Method Summary

Modifier and Type	Method	Description
void	run(DrawFuncs dfuncs, @Nullable MemorySegment drawData, DrawState st, float control1X, float control1Y, float control2X, float control2Y, float toX, float toY)	A virtual method for the hb_draw_funcs_t to perform a "cubic-to" draw operation.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(MemorySegment, MemorySegment, MemorySegment, float, float, float, float, float, float, MemorySegment) method.
default void	upcall(MemorySegment dfuncs, MemorySegment drawData, MemorySegment st, float control1X, float control1Y, float control2X, float control2Y, float toX, float toY, MemorySegment userData)	The upcall method is called from native code.

Method Details

run

void run(DrawFuncs dfuncs,
 @Nullable MemorySegment drawData,
 DrawState st,
 float control1X,
 float control1Y,
 float control2X,
 float control2Y,
 float toX,
 float toY)

A virtual method for the hb_draw_funcs_t to perform a "cubic-to" draw operation.

Parameters:

dfuncs - draw functions object

drawData - The data accompanying the draw functions in hb_font_draw_glyph()

st - current draw state

control1X - X component of first control point

control1Y - Y component of first control point

control2X - X component of second control point

control2Y - Y component of second control point

toX - X component of target point

toY - Y component of target point

Since:

4.0.0

upcall

default void upcall(MemorySegment dfuncs,
 MemorySegment drawData,
 MemorySegment st,
 float control1X,
 float control1Y,
 float control2X,
 float control2Y,
 float toX,
 float toY,
 MemorySegment userData)

The upcall method is called from native code. The parameters are marshaled and run(DrawFuncs, MemorySegment, DrawState, float, float, float, float, float, float) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

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

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
