The BorderFX plug-in for Aperture has been completely rebuilt as a standalone application, and will include a Photos Extension. It is still a few weeks away from being released, but I will post some screenshots and a video preview soon.
This update corrects an issue that could cause the Watermarks to render incorrectly on exported images. Fixed a problem that caused BorderFX to not launch on Mac OS X Lion (10.7.5).
Please note that an earlier version of 1.8.3 (404), released a few days ago does not include the fix that allows BorderFX to run on 10.7, you will need to download and install BorderFX 1.8.3 (405).
A new version of Aperture BorderFX has been released, this update includes support to create Collages in the BorderFX Edit plug-in. Other improvements include the ability to rotate text, including text watermarks. I will try to add support to rotate image watermarks in the next minor release.
