Sebastian Frysztak	3598cf19e8	Implement generic box blur	2017-02-15 11:22:06 +01:00
Sebastian Frysztak	72aec87047	Add SSSE3-based blur implementation. ... Calculations are done on integer, rather than floating point numbers, so this implementation is not as accurate (but when scale factor is reasonable enough, no artifacs are visible). It is, however, faster by a factor of ~3.	2016-10-29 14:32:49 +02:00
Sebastian Frysztak	afe41c5754	Extend kernel size to 15x15.	2016-10-28 17:35:33 +02:00
Sebastian Frysztak	fb5dbbe661	Add SSE2-optimized blur. ... About 4-6 times faster than naive implementation.	2016-10-22 15:30:27 +02:00
Sebastian Frysztak	ade9a20788	Isolate blur implementation to a function. ... This will allow easier switching between naive/SSE2/AVX implementations.	2016-10-22 14:32:35 +02:00
Chris Guillott	c3a95b86d6	add initial blur support ... thanks to https://github.com/shiver/i3lock	2016-10-14 22:06:43 -04:00
