Idea of Happy Filled Icon
There is a circle with medium bluntness of a line. There is a curved line in the bottom showing the mouth. There are two dots above the curved line showing the eyes. Both the line and dots are centered in the circle.
This is a Happy Filled icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,900 icons, all in the same style and quality.
