Work with PDF documents based on the PostScript data management and composition language by opening them in the suite with a command line interface providing options to view, render, edit, convert, resize and otherwise modify PDF content. Changelogs are kept.
GPL Ghostscript is a free source interpreter for the PostScript language and the Adobe Portable Document Format (PDF). It works along with different programs as a raster image processor for printers. It basically takes as input a set of graphics commands and interprets so that the output is a bitmap page when sent to an output device, such as a printer.
The program has a rudimentary interface that resembles Windows’ notepad. It only displays a command line where the users need to type the proper commands in order to view, render, convert, rasterize, resize and perform other tasks related to PDF documents.
Usually GPL Ghostscript is used by other applications as a general conversion and formatting engine and the user never interacts with it. The command line is only for advanced users who require interpreting PostScript, encapsulated PostScript, DOS EPS, or Adobe Portable Document Format. To use the command line consult the manuals and guidelines from the website. For a friendlier approach GPL Ghostscript integrates to GSview which is a graphical interface for Ghostscript that has to be downloaded additionally.
Basically GPL Ghostscript is used internally by PDF & Postcript conversion programs such as PDF printers, PDF to text or similar applications which need an interpreter of these mentioned data scripts in order to be converted or printed to different formats.
v9.09 [Sep 18, 2010]
This is the third release in the stable 9.x series.
This a an "out of order" release, primarily to ensure the GPL Ghostscript release remains in version "lock-step" with the Artifex commercial release.
Highlights in this release include:
For monochrome devices, there is a new halftone technique for sampled image data. The existing technique is very efficient (and is is still used) for large areas of color, such as an area fill, but encountered performance problems dealing with sampled image data where a given colour value only covered a few pixels at a time. The new approach applies the halftone threshold array directly to the image samples.
Further performance, memory use, and stability improvements with the new features introduced in 9.00, as well as Unix/Linux build fixes, plus the usual assorted bug fixes.
