you say in your document:
"Regular PDF file does not support such extra characters in basic
fonts and - according to common opinion - it's necessary to use
embedded True type fonts. This will add extra 300KB to final PDF
document."
is the 300KB number just a guess or have you verified it?
Well, it's not exact number because final size depends on the size of
used fonts. However look here
http://www.aivosto.com/vbtips/pdf-optimize.html - at the bottom of this
article there is an example of pdf with and without embedded font, the
difference is 6 kB versus 273 kB.
the use of embedded font does not, in general, include glyphs for all
characters supported by a given font, but only those used in the document;
That's right, but - as I mentioned in my article - in several countries
in central Europe we use regular Latin alphabet enhanced with some extra
characters, so it's not possible to use Base14 font for most of the text
and mix it with a few additional characters from another font, because
it will not look good. It would look like mixing characters from Arial
and Times New Roman. Hence most of embedded font will be always used.
i have a two comments and a question on your submission:
(1) you use tabs in your changes to source materials (e.g., the
Helvetica*.xml files); these need to be replaced with SPACE characters
only;
I didn't noticed that, I'm not the author of that changes. Does it make
any difference? It's just xml.
(2) to make this change only for Helvetica is sub-optimal, and will
cause interoperability problems, so all of the Base14 fonts should be
modified at the same time;
That's right. This is just a part of final solution. By the way - I'm
not sure if this mechanism works with all Base14 fonts. I used to have
problems with Courier several years ago when I implemented that solution
in another technology.
(3) does your changes to the font files include kerning data updates?
if not, then it probably should
It's hard coded in PDFFactory.java. I'm ashamed of that but due to my
limited time I was not able to find a better way to do it.
