How to install vista fonts on CentOS

Microsoft’s new ClearType fonts for Vista are great. The fonts include Constantia, Corbel, Calibri, Cambria, Candara and Consolas.


To install the Vista ClearType fonts in CentOS, you need to install cabextract first. You can use yum to install it:

$ yum install Cabextract

Then, use following script to install the Vista fonts:

Then open up a text editor and copy and paste the script into that file.
Then run the script using:

$ sh vista-fonts-installer.sh

The script downloads the Powerpoint Viewer
installer from microsoft.com, and then extracts the Vista cleartype
fonts using cabextract. These fonts are then installed in the ~/.fonts
directory.

Please remember that the ClearType Vista fonts are not free. You’ll be installing them at your own risk!
