Interface STBIZlibCompressI

  • All Superinterfaces:
    org.lwjgl.system.CallbackI, org.lwjgl.system.Pointer
    All Known Implementing Classes:
    STBIZlibCompress
    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 STBIZlibCompressI
extends org.lwjgl.system.CallbackI
    Instances of this interface may be set to STBImageWrite.stbi_zlib_compress.

    Type

    
 unsigned char * (*invoke(long, int, long, int)) (
     unsigned char *data,
     int data_len,
     int *out_len,
     int quality
 )

      • getCallInterface

        default org.lwjgl.system.libffi.FFICIF getCallInterface()
        Specified by:
        getCallInterface in interface org.lwjgl.system.CallbackI

      • callback

        default void callback​(long ret,
                      long args)
        Specified by:
        callback in interface org.lwjgl.system.CallbackI

      • invoke

        long invoke​(long data,
            int data_len,
            long out_len,
            int quality)
        Compresses a block of data using Zlib compression.

        The returned data will be freed with MemoryUtil.memFree(java.nio.Buffer) so it must be heap allocated with MemoryUtil.memAlloc(int).

        Parameters:
        data - the data to compress
        data_len - the data length, in bytes
        out_len - returns the compressed data length, in bytes
        quality - the compression quality to use
        Returns:
        the compressed data
