Subject: Fix for "fill logic signal high areas" feature
X-Git-Url: https://sigrok.org/gitweb/?p=pulseview.git;a=commitdiff_plain;h=bae42c1d8a6fbe65e412d56edecdd4b354908339

Fix for "fill logic signal high areas" feature

At certain zoom levels, the algorithm wrongly fills areas where
the signal is low. This patch fixes this.
