Dear list, with help from Michael I extended the ellipse area to a superellipse.
The user parameter 'r' has changed to become a float value. Values 0 < r < 1 the area looks like a four edge star. Value r = 1 the area get a rhombus. Values 1 < r < 2 the area is a rhombus with concave sides. Value r = 2 the area is an ellipse or a circle. Values 2 < r the area looks like a rectangular with round edges. Value = 0 (default, unset) the area is rectangular. Because of the usage of math functions I added more code testing the return values. The parameter r=2 to get an ellipse delogo area seems non intuitive to me. We should add a better description for the users of the delogo filter. The patch has been tested with 'make fate-rsync fate' rebased on the master branch commit 268d0b6527cba1ebac1f44347578617341f85c35 and applies clean to my previous patchset "Patch to create a circular delogo area" Please have a look. best regards Jörg Jörg Habenicht (2): avfilter/delogo: changed type of parameter 'r' to float avfilter/delogo: change delogo round area to superellipse area libavfilter/vf_delogo.c | 72 +++++++++++++++++++++++++++++++++-------- 1 file changed, 58 insertions(+), 14 deletions(-) -- 2.45.3 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
