involves three entities:

  • A Source Repository.  (Where our source code is hosted.)
    • I use GitHub for this.
    • Possible alternatives:
      • GitLab
      • BitBucket
  • A CI/CD provider. (Where the actual CI/CD takes place.)
    • I decided to use CircleCI for this, but in retrospect it was a bad idea, because it does not support GitLab.
    • Possible alternatives:
      • GitLab - I want to use it as a source code repository, and I don't want to put all my eggs in one basket, so I don't want to use it for anything else.
      • GitHub - I want to use it as a source code repository, and I don't want to put all my eggs in one basket, so I don't want to use it for anything else.
      • BitBucket - it is by Atlassian. Need I say more.
      • Appveyor - gives various errors like "There was an error while trying to complete the current operation. Please contact AppVeyor support." -- Lots of open source projects are using it though, so it might be worth a second try.
      • Travis CI - only works with github.
      • JFrog - overwhelmingly fancy front page followed by a not particularly fancy user experience once you get past the front page. Once I have registered, there is no way for me to log back in. 
      • semaphoreci.com - only works with github.
      • buddy.works - after you have given them your e-mail address, they tell you that it is free but they require a valid payment method.
      • atlassian.com/software/bamboo - it is by Atlassian, need I say more.
      • drone.io - not only it works with nothing other than github, they assume that I am using github, which is very annoying.
      • octopus.com - registration fails with "Please use your work email address."
      • buildkite.com - might work; not particularly user friendly.
      • codefresh.io - might work; they unnecessarily complicate things with mandatory docker images.
  • An Artifact Repository. (Where the binaries are stored.)
    • I found a place called Repsy for this; Repsy is minimalistic, unrefined, and they even have bad English on their web site, but it will do for now.
    • Possible alternatives:
      • GitHub Packages
      • GitLab Package Registry
      • JFrog Artifactory

We begin with a situation where we already have the Source Repository (GitHub) and we want to set-up the CI/CD Provider (CircleCI) and the Artifact Repository (Repsy).
