Changeset 2778 for libpipiTweet

Timestamp:

Aug 27, 2008, 1:28:48 PM (13 years ago)

Author:

Jean-Yves Lamoureux

Message:

• Moved *line_template.c to .h files to avoid problems with autotools (sam)
• Added antialiasing support to polylines
• Ho, and previous commit (r2777) contains width/height/pitch accessors to pipi_image_t, too. LOL.

Location:

libpipi/trunk/pipi

Files:

• paint/aline_template.h (moved) (moved from libpipi/trunk/pipi/paint/aline_template.c)
• paint/line.c (modified) (8 diffs)
• paint/line_template.h (moved) (moved from libpipi/trunk/pipi/paint/line_template.c)
• pipi.h (modified) (1 diff)
