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
 )

      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
