metaobject releases version 1.1 of BookLightning, the lightweight imposition program for booklets and simple magazines
Version 1.1 uses our newest EGOS engine to dramatically improve performance to the point where conversion is instantaneous for most files. Furthermore, the switch to EGOS for PDF generation removes some Quartz incompatibilities that had cropped up in Panther. BookLightning still allows you to easily create booklets for stapling or folding from any PDF file.
