Enlarge OLIVER legend swatches #226

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
The swatches in legends used in OLIVER can be a little too small to effectively 
see patterns.  This is the current URL to generate a legend:

http://giswebservices.massgis.state.ma.us/geoserver/wms?TRANSPARENT=TRUE&STYLE=G
ISDATA.SHELLFISHSUIT_POLY%3A%3ADefault&FOO=Shellfish%20Suitability%20Areas&VERSI
ON=1.1.1&SERVICE=WMS&REQUEST=GetLegendGraphic&EXCEPTIONS=application%2Fvnd.ogc.s
e_xml&LAYER=massgis%3AGISDATA.SHELLFISHSUIT_POLY&SCALE=2311168.08719717&FORMAT=i
mage%2Fgif

which results in an image this size: 144px × 200px  (W x H)

There is a way to add WIDTH and HEIGHT parameters to modify that size of the 
legend (as described in 
http://docs.geoserver.org/latest/en/user/services/wms/get_legend_graphic/legendg
raphic.html)

It may make sense to try it like this:

http://giswebservices.massgis.state.ma.us/geoserver/wms?TRANSPARENT=TRUE&STYLE=G
ISDATA.SHELLFISHSUIT_POLY%3A%3ADefault&FOO=Shellfish%20Suitability%20Areas&VERSI
ON=1.1.1&SERVICE=WMS&REQUEST=GetLegendGraphic&EXCEPTIONS=application%2Fvnd.ogc.s
e_xml&LAYER=massgis%3AGISDATA.SHELLFISHSUIT_POLY&SCALE=2311168.08719717&FORMAT=i
mage%2Fgif&HEIGHT=30&WIDTH=30

which results in an image this size: 154px × 300px (W x H)

which is only slightly wider than the original.  If the image is too wide for 
the right window width a horizontal scrollbar will appear which is good. 

I'm not sure if this is workable but it would be nice to experiment.

For now, hardcoded width and height to 30 and 20 in GeoExt.js
Would probably be better with variables but OK for now.
