PostScript Document Format (PS)

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 PDFDisableCropping property (ILEADRasterIO), and an option that disables the use of CIE colors, by setting the PDFDisableCieColors property (ILEADRasterIO). 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. For more information on the available products, refer to Topic Selection. Support for this file format can be unlocked using one of the following support constants: L_KEY_PDF, L_KEY_PDF_SAVE, L_KEY_OCR_PDF_OUTPUT, L_KEY_BARCODES_PDF_READ, or L_KEY_BARCODES_PDF_WRITE.
