I am a new user of GTK+ and of Cairo. That is why I would appreciate detailed answers for my questions. From the manual: "cairo_pattern_create_linear(x0,y0,x1,y1) - Before using the gradient pattern, a number of color stops should be defined using cairo_pattern_add_color_stop_rgb() or cairo_pattern_add_color_stop_rgba()." do i understand corerectly that this function is a general function - that is it says only to create a linear gradient between (x0,y0) and (x1,y1) points, and the colors are defined by, for example, cairo_pattern_add_color_stop_rgb() function ? cairo_pattern_add_color_stop_rgb (cairo_pattern_t *pattern, double offset, double red, double green, double blue) - whst does "offset" mean in terms of the colors? is it a number ? in which range it is varied ? Thank you. -- cairo mailing list [email protected] http://lists.cairographics.org/mailman/listinfo/cairo
