Questions and postings pertaining to the development of ImageMagick, feature enhancements, and ImageMagick internals. ImageMagick source code and algorithms are discussed here. Usage questions which are too arcane for the normal user list should also be posted here.
There's miter joins support for the draw operator but none that I can find for the stroke operator for text. There is no method for clean sharp edges for stroke paths. For example:
convert -size 256x256 xc:lime \
-draw 'gravity center font Impact-Regular font-size 200
stroke-width 50 stroke-linejoin miter
stroke black fill black text 0,0 "LY"
stroke transparent fill white text 0,0 "LY"' \
