Constructor Details

RadialGradient

public RadialGradient(MemorySegment address)

Constructor used internally to instantiate a java RadialPattern object for a native cairo_pattern_t instance

Parameters:

address - the memory address of the native cairo_pattern_t instance

Method Details

create

public static RadialGradient create(double cx0,
 double cy0,
 double radius0,
 double cx1,
 double cy1,
 double radius1)

Creates a new radial gradient cairo_pattern_t between the two circles defined by (cx0, cy0, radius0) and (cx1, cy1, radius1). 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().

Note: The coordinates here are in pattern space. For a new pattern, pattern space is identical to user space, but the relationship between the spaces can be changed with cairo_pattern_set_matrix().

Parameters:

cx0 - x coordinate for the center of the start circle

cy0 - y coordinate for the center of the start circle

radius0 - radius of the start circle

cx1 - x coordinate for the center of the end circle

cy1 - y coordinate for the center of the end circle

radius1 - radius of the end circle

Returns:

the newly created RadialGradient

Since:

1.0

getRadialCircles

public Circle[] getRadialCircles()

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

Returns:

a 2-element Circle array with the x and y coordinates and radius of the first and second circle

Since:
