PostScript Document Format (PS)

Show in webframe

PostScript (PostScript). PostScript is a simple interpretive page description language, also known as PDL, that is used to describe the appearance of text, graphical shapes and sampled images on printed or displayed pages. The page description and graphical capabilities of this language include arbitrary shapes, painting operators, fully integrated text and graphics, and sampled images derived from natural sources. Most advanced laser printers use PostScript in order to render electronic information on a printed page.

This filter can load files that are stored in memory (memory files). In addition, it supports an option that disables the cropping of files, by setting the PDF_DISABLE_CROPPING flag in the FILEPDFOPTIONS structure, and an option that disables the use of CIE colors, by setting the PDF_DISABLE_CIECOLORS flag in the FILEPDFOPTIONS structure. Disabling the use of CIE colors will result in faster loading of PS files.

Support for this format is available in the Barcode PDF modules and the PDF Plug in.

To determine whether this file format is unlocked, call L_SUPPORT_PDF_SAVE and L_SUPPORT_PDF_READ.
