fprime-visual --source-dir examples/
Ctrl + C will stop the application.
You can change the look of FPV by selecting one of the themes residing in the flask/static/js/themes directory. Themes can be selected with the following argument
fprime-visual --theme dark
A screenshot button in the top banner allows for capturing a screenshot of the current view as a PNG image.
Theme colors use RGBA (RGB color values with an Alpha channel). The alpha channel is particularly important for the component box backgrounds. Connection lines occasionally route behind component boxes, so an opaque percentage value of 80% (.8) on those boxes is strongly encouraged.
Example: backgroundColor: "rgba(61, 61, 61, .80)"
You can make more intensive changes, such as connection line width and column width, by editing the config variable at the top of the public/js/canvas.js file.
