PDF Generation

QPix provides the capability to create PDF files from a series of images or 4D pictures.

PDF supports several compression algorithms for embedded images (JPEG, ZIP, CCITT G4), each suited to different kinds of images. The following logic is used by QPix in order to decide which algorithm to use:

• If a source image is already compressed with JPEG, it is embedded as-is, i.e. without recompression.
• If the source image is not JPEG, QPix examines its pixel depth. If it is monochrome, it is compressed using CCITT G4 (the most efficient for b/w). If the image is not monochrome, it is compressed using ZIP.
