Set Canvas Context2D font from local font

[twall]

Hello, I have a set of fonts that are installed locally to my development machine. They are included within my qml.qrc file. My application is a QML app that will be deployed to an embedded device that doesn't have my specific TTF font intstalled. Within my application, I have a Canvas object with a 2D context, and I'd like to apply my font there. However, when I try to use

context.font = "18px fontName";

or

context.font = "18px qrc:/fonts/fontName.TTF"

Neither appear to work on the target machine.

I can get the font to work on the target machine with Text and FontLoader. But how can I load the font into a Canvas context?
