fonts/type3_vectorlogo

 * Type 3 vector logo font:

 * Create a Type 3 font which contains a single logo derived from a vector

 * based PDF page

 *

 * Import vector data from a PDF file to create a Type 3 logo font containing

 * one glyph. Add the glyph to a custom encoding and output text with that

 * glyph.

 *

 * Required software: PDFlib+PDI/PPS 7

 * Required data: PDF file
