And on other methods you'll see, e.g., not two but four 'drawString()' overloads that, like the 'drawImage()' overloads, do not bother with naming the method differently. That "F" wart in the name 'drawImageF' is not necessary. Also, it is not compliant with the Java Coding Conventions. Some argue against overloads. I say use them if they suit. One place they do not is factory methods. -- Lew
