Method Summary

Modifier and Type	Method	Description
boolean	run(@Nullable MemorySegment f, Pixbuf pixbuf, @Nullable String @Nullable [] paramKeys, @Nullable String @Nullable [] paramValues)	Saves a GdkPixbuf into a standard C file stream.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(MemorySegment, MemorySegment, MemorySegment, MemorySegment, MemorySegment) method.
default int	upcall(MemorySegment f, MemorySegment pixbuf, MemorySegment paramKeys, MemorySegment paramValues, MemorySegment _gerrorPointer)	The upcall method is called from native code.

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.

Parameters:

f - the file stream into which the image should be saved

pixbuf - the image to save

paramKeys - parameter keys to save

paramValues - parameter values to save

Returns:

TRUE on success; in case of failure, FALSE is returned and the error is set

Throws:

GErrorException - see GError

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(MemorySegment, Pixbuf, String[], String[]) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

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

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
