Description Martin Horák 2008-08-01 15:11:10 UTC

Hello,

I am working on a project which uses the cairo library for primary graphics rendering. Because I quickly needed a special (not currently available in the version 1.6.4) join and end caps for lines, I implemented them myself. I added new two options to type cairo_line_join_t (CAIRO_LINE_JOIN_TRIANGLE, CAIRO_LINE_JOIN_NONE) and one option to type cairo_line_cap_t(CAIRO_LINE_CAP_TRIANGLE) The patches for cairo.h and cairo-path-stroke.c files are attached. I hope they will be useful.

Regards,
Martin Horak

Screenshots?  I can't guess what the new caps and join look like.

A triangle cap is shown in page 213 (fig. 22-11 (3)) and triangle join is in 
page 214 (fig. 22-12 (3)) of the PCL reference available at
