Review request for Calligra. Repository: calligra Description ------- This patch intends to fix the broken speed sensor of the brush tool. It's based on a patch I got from Wolthera, which was discarded/unfinished because the output of the sensor remained "blobby". I added a smoothing formula to the speed output : output_speed = current_speed * 0.1 + last_speed * 0.9 The used numeric values are either eyeballed or wild guessed from usage. There's certainly room for improvements on this patch. Diffs ----- krita/image/brushengine/kis_paint_information.cc 264ad43 krita/image/kis_distance_information.h 70fa25e krita/image/kis_distance_information.cpp 1c1c847 krita/plugins/paintops/libpaintop/sensors/kis_dynamic_sensors.cc 6b10e2b Diff: https://git.reviewboard.kde.org/r/120875/diff/ Testing ------- I tested the ux of a speed bound preset before and after the patch and compared to the behaviour of a similar test brush in Mypaint. Results are noticeable improvements when painting strokes at different speeds with the fix. It's also been tested by Wolthera Thanks, Damien de Lemeny
