Download Sumatra PDF 1.9

Sumatra PDF is a lightweight open source program for opening PDF documents. Installed, the program takes up 1.2MB, making it smaller than Foxit Reader. When a PDF document is printed, it is first converted internally to a bitmap image. This usually results in a large spooled file, which can cause quite a bit of delay on printers with low memory. Version 1.9 of Sumatra PDF was released on Wednesday and the changelog of this release looks like this:

Changes in this release:

• Support for CHM documents
• Support touch gestures, available on Windows 7 or later. Contributed by Robert Prouse
• Open linked audio and video files in an external media player
• Improved support for PDF transparency groups
