RE: [iText-questions] difference between itext and fop?
iText does it the correct way. The curves you see are to make
the round end caps.
FOP actually does it the correct way, too. I'm sorry, I removed
too much of the context around the PDF generated by FOP so this
wasn't shown. The full relevant section of the PDF is:
0 G
1 J
1 j
0.5 w
10 M
1 0 0 1 0 0 cm
10 10 m
100 10 l
S
The PDF spec says:
G = set stroking color
J = set line cap
j = set line join
w = set stroke width
M = set miter limit
So, the first couple of lines actually set all the attributes
of the line that are specified in the SVG, including the round
end caps. I can't see these PDF commands anywhere in the PDF
that iText generated (I attached both PDFs for reference).
So, it seems to me that iText doesn't use some of these
commands but instead does it the manual way. Do you
if iText ever uses the commands mentioned above? And if
not, why not?
I'll dig around in the source code some more...
Best Regards,
Thomas

generation of some lines if size/performance was more important.

Subject: RE: [iText-questions] difference between itext and fop?
Ok, I figured out how to make FOP generate uncompressed
PDF and compared the output FOP and iText generate for
a very simple SVG element.
SVG:
path fill=none stroke=#00 stroke-width=0.5
stroke-linecap=round stroke-linejoin=round
stroke-miterlimit=10 d=M10,10H100/
FOP (noise removed):
10 10 m
100 10 l
S
iText (noise removed):
10 89.75 m
100 89.75 l
100.14 89.75 100.25 89.86 100.25 90 c
100.25 90.14 100.14 90.25 100 90.25 c
10 90.25 l
9.86 90.25 9.75 90.14 9.75 90 c
9.75 89.86 9.86 89.75 10 89.75 c
h
f
(The differences in y coordinates are due to differences
in the transformation matrices that are in effect.)
Is this the effect you were describing when you said:
That's because with fop for a line you'll have a width set
and a line draw and with iText it's a rectangle followed
by a fill.
Could it be due to this piece of code in class
com.lowagie.text.pdf.PdfGraphics2D?
private void followPath(Shape s, int drawType) {
...
if (drawType==STROKE) {
s = stroke.createStrokedShape(s);
followPath(s, FILL);
return;
}
...
}
It looks like it doesn't want to do STROKE, it only
wants to do FILL. What would happen if it would
allow STROKE?

RE: [iText-questions] difference between itext and fop?
FOP: batik-fop-pdf iText: batik-Graphics2D-iText-pdf I think FOP does it the same way as iText: Batik-Graphics2D-FOP-PDF Take a look at org.apache.fop.svg.PDFGraphics2D. It seems to be doing exactly the same as com.lowagie.text.pdf.PdfGraphics2D. That's because with fop for a line you'll have a width set and a line draw and with iText it's a rectangle followed by a fill. That's also because the files are bigger. I see. Is there a reason iText does it this way? That's the way Graphics2D works. iText can't do better than what it receives. Hm... given that FOP and iText seem to work the same way (through a class that implements Graphics2D), I can't see why the result couldn't be the same. It seems to me that org.apache.fop.svg.PDFGraphics2D and com.lowagie.text.pdf.PdfGraphics2D are generating different PDF content from the same Batik input. I'm going to try to find out where it happens...

RE: [iText-questions] difference between itext and fop?
Paolo, that's exactly what I'm looking for. Currently, we're doing Batik-PDFGraphics2D-FOP-PDF, but it is pretty slow. I have been wondering for a long time if hooking up iText with Batik through PdfGraphics2D would yield better results in terms of speed but didn't get around to doing it yet. All we need to do is simple black on white line art and text. I haven't used iText before, so if if you have sample code that shows how to hook up iText with Batik, I would greatly appreciate it.

Just a side note about SVG. I obtained good results with batik writing to a PdfGraphics2D. Of course that most of the psychadelic effects that are so keen to the SVG samples floating around don't work very well but FOP doesn't do much with that either.
