Several people have asked about what we have added to JPedal in the last year, and as we are moving the blog it seemed a good moment to reflect. We have a full-time development team working on JPedal so it has seen an awful lot of additions, enhancements, bug fixes and workarounds for PDF or Java issues. So here is my list of the top items we have been working on when not busy writing this blog….
1. New display modes. We now have page turning and a nifty coverflow display (think ITunes album mode). You will not be surprised to hear we have some more features planned for the next 12 months…
2. Lots of improvements in the Viewer. There is a war going on out there. Unlike most wars this is actually good news for most people as we continue to enhance our Viewer – we think it is the best and we want it to stay that way. In particular we have:-
- made it much easier to programmatically control the viewer from your code and execute commands.
- Updated search so that you can display search in a text box as Acrobat 9.0 does (you can also have all the other versions).
- Lots of additional keyboard shortcuts and mouse control via scrollwheel, etc.
2. Speed improvements. The core PDF decoding engine has been made faster.
3. Much faster JBig2 decoding. We wrote a JBig2 decoder because this has become an increasingly common way to compress image data in PDF files. We released version 1.0 under a BSD license – it has proved very popular (indeed several of our competitors use it). But it was a bit slow, so we have made it much faster. And I am afraid it is under a commercial license, so only we are using version 2.
4. Print improvements. The core printing functionality and the access in the Viewer has been overhauled. You can now preview pages, access default printers, set default printers, add listeners and lots more.
5. New Truetype font engine. We got fed up of Truetype fonts not displaying correctly if they used font commands so we wrote our own font parser to correct this. The difference is especially noticeable on Chinese and other non-English fonts which seem to make extensive use of font programs.
6. Much better documentation. The support site has been overhauled and organised into categories as well. Have a look at http://www.idrsolutions.com/java-pdf-library-support/.
7. JavaME version of the Viewer. We have produced a reduced function version of the viewer for ME.
That’s my top features – what do you think?
This post is part of our “Printing Articles Index” in these articles, we aim to help you understand printing in Java and PDF’s.
Do you need to write or read JPEG in Java?
We have an easy guide on how to write JPEG in Java using ImageIO and JDeli.
You can learn how to read/write most of the image files in ImageIO. However, it gives little control over the process.
JDeli is easy to use and offers complete support, so why don't you give a try?
