PostScript (.ps)
Open BetaPostScript（.ps）是 Adobe 开发的页面描述语言，是 PDF 的前身。它是印前及科技出版归档领域的标准，数千种打印机和 RIP 服务器均支持。非常适合 LaTeX 流水线（dvips → ps2pdf），也适合在长期归档中保存可编辑的矢量地图版面。

关于 PostScript 格式
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.

谁在使用 PostScript 地图
如何导出 PostScript
导出后如何打开
- 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.
