Interface STBIRInputCallback

All Superinterfaces:

Upcall

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface STBIRInputCallback
extends Upcall

typedef void const * (*STBIRInputCallback)(void* optional_output, void const * input_ptr, int num_pixels, int x, int y, void* context);
