Changeset 1082 in josm

Timestamp:

2008-11-18T08:40:49+01:00 (15 years ago)

Author:

Message:

• some changes regarding the "hatched download area": now also works for areas where server returns no data; colour preference is now called "outside downloaded area", not "downloaded Area"; changing the colour now invalidates the prepared pattern so that restart is not required; pattern is now transparent (patch from Stephan Knauss) so WMS and other layers are visible below. Fixes #1762, #1754, partly #1756
