I have created a small path for WMSLegend.js. Currently the FORMAT and
SCALE parameters are being added to the URL twice if they are specified as
parameters to the getLegendUrl function. This patch corrects the code so
that the default values are not appended if the parameters are already
present.
Do I need a Trac account to submit this patch? I have attached the diff
file below:
