Hi all,
I have implemented a simple application to draw a set of 90 lines and
measure the execution time of drawing using Cairo.
In more detail, i want to draw a set of 90 linses, which constitute 388
points (average 4.3 points/line). I divide 90 lines into 3 groups and
draw each group in different colors/widths. It is noted that i draw each
line with border. The execution time is summarized as follows:
LINE_CAP_ROUND, LINE_JOIN_ROUND: it takes 802ms
LINE_CAP_BUTT, LINE_JOIN_MITTER: it takes 700ms
At the moment, i want to evaluate the performance of Cairo in terms of
speed for drawing and I need to achieve the time execution between 300ms
and 500ms (<300 is certainly wonderful). Is there any possible way for
speeding up my drawing with Cairo?
Thanks.
