Shortcut Software has announced the availability of Silkypix Developer Studio 4.0. While Silkypix is produced by a Japanese company called Ichikawa Soft Laboratory, the international distribution of the program has been managed for the past two years by Shortcut Software, which is headquartered in the US. Features new to version 4.0 include watermarking, editing of IPTC properties, history management, multi-CPU support, printer profiles and options, and more. Batch processing, shortcut keys and the cropping control panel have been improved. Silkypix Developer Studio 4.0 is available now for $149.
