Interface STBIZlibCompressI

  • All Superinterfaces:
    org.lwjgl.system.CallbackI, org.lwjgl.system.CallbackI.P, 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.P
    Instances of this interface may be set to STBImageWrite.stbi_zlib_compress.

    Type

      • getSignature

        default java.lang.String getSignature()
        Specified by:
        getSignature in interface org.lwjgl.system.CallbackI
      • callback

        default long callback​(long args)
        Specified by:
        callback in interface org.lwjgl.system.CallbackI.P
      • 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
