cairo_pattern_get_linear_points — cairo_pattern_get_linear_points • cairocore

Gets the gradient endpoints for a linear gradient.

cairo_pattern_get_linear_points(pattern, x0, y0, x1, y1)

Arguments

pattern	[`cairo_pattern_t *`] a #cairo_pattern_t
x0	[`double *`] return value for the x coordinate of the first point, or %NULL
y0	[`double *`] return value for the y coordinate of the first point, or %NULL
x1	[`double *`] return value for the x coordinate of the second point, or %NULL
y1	[`double *`] return value for the y coordinate of the second point, or %NULL

Value

[int]

Details

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

Since: 1.4
