Snap & Split

March 11th, 2009 · 5 Comments

We’ve been advancing the editing capabilities of OpenLayers with each release since the initial inclusion of the vector feature rendering in 2.4.  The upcoming 2.8 release will bring two new enhancements that I’m particularly excited about: snapping and splitting. The snapping example demonstrates some of the configuration options of the snapping agent.  This control can […]

Cluster Strategy

June 23rd, 2008 · 5 Comments

Following up on the paging strategy, I’ve put together a cluster strategy as an alternative for managing large numbers of (potentially coincident) features. The cluster strategy intercepts batches of features before they are added to a layer. It caches all features, creates points that represent clusters of features, and sends the clusters to the layer […]

April 22nd, 2007 · Comments Off

OpenLayers supports something called Build Profiles. These allow you to build a single file OpenLayers.js which contains all the code you need and only the code you need. In order to target a minimal changeset for OpenLayers 2.4, we’ve added an additional profile, ‘full’, which contains the OpenLayers Vector changes. These changes increase the library […]

Vector Drawing Icons

March 27th, 2007 · 1 Comment

Recently, a mailing list post on the Dev list asked where we had gotten the awesome Vector Drawing icons from. I’d like to publicly thank CitySafe, and specifically, Ed Dowding, for uploading the icons to the Vector Drawing wiki page many moons ago, and granting their use to the OpenLayers project.
