Hi all, I’ve done some research on curve drawing with Path etc but can’t seem to get them working together to get my desired result.
I have one path that’s drawing a curved line (working fine). Now I’m trying to use fillRectangle() in a second path to illustrate another point of data. What I’d like to have is the bottom part of the rectangle draw along the path of the line.
I tried to use addLineSegment and look at a way of filling in to the previous line segment, but that didn’t quite work either, though this shows how I’d like the bottom to curve along the line
I am not sure I understand, but a few remarks about the drawing primitives:
You can always call fillPath or strokePath. fillPath will have no effect on a path that was not explicitly closed calling closeSubPath().
cubicTo has nothing to do with a cube, it refers to the polynomial how a bezier curve is defined.
I am not sure, but you might be after using the path as a clipping region.
To do so, create a copy of your path and close it, preferably along the Component borders.
It looks roughly llike this:
juce::Path fp (curve);
fp.lineTo (currentX, 0);
fp.LineTo (firstX, 0);
fp.closeSubPath();
{
// new scope to conveniently save the Graphics state
Graphics::ScopedSaveState saveState (g);
g.reduceClipRegion (fp);
g.fillRect (whateverRect);
// end of scope restores original clip region
}
// draw the curve on top to avoid clipping by the curve
curve.strokePath (g, ...);
