DjVu Converter

Monday, July 19th, 2010

The electronic DjVu format is becoming more and more popular. It is intended for storage of scanned documents (forms, electronic books and so on). DjVu is positioned as an alternative to the PDF format. An advantage of DjVu is the lighter size of the DjVu files in comparison to PDF file sizes.
Two Pilots has released a new freeware product for creating DjVu documents. DjVu Printer Pilot is an application based on a virtual printer. After installation of the program, the <DjVu Printer Pilot> virtual printer will be installed in your system. Now you can “print to” this printer any document you wish to be converted into DjVu. While printing, the document is automatically opened  in the DjVu Printer Pilot window. From here you can save the converted DjVu document or combine it with another document created earlier.
For DjVu creation, the DjVuLibre free library is used.

PDF/A is a format for long-term preservation

Monday, June 7th, 2010

PDF/A is a electronic document file format for long-term preservation. Standards to address the growing need to maintain information in electronic documents over archival time spans. The feature-rich nature of PDF can create difficulties in preserving information over the long-term, and some useful features of the PDF file format are incompatible with the demands of long-term preservation. For example, PDF documents are not necessarily self-contained, drawing on system fonts and other content stored external to the original file. As time passes, and especially as technology changes, these external connections can be broken, and the dependencies cause information to be lost.
The PDF/A-1 standard is based on Adobe’s PDF Reference 1.4, and specifies how to use a subset of PDF components to develop software that creates, renders and otherwise process a flavor of PDF that is more suitable for archival preservation than traditional PDF. PDF/A-1 aims to preserve the static visual appearance of electronic documents over time and also aims to support future access and future migration needs by providing frameworks for: 1) embedding metadata about electronic documents, and 2) defining the logical structure and semantic properties of electronic documents. The result is a file format, based on PDF 1.4 that is more suitable for long term preservation.
PDF/A-1 files must include:

* Embedded fonts
* Device-independent color
* XMP metadata

The PDF Creator Pilot has property gets or sets the value indicating whether to produce a PDF/A compatible output file. There is ProducePDFA. Setting ProducePDFA to VARIANT_TRUE means that the output PDF file will be built compatible to the PDF/A standard. You should set this property before any text or graphics output.
If you need long-term preservation documents, use the PDF/A docs. With PDF Creator Pilot you can create such documents easy.

New PDF to Image Converter from Two Pilots Company

Thursday, March 11th, 2010

In the area of circulation of electronic documents, often we need to modify PDF documents into PNG or multipage TIFF images. Two Pilots, has just released a new converter called PDF2Image Pilot, a program for converting PDF files into high-quality BMP, EMF, GIF, JPEG, PNG, or TIFF images. (Multipage TIFF is supported as well.)

The PDF to Image converter is based on PDF Rasterization Pilot. PDF Rasterization Pilot is a library for developers. Using this tool, developers can add to their products such features as export PDF to graphic format and output PDF to a device context (display or printer).

The new PDF2Image Pilot uses only PDF Rasterization Pilot for saving PDF into graphic files and outputting PDF content to a preview window. In PDF2Image Pilot, we tried to connect the features of the PDF Rasterization library and our many years experience in the development of easy and useful interfaces. We hope that PDF2Image converter helps you to solve your tasks. We await your responses and proposals!
