Re: Font Problem

Graphics2D g2 = (Graphics2D)g.create();

g2.setFont(new Font("Arial", Font.PLAIN, 12));

// set to what ever scaling factor gets the font to the right size you need.

g2.scale(0.5, 0.5);

// This position will be scaled too so you'll have to take that into account as well.

// For example, assuming the example above with a 50% scaling in both vertical and

// horizontal then a position of (100, 100) would be "transformed" to (50, 50).

g2.drawString("Foobar", 100, 100);

g2.dispose();

}

An alternative to this is to apply a transform directly to the font itself. Take a look at Font.deriveFont(AffineTransform). For the AffineTransform object you'd want something like AffineTransform.getScaleInstance(double, double) and pass that to deriveFont then use that font to do the drawing. That way you don't have to apply the scale transform to the Graphics2D object so you don't have to worry about the scaling affecting the location.

Thank you for the advice. I tried it out, here are the results

I scaled it down before I wrote to it, and it had the output described earlier.
I scaled it down AFTERWARDS, and it plain ol' didnt scale the graphics2d object!! I tried to scale it twice after painting to it, but it also did not scale after painting to it..

Thanks though!

Instead of drawing to the graphics2D and then scaling that down, try applying a scale transform to the graphics2d so that it draws the text the size you want it in the first place.

hey guys,

I actually took the time today to narrow down my problem from something that contained a large number of classes, down to 2 classes that can display the problem.

I guess at this point Im looking for a little bit of help, or is it a lot of help? Anyway, here's the issue ---

1. I write text to a graphics2d object
2. I scale the graphics2d object and print it to screen.
3. The first | marks the mid-point of the scaled graphics2d image
4. The '--Good--' designates one line of text that is printing out in the correct position - centered over the |
5. The '--Bad--' text designates the problem text - it is right aligned with the scaled graphics2d object, while it should also be centered over the pipeline - |

As a quick summary as to what is happening with the 'bad' text, the '--bad--' text SHOULD be centrally aligned to the '|', the midpoint of the scaled graphics2d object. However, what seems to be causing the issue is that I am saving the font, and re-loading it from a file. For some reason this seems to be causing the mis-alignment! But the font is picked up correctly, and it even seems to calculate the print position correctly.

Anyway, I this only happens on mac computers, and I am developing on OSX 10.3.9 with java 1.4.2.

To set this up, put the "vfn" file in the running directory of the running program. The 2 files in testMe should be part of the testMe package, and the test main class should be run.

Thanks to anyone who takes a look at this!

Thanks
