In my juce Application I changed circle drawings from integer precision to float as explained by jules here:
void MyComponent::paint(juce::Graphics &g)
auto area = (getLocalBounds().reduced(2)).toFloat();
area.setCentre(area.getCentre() + juce::Point<float>(deltaX, deltaY));
g.drawText("Some Text", area, juce::Justification::centred, false);
When the circle moves accross the screen, the circle moves smoothly with nice float precision, but the text jitters inside. Am I doing something wrong?
AFAIK text is quantized to the closest Y coordinate, as otherwise it would look extremely blurry. It’s a very common and unsolved problem. Even photoshop does it for fonts under a certain size.
If you still need to draw text at subpixel y positions, convert the text to a path first and then offset the path. It’ll be more blurry so you can’t use very small font sizes, but it does work.
Just in case anyone bumps into this, here is a simple example of how to achieve that:
