PNGData(int type, byte[] data, int crc)- Constructor for reading a generic chunk.
|
boolean | chunkFull()- Returns true if the chunk is filled.
|
void | deflateToChunk(Deflater def)- Deflates the available data in def to the chunk.
|
void | feedToInflater(Inflater inf)- Feeds the data in the chunk to a ZIP inflater object.

PNGData
protected PNGData(int chunkSize)
Constructor for creating new chunks.
(only used by subclasses - creating a generic chunk is rather useless)
PNGData
protected PNGData(int type,
byte[] data,
int crc) Constructor for reading a generic chunk.
chunkFull
public boolean chunkFull()
Returns true if the chunk is filled.
shrink
public void shrink()
Shrink the chunk to offset size, used for the last chunk in a stream
(no trailing data!)
toString
public String toString()
Convert this Object to a human-readable String.
There are no limits placed on how long this String
should be or what it should contain. We suggest you
make it as intuitive as possible to be able to place
it into
System.out.println()
and such.
It is typical, but not required, to ensure that this method
never completes abruptly with a
RuntimeException.
This method will be called when performing string
concatenation with this object. If the result is
null, string concatenation will instead
use
"null".
The default implementation returns
getClass().getName() + "@" +
Integer.toHexString(hashCode()).
- toString in interface PNGChunk
- the String representing this Object, which may be null
