Hi all.
There is a requirement in our system where PDF and TIFF output must have
the same content on every page. Because of this, we need to use
identical font metrics for these two renderers.
By default, the two render differently. The widths of the fonts are
slightly different, so they wrap slightly differently, and once you have
one word wrapping to the next page, it cascades.
Anyway, I was thinking, why can't I just do this?
private class MyPDFRenderer extends PDFRenderer {
public void setupFontInfo(FontInfo inFontInfo) {
// Code copied from Java2DRenderer
fontInfo = inFontInfo;
BufferedImage fontImage = new BufferedImage(100, 100,
BufferedImage.TYPE_INT_RGB);
Graphics2D g = fontImage.createGraphics();
g.setRenderingHint(RenderingHints.KEY_FRACTIONALMETRICS,
RenderingHints.VALUE_FRACTIONALMETRICS_ON);
FontSetup.setup(fontInfo, g);
}
}
If I substitute this renderer in, then the PDF and TIFF outputs look
identical, and I can't see any noticeable problems with the PDF. As an
added bonus, it means I don't even need the XML files hanging around,
which have been a pain to manage.
So what I want to know is, is there a drawback for performing this hack?
Daniel
