The developer of Opacity, Like Thought, LLC, is now shipping version 1.1 of their app. Opacity 1.1 requires Mac OS X 10.5.2 and has a redesigned interface with a new grid and dynamically generated images in the toolbar. To make life easier for new users of Opacity, Like Thought also added a "How To" screencast and four new templates.
The biggest addition to Opacity 1.1 is support for SVG vector graphics for the Web. Opacity creates reusable workflows called factories, which now support such cool features as gamma stripping in PNG images, automatic uploading to Web sites using Cyberduck, and multi-page PDF images.
If you own Opacity 1.0, this is a free upgrade. A demo is available for download, and you can purchase Opacity for $89.
