Method Details

run

boolean run(@Nullable MemorySegment f,
 Pixbuf pixbuf,
 @Nullable String @Nullable [] paramKeys,
 @Nullable String @Nullable [] paramValues)
     throws GErrorException

Saves a GdkPixbuf into a standard C file stream.

The optional param_keys and param_values arrays contain the keys and values (in the same order) for attributes to be saved alongside the image data.

Throws:

GErrorException

upcall

default int upcall(MemorySegment f,
 MemorySegment pixbuf,
 MemorySegment paramKeys,
 MemorySegment paramValues,
 MemorySegment _gerrorPointer)

The upcall method is called from native code. The parameters are marshaled and run(java.lang.foreign.MemorySegment, org.gnome.gdkpixbuf.Pixbuf, java.lang.String[], java.lang.String[]) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment) method.

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated
