[cairo] Reg : Cairo_mask

[swati upadhyaya]

Hi all,
           I want to use different kinds for brush for line drawing using
cairo. Is there any way to do so. Like if I will set the alpha < 1 in
stop_rbga API in any pattern the its look like water color effects. Is
there any way to set the hardness or softness of brush, opaqueness etc ect
for brush.
Some one told me to use cairo_mask but i am not sure how to use this.. If
possible let me know sample code..


Kindly reply
Swati
