svn commit: r591587 - in /xmlgraphics/fop/trunk: ./
src/java/org/apache/fop/render/ps/ src/java/org/apache/fop/svg/
Author: jeremias
Date: Sat Nov 3 03:59:09 2007
New Revision: 591587
URL: http://svn.apache.org/viewvc?rev=591587&view=rev
Log:
Completely reimplemented the PDFTextPainter. All SVG text (including flow text, but excluding special cases with filters) is now painted in PDF text primitives.
The whole thing compiles against and runs with Batik 1.6 but was developed against Batik Trunk (1.7). The TextBridge for SVG 1.2 text is omitted because we're still on Batik 1.6 and FOP wouldn't compile with it. The full feature set is only available with Batik 1.7, of course. With Batik 1.6, font selection may not work as expected.

Oh, that was a mistake. I thought I switched it to false. Thanks for
correcting it.

Ok. It’s just that I’m reluctant to modify code I’m not familiar with,
and from which I may have missed the logic.

I could do a lot of stuff. I'm so used to working pre-Java-1.4 that it
didn't occur to me. Feel free to change. There's no code-ownership in
Apache projects.

PDFTextUtil is designed to be useful for classes other than
PDFTextPainter. Someone might prefer working more closely to the PDF
spec and therefore prefer the int variant.

Again, feel free to change and improve.

No, I don't. The debug code is most probably optimized away by the
compiler so it doesn't bother us at runtime. If any bugs arise, it's
convenient to switch on. Most importantly, though, the Batik guys have
indicated that they don't want to work with a logging framework. Since
this code is destined to go to Batik I try not to introduce more Commons
Logging in this area.

Hi Jeremias,
I’d have a couple of comments regarding your changes. I’ve only had
a quick look and don’t understand this part of the code well, but
following the principle of pair review, here they are:
- at several places there is code like the following:
private void checkInTextObject() {
if (!inTextObject) {
throw new IllegalStateException("Not in text object");
}
}
I understand and don’t criticise the need for safety checks,
especially if the code is new or complex. Only, since we now have
Java 1.4 as a minimal requirement, why not use assert statements? They
were created exactly for that.
- in PDFTextUtil:
- the setTextRenderingMode(int) method is only used within
PDFTextUtil; why then not making it private? The other
setTextRenderingMode method will still be available and seems to be
much safer to use anyway.
- it seems to me that a bit more of the internal state of
a PDFTextUtil object could be controlled by the object itself,
especially in the following piece of code (PDFTextPainter, l.220):
Font f = textUtil.selectFontForChar(ch);
if (f != textUtil.getCurrentFont()) {
textUtil.writeTJ();
textUtil.setCurrentFont(f);
textUtil.writeTf(f);
textUtil.writeTextMatrix(localTransform);
}
A signalFontUsed(f) method might make sense. Basically doing the
same test as above, but inside PDFTextUtil. The code would be better
encapsulated, so more maintainable. WDYT?
- in PDFTextPainter: now that the code is working, you probably want to
remove the DEBUG variable and all the statements displaying stuff to
System.out; or replace them with proper log.debug statements ;-)
For the rest I believe when you say it’s working... Congrats!
