Type
With Readiris you can generate 4 types of PDF files:
PDF Image-Text. This file type is most commonly used. It contains two layers: the recognized
text, and the original image on top of the text. This way, you have both access to the recognized
text and you still see the original image.
Note: since the image covers the text, any recognition mistakes will not be visible.
PDF Text-Image. This file type is the opposite of PDF Image-Text. It contains the original image in
the background, and the recognized text on top of the image.
Note: any recognition mistakes will be visible in this format.
PDF Text. This file type contains the recognized text, but does not contain the original image of
your document. Any images in the original document are included as graphics in the PDF file.
PDF Image. When you select this file type, Readiris doesn't execute the text recognition on your
document. Your PDF file will not be text-searchable, it only contains the image of your original
document.
Version
In this drop-down list you can select which PDF version you want to generate.
PDF v 1.4: It takes Adobe Acrobat 5.0 and higher to open these documents.
PDF v 1.7: It takes Adobe Acrobat 8.0 and higher to open these documents.
PDF / A-2: Generates PDF files that are suited for long-term archiving. PDF / A-2 is based on PDF v 1.7.
PFD / A-1: Generates PDF files that are suited for long-term archiving. PDF / A-1 is based on PDF v 1.4.
Note that PDF/A is not supported with Asian languages.
Create bookmarks
Bookmarks are types of links inside a PDF document, which contain representative information about the
section they are linked to. Bookmarks give structure to your PDF documents. They are grouped in the
Bookmarks panel in the Navigation pane.
In Readiris, the option Create bookmarks creates a bookmark for each text zone, image zone and table
zone inside a PDF file.
Embed fonts
The option Embed fonts, embeds - or includes - the original fonts of your documents in the PDF file. This
way, other users will always see the documents in their original fonts on their computer, even if they don't
have the particular font you used installed on their computer.
Note that embedding fonts increases the file size of your output documents.
Optimize for fast web view
This option restructures a PDF document for page-per-page downloading from web servers. This option is
useful when accessing the documents you sent to the Cloud.
iHQC Compression
In Readiris you also have the possibility to hyper-compress your PDF documents with iHQC. 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.
iHQC is available for Image-Text and Image PDFs.
