We now reuse tile images by maintaining a cache of image elements with a
simplified LRU expiry policy (by order, not by timestamp). The tile queue
is bypassed for images that are available in the cache, so they can be
rendered immediately. And the tile queue itself loads more than just one
image at a time now (2 per layer url).
Previously, minFrameRate could not be set as option with the start method.
The tests failed to catch this flaw. Now both the start method and the
tests are fixed.
OpenLayers.INCHES_PER_UNIT.m should equal
OpenLayers.INCHES_PER_UNIT.Meters, just like OpenLayers.INCHES_PER_UNIT.km
should equal OpenLayers.Inches_PER_UNIT.Kilometers. This confusion probably
comes from mixing International inches with US Survey inches when compiling
the unit conversion list (1 meter is 39.37007874 International inches, but
39.37 US Survey inches. It may not be obvious, but 'inches'/'Inch' in
OpenLayers means US Survey inch, and 'IInch' means International inch).
This change also fixes offsets caused by incorrect resolution calculations in
OpenLayers.Format.WMTSCapabilities.
The new minFrameRate option is used to make sure that an animation does not
run longer than the time calculated from that frame rate. Time is made up
by skipping frames, i.e. skipping execution of the eachStep callback.
This avoids issues with Elements renderers, where the nodeFactory method
cannot find nodes while the map viewport is transitioning from the mapDiv
to the googleControl.
Simple and effective: As soon as a map has a Google layer, the whole map viewport is added as control to the GMap. As soon as no Google layer is visible on the map any more, the map viewport is appended to the map container again. With this change, OpenLayers strictly limits its GMaps integration to the GMaps API.
Also note that there are no css overrides for the attribution any more. Instead, controls can now be conditionally positioned differently for Google layer by using the .olForeignContainer selector.
When a vector layer is exported to an OWSContext document, we throw an
exception when the layer contains no features, and the geometries are to be
exported inside of an InlineGeometry-element.
This commit fixes this behaviour by exporting sth. like this in such cases:
<Layer name="vector" hidden="0">i
<ows:Title xmlns:ows="http://www.opengis.net/ows"/>
<InlineGeometry/>
</Layer>
minScale and maxScale values of 0 and Infinity do not make sense in
OpenLayers, but they are used in WMS GetCapabilities 1.1.1 to indicate
that there is no minScale or maxScale restriction. Assuming that the
capability values for minScale and maxScale are passed as config options
to a WMS layer, it is better to not set minScale and maxScale when 0 or
Infinity are found in the ScaleHint.
