Back to [[wxGUI]]
The '''Cartographic Composer''' (so called ''wx.psmap'') is a GUI application which allows GRASS users to prepare interactively hardcopy map outputs. The application can write a instructions file for GRASS module {{cmd|ps.map}}, and then run this module on the background to create PostScript output directly. See the [http://lists.osgeo.org/pipermail/grass-user/2011-March/060158.html announcement] in the mailing list. See also the {{cmd|wxGUI.psmap|desc=manual}}.


{{cmd|ps.map}} (see also {{AddonCmd|ps.output}}) is a ''cartographic composer'', intended to be a stand-alone hardcopy plot generator. It is not meant to be a '''Print''' button for the maps currently displayed in the map canvas, that will need it own controls.
Cartographic Composer is release under [https://svn.osgeo.org/grass/grass/trunk/GPL.TXT GNU GPL] licence and the source is available from [https://svn.osgeo.org/grass/grass/trunk/gui/wxpython/psmap GRASS SVN repository]. The composer is part of core GRASS GIS. To run the composer, it is necessary to have the [http://pythonware.com/products/pil Python Imaging Library] (on some systems called "python-pillow" package) installed.


The GUI will prepare a semi-WYSIWYG + tree menu controls which can write a {{cmd|ps.map}} control file, and then run {{cmd|ps.map}} to create PostScript PDF output directly. Loading a {{cmd|ps.map}} control file is harder and can happen later.

=== Requirements ===
 
* '''GRASS 6.4.2+''' is required. On MS Windows you can try [http://wingrass.fsv.cvut.cz daily builds] which already comes {{addonCmd|wx.psmap}} installed.
* ''(optional)'' [http://www.pythonware.com/products/pil/ Python Imaging Library] for preview functionality
* ''(optional)'' [http://www.ps2pdf.com ps2pdf] for PDF export

For development issues see Trac page.

The Cartographic Composer (so called wx.psmap) is a GUI application which allows GRASS users to prepare interactively hardcopy map outputs. The application can write a instructions file for GRASS module ps.map, and then run this module on the background to create PostScript output directly. See the announcement in the mailing list. See also the manual.

Cartographic Composer is release under GNU GPL licence and the source is available from GRASS SVN repository. The composer is part of core GRASS GIS. To run the composer, it is necessary to have the Python Imaging Library (on some systems called "python-pillow" package) installed.

Note: ps.map (see also ps.output) is a GRASS module, intended to be a stand-alone hardcopy plot generator. It is not meant to be a Print button for the maps currently displayed in the map canvas, that will need it own controls.

The Cartographic Composer is available in GRASS 6.4.2+ from the Layer manager menu File → Cartographic Composer or from the toolbar .

In GRASS 7 the tool is also available from the command line as stand-alone application (g.gui.psmap).
