Method Summary

Modifier and Type	Method	Description
void	run(PaintFuncs funcs, @Nullable MemorySegment paintData, Bool isForeground, Color color)	A virtual method for the hb_paint_funcs_t to paint a color everywhere within the current clip.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(MemorySegment, MemorySegment, int, int, MemorySegment) method.
default void	upcall(MemorySegment funcs, MemorySegment paintData, int isForeground, int color, MemorySegment userData)	The upcall method is called from native code.

Method Details

run

void run(PaintFuncs funcs,
 @Nullable MemorySegment paintData,
 Bool isForeground,
 Color color)

A virtual method for the hb_paint_funcs_t to paint a color everywhere within the current clip.

Parameters:

funcs - paint functions object

paintData - The data accompanying the paint functions in hb_font_paint_glyph()

isForeground - whether the color is the foreground

color - The color to use, unpremultiplied

Since:

7.0.0

upcall

default void upcall(MemorySegment funcs,
 MemorySegment paintData,
 int isForeground,
 int color,
 MemorySegment userData)

The upcall method is called from native code. The parameters are marshaled and run(PaintFuncs, MemorySegment, Bool, Color) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

Creates a native function pointer to the upcall(MemorySegment, MemorySegment, int, int, MemorySegment) method.

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
