Map Printing

We want to be able to Print maps.

This will require access to the same view as the user is seeing, so will require using their Authentication & saving all their settings (Viewport/Active Layers/Filter Status) & passing to a Browser.

e.g.

• ​http://phantomjs.org (WebKit-based)
• ​http://www.slimerjs.org (Gecko-based)

We have a solution in trunk based on using PhantomJS via Selenium:

• UserGuidelines/Admin/MapPrinting

Older thoughts:

• PakistanDevelopers#Printing

Another option is using Java:

• ​MapFish Printing Module
  • InstallationGuidelines
  • Reasons why Java was chosen: ​http://trac.mapfish.org/trac/mapfish/wiki/Proposals/PrintModuleSpec
  • GeoExplorer notes on this: ​http://projects.opengeo.org/geoext/wiki/Printing
• We'd like to be able to print to an Image not just a PDF:
  • ​http://trac.mapfish.org/trac/mapfish/ticket/161

Alternate Java:

• ​Geomajas

Python:

• ​http://trac.osgeo.org/openlayers/wiki/TileStitchingPrinting
• Possibly-useful libraries:
  • ​ReportLab
    • ​rST2PDF
  • ​XHTML2PDF (Pisa)
  • ​PyPDF

A JavaScript library:

• ​JSPDF

Other:

• ​http://www.htmldoc.org - used by ​http://trac-hacks.org/wiki/TracWikiToPdfPlugin
• ​https://medium.com/nyc-planning-digital/printing-web-maps-83e7d9d3d467

PDF export of data attributes is a representation added to the RESTlike controller.

Printing the current view would be the same as printing a WebMapContext.
