[ANN]Tcl Interface to HARU Free PDF Library

[Ohtsuka Yoshio]

Hello, c.l.t,

I am writting the Tcl interface to HARU Free PDF Library.
It is not well documented and tested yet.
But I finished to write code at first glance.
If you are interested in it, please test it.
I am happy if you send bugs or any suggestions to me.

** Features
1. Generating PDF files with lines, text, images.
2. Outline, text annotation, link annotation.
3. Compressing document with deflate-decode.
4. Embedding PNG, Jpeg images.
5. Embedding Type1 font and TrueType font.
6. Creating encrypted PDF files.
7. Using various character set (ISO8859-1~16, MSCP1250~8, KOI-8R).
8. Supporting CJK fonts and encodings.

Wow! Very nice and quick results running the demo's
on Windows XP with supplied binaries. This is obviously
a low level interface that gives wide access to PDF
capabilities. I think it will be very useful to many
people who need to package application output in a
highly portable way.

Many thanks for good work shared!

On image_demo.tcl the displayed images for "Skewing Image" and
"Rotating Image" displays look to me to be identical
to the starting image.I am using Adobe Reader 7.0 on
Windows XP. Any chance of a bug here?

Sorry, this was a bug of demo script.
Here is a patch for the bug.

I tried this package on linux redhat and it was a breeze.
I was beating my head against the wall the last days trying to find an
html -> pdf converter that support Hebrew. I tried and compiled
millions of libraries with zero result - with all of them Hebrew came
as gibberish. Today I got tcl-url and immediately tried the package.
It was of such simplicity - compile haru,png and the tcl package in 5
minutes and start working. I got hebrew text with no problem...(well
some help from ohtsuka yoshio by mail but it was my fault as I did not
look at the docs - too many days of compiling and reading docs)
amazing! such simplicity.

Yes. That fixed it.
