public void cloneDataFromRead(final PngChunk other)

Implements abstract jogamp.opengl.util.pngj.chunks.PngChunk.cloneDataFromRead.

Doc from jogamp.opengl.util.pngj.chunks.PngChunk.cloneDataFromRead.

Makes a copy of the chunk.

This is used when copying chunks from a reader to a writer

It should normally be a deep copy, and after the cloning this.equals(other) should return true

public ChunkRaw createRawChunk()

Implements abstract jogamp.opengl.util.pngj.chunks.PngChunk.createRawChunk.

Doc from jogamp.opengl.util.pngj.chunks.PngChunk.createRawChunk.

Creates the physical chunk. This is used when writing (serialization). Each particular chunk class implements its own logic.

Returns:ChunkRaw

A newly allocated and filled raw chunk
