Constructor Details

LinearGradient

public LinearGradient(MemorySegment address)

Constructor used internally to instantiate a java LinearPattern 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 LinearGradient create(double x0,
 double y0,
 double x1,
 double y1)

Create a new linear gradient Pattern along the line defined by (x0, y0) and (x1, y1). Before using the gradient pattern, a number of color stops should be defined using Gradient.addColorStopRGB(double, double, double, double) or Gradient.addColorStopRGBA(double, double, double, double, double).

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:

x0 - x coordinate of the start point

y0 - y coordinate of the start point

x1 - x coordinate of the end point

y1 - y coordinate of the end point

Returns:

the newly created Pattern

Since:

1.0

getLinearPoints

public Point[] getLinearPoints()

Gets the gradient endpoints for a linear gradient.

Returns:

a 2-element Point array with the x and y coordinates of the first and second point

Since:
