Registers this
chunk class with TPNGObject.
type TChunkClass = class of TChunk;
procedure RegisterChunk(ChunkClass: TChunkClass);
Description
Use RegisterChunk method to register a new class using
TChunk as it's ancestor. The method will use the
last four letters from the chunk name as the chunk name (Or you may also
set fName variable on the constructor). When the component reads a chunk
using the same name as a registered chunk it will use
LoadFromStream method to load the
data and SaveToStream when saving.
If you
intend to create new chunk classes you must call this method before
loading or saving image using TPngObject. See
example 2 to see an example registering a new
chunk class.
