Next to four types of regular PDF files, IRISDocument also offers
two types of PDF-iHQC output: PDF Image-text and PDF Image.
iHQC stands for intelligent High-Quality Compression, I.R.I.S.'
proprietary, efficient compression technology. iHQC is to images
what MP3 is to music and what DivX is to movies.

Level I compressed files are about 100 times smaller than
uncompressed images. To make full use of this compression
technology, the iHQC add-on is required.
Note that Adobe Acrobat 8 is recommended for viewing PDF-iHQC
