Font Dilation (font outline) #640

Open rgb2hsv opened 1 year ago

rgb2hsv commented 1 year ago

This PR adds font dilation as nvgFontDilate() to give better emphasis to text, especially when it is overlaid on an unknown background color or image. It is implemented with gray level morphology, which is approximated with directional convolutions. It can also be used in combination with nvgFontBlur() for a smoother fall-off. dump
