Méthode Description
Close ( ) : void

does NOT close the associated stream!
Flush ( ) : void
ForceChunkEnd ( ) : void

sometimes last row read does not fully consumes the chunk here we read the reamaing dummy bytes
GetIdLastChunk ( ) : byte[]
GetLenLastChunk ( ) : int
GetOffset ( ) : long
IsEnded ( ) : bool
PngIDatChunkInputStream ( Stream iStream, int lenFirstChunk, long offset_0 ) : System

Constructor must be called just after reading length and id of first IDAT chunk
Read ( byte b ) : int
Read ( byte b, int off, int len_0 ) : int

This can return less than len, but never 0 Returns -1 nothing more to read, -2 if "pseudo file" ended prematurely. That is our error.
ReadByte ( ) : int
Seek ( long offset, SeekOrigin origin ) : long
SetLength ( long value ) : void
Write ( byte buffer, int offset, int count ) : void

Private Methods

Méthode Description
DisableCrcCheck ( ) : void

Disables CRC checking. This can make reading faster
EndChunkGoForNext ( ) : void
