Re: shader program in cairo graphics?

Hi, Jeong-joon

Doe that work for you?

cairo_set_source_rgba (cr, r, g, b, a);
/* fill a polygon */
cairo_move_to (cr, x, y);
cairo_line_to (cr, x1, y1);
......
cairo_close_path (cr);
cairo_fill (cr):

Henry

Subject: [cairo] shader program in cairo graphics?

Hi all,

I have a question whether there is, in cairo graphics, a function like a shader program shown in 3D graphics.

I hope to fill a polygon with some colors, and I hope to define the color as a function depending on the (x, y) position.

Is there any cairo API or data structure related with this functionality? or any examples? Any comment will be appreciated.

Thank you in advance.

Sincerely yours.
