Hi, There is a problem with using PDFGraphics2D on the Mac , which throws an exception when setRenderingHint() is called with a certain value; the message of the exception thrown is: "null incompatible with Text-specific antialiasing enable key."
This has been mentioned on this list before, I believe. A simple fix for this would be to add a try-catch block to the setRenderingHint() method in PdfGraphics2D. However, let's assume that there is a reason not to put in the abovementioned try-catch block into PdfGraphics2D, so that this solution is inadmissible. Then, the logical solution would be for the user to extend PdfGraphics2D and override the setRenderingHint() method. However, the way PdfGraphics2D is written makes this impossible. The only visible constructor: PdfGraphics2D(PdfContentByte cb, float width, float height, FontMapper fontMapper, boolean onlyShapes, boolean convertImagesToJPEG, float quality) is package private, implying that a subclass must also be in the package com.lowagie.text.pdf Even if you create a subclass in this package, it still doesn't work, because the method create() also has to be overwritten to return an object of the subclass type, and the no argument constructor is private. Further, the create method uses a number of private variables that the subclass has no access to. A gross solution to this problem would be to change everything that's private in the PdfGraphics2D class to protected. I'm sure the developers can think of better solutions. On the other hand, if the intention is to not allow subclasses of PdfGraphics to be made, why not just mark it final? In any case, if it's hard to follow what I'm trying to say, this experiment will make it totally clear - just modify the setRenderingHint() method of PdfGraphics2D to throw an exception, and then try to create a subclass of PdfGraphics2D to work around that exception. Looking forward to your comments, SPC. ------------------------------------------------------- This SF.Net email is sponsored by Oracle Space Sweepstakes Want to be the first software developer in space?
