New version preserves transparency on TIFF, PNG
Zevrix has launched PDF Checkpoint 1.2, updating its PDF preflight and conversion software. The app exports PDFs as images, and splits and reduces the size of PDF files. Hundreds of files can be handled at a time via drag-and-drop batch processing.
Version 1.2 adds the ability to preserve transparency when exporting PDFs to either TIFF or PNG format. The updated Checkpoint requires Mac OS X 10.4.2, and is Snow Leopard-compatible. It costs $70 and arrives bundled with Graphic Inspector.
