cairo_pattern_get_radial_circles: cairo_pattern_get_radial_circles

In coolbutuseless/cairocore: Low-Level Cairo Bindings

Description

Gets the gradient endpoint circles for a radial gradient, each specified as a center coordinate and a radius.

Usage

cairo_pattern_get_radial_circles(pattern, x0, y0, r0, x1, y1, r1)

Arguments

pattern	[cairo_pattern_t *] a #cairo_pattern_t
x0	[double *] return value for the x coordinate of the center of the first circle, or %NULL
y0	[double *] return value for the y coordinate of the center of the first circle, or %NULL
r0	[double *] return value for the radius of the first circle, or %NULL
x1	[double *] return value for the x coordinate of the center of the second circle, or %NULL
y1	[double *] return value for the y coordinate of the center of the second circle, or %NULL
r1	[double *] return value for the radius of the second circle, or %NULL

Details

Return value: %CAIRO_STATUS_SUCCESS, or %CAIRO_STATUS_PATTERN_TYPE_MISMATCH if pattern is not a radial gradient pattern.

Since: 1.4
