Creating vector graphics in JUCE

[ijijn]

Hi Geert,

What sort of vector graphics did you have in mind? JUCE has considerable support in this area; I only use vector graphics for my GUIs.

You can certainly draw simple shapes in paint() using the built-in graphics calls, such as g.drawEllipse or g.fillRoundedRectangle. The next level up is using Path objects to combine various shapes into one and/or draw polygons with an arbitrary number of vertices, which also works really well. For anything particularly elaborate I tend to use SVG assets (typically as BinaryData), loading and positioning them as desired. There are a few threads about tips and tricks for doing this kind of thing on the forum; here is one such example:

How to scale a Drawable when it's added as child component?

Let’s say a Drawable, d, is created from an SVG image, and is to be painted inside a parent component such that it is scaled to a specific area. I can draw it like this without any problems: //in paint(Graphics &g) d->drawWithin(g, Rectangle<float>(x, y, w, h), RectanglePlacement::centred, 1.0f); But I’d prefer to add the drawable as a child component instead. What would be the equivalent way of setting its bounds and transforms etc such that it produces similar results as the drawWithi…

I hope I’ve understood your request. If not, please could you clarify what you’re trying to do a little more?
