Xpdf 4.00 released, with free PDF viewer for Windows & Linux
Glyph & Cog is pleased to announce version 4.00 of Xpdf and all of the Xpdf libraries and components.
For commercial licensees, there won't be any major changes. We do periodic, incremental releases, so 4.00 isn't a big step from 3.04.32.
The open source Xpdf viewer has moved to the Qt toolkit, based on our XpdfWidget library. We now have a free PDF viewer for Windows and Linux, which you can download from:
This free binary download version includes some features not available in the open source: color management, the DeviceN rasterizer, and overprint preview.
XpdfWidget with Qt Quick support
The latest version of XpdfWidget has initial support for Qt Quick and QML. The support isn't quite complete yet, and we'd love to have more customers testing it. If you're already an XpdfWidget licensee, the Qt Quick code is included in your license. If you're not a current license and you'd like to arrange an evaluation, please contact us at email@example.com.
The PDF 2.0 spec (ISO 32000-2) is moving toward completion. We've been following the work being done by the committee, and Xpdf already includes code to support most of the important PDF 2.0 changes.
Linear text selection
Xpdf, XpdfViewer, and XpdfWidget now support linear text selection. Older versions only offered one option: rectangular selection. Version 4.00 adds support for linear text selection, i.e., traditional mouse selection that follows lines and columns of text. To enable it:
in Xpdf (our free PDF viewer) -- there is a clickable icon in the toolbar to toggle between rectangular and linear selection
in XpdfViewer -- use the setLinearSelectMode function (for the ActiveX control), or the pdfSetLinearSelectMode function (for the DLL):
in XpdfWidget -- use the setLinearSelectMode function:
We've done a bunch of work recently on Xpdf's color management code. If you have an XpdfRasterizer license, there's information on configuring color management on our web site:
If you just want to take a quick look, color management and overprint preview are also available in our free viewer:
The XpdfRMW source toolkit now includes linearization capability. Linearization, aka "web optimization", is the process of rearranging the objects in a PDF file to make it possible to access incrementally over a network. Or, to put it simply, linearized PDF files on the web open faster in Acrobat.
XpdfRMW is our PDF "read-modify-write" library. It's distributed as an add-on to the Xpdf source package.
