PostScript (.ps)
Open BetaPostScript (.ps), Adobe की एक पृष्ठ-वर्णन भाषा है, जो PDF की पूर्ववर्ती है। वैज्ञानिक प्रकाशन के लिए एक प्री-प्रेस और अभिलेखीय मानक, हज़ारों प्रिंटरों और RIP सर्वरों में समर्थित। LaTeX पाइपलाइन (dvips → ps2pdf) के लिए और दीर्घकालिक अभिलेखागार में संपादन-योग्य वेक्टर मानचित्र लेआउट रखने के लिए आदर्श।

PostScript प्रारूप के बारे में
PostScript is a page description language invented by Adobe in the early 1980s; PDF grew directly out of it. A .ps file is, in essence, a small program executed by the interpreter inside a printer or a RIP server: it draws vector outlines, text and raster inserts. Level 3 is still understood by office and print-shop devices, and the free Ghostscript opens such a file on any operating system.
An OpenStreetMap map is exported to PostScript when the result goes into a printing or archival pipeline: hand it to a print shop, put it on a RIP, keep the layout in editable vector form for years ahead. For on-screen viewing the format is awkward — usually a .ps is first turned into a PDF with a single command.
Here is how the file is built on our side: QGIS draws the sheet in vector, the labels stay as text with embedded fonts, and then Ghostscript converts the result into PostScript Level 3 with a standard DSC structure. The sheet is 297x210 mm by default (A4 in landscape orientation), raster elements are 300 DPI. PostScript has no layers by the design of the format itself: the map arrives as a single stream of vector commands.

PostScript कैसे निर्यात करें
निर्यात के बाद कैसे खोलें
- Ghostscript (free) — both viewing and conversion: ps2pdf map.ps map.pdf gives you a PDF, and calling gs with -r300 rasterizes the sheet at the resolution you need.
- GSview on Windows or Evince on Linux — open the .ps directly and look at the page without converting it.
- Adobe Distiller — the regular prepress route: PostScript in, PDF with font and color control out.
- A print shop or a RIP server — the file is handed over as is; agree on the sheet size and margins in advance, otherwise the map will be trimmed at the edge.
- LaTeX — for pdflatex convert the file to PDF with ps2pdf and insert it with the usual includegraphics; in the classic latex + dvips pipeline EPS is more common for illustrations, and you can download that from us too.
