Make Icon

n Mac OS X, the application can read PDF files and uses the first page to create the icon. On non PDF files, it tries to open the file as a picture using QuickTime and takes the main image inside the file. So it should work with all file types QuickTime can read. e.g. TIFF, JPEG, BMP, Photoshop, GIF, PNG, etc.
The Realbasic source code is included. This application shows REALbasic developers how to use the PDF and Icon classes to generate icons based on a given picture and how to make a picture from a page in a PDF file.

Requirements:

Mac OS 8 or newer
Mac OS X for PDF functions
