The first "foo" is normal, but the second one is so huge I can only see the base of the "f". The font-size is the default.
BufferedImage image = new BufferedImage(500, 500, BufferedImage.TYPE_INT_RGB);
Graphics2D g2 = image.createGraphics();
Shape ellipse = new Ellipse2D.Double(0, 0, 1.0, 1.0);
g2.setPaint(Color.RED);
g2.drawString("foo", 100, 100);
g2.scale(500.0f / length, 500.0f / length);
g2.drawString("foo", 1, 1);
Changing the font size will not help because it only allows int sizes and the size that would make sense for the scale is something like 0.02.
The reason I need to draw the text while in scaled space is because I am drawing a grid of nodes and I want to scale the coordinates to the number of nodes in each dimension. That way I do not have to do complicated calculations.
I need the text to label the edges.
Update: I am able to get the text by doing the following sequence each time I want to draw the text: saving the transform, translating to the desired location in scaled space, unscaling, drawing the text at (0, 0), and restoring the transform.
You can use Font method
public Font deriveFont(float size)
to obtain desired font size font. Guess the 0.02 shoud be fine.
