API Changes (from previous version)
Note: There are quite a few API differences between this version and the previous one. One reason is that Qoppa’s libraries are now compiled in Java 6 and make use of Generics. The other reason is that many methods that used to be accessible through IPDFDocument and IPDFPage have been copied to PDFDocument and PDFPage to make these methods more visible to our customers.
It is important to bring the new jars into your IDE and to recompile your application when upgrading to the new version of our libraries.
- Change Java version to 1.6
- Change API to use generics. This requires to bring new jars into IDE and recompile.
- Much improved up-sampling of images
