PngChunkPLTE

public PngChunkPLTE(ImageInfo info)
Method Detail

cloneDataFromRead

public void cloneDataFromRead(PngChunk other)
Description copied from class: PngChunk
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

Specified by:
cloneDataFromRead in class PngChunk

createRawChunk

public ChunkRaw createRawChunk()
Description copied from class: PngChunk
Creates the physical chunk. This is used when writing (serialization). Each particular chunk class implements its own logic.

Specified by:
createRawChunk in class PngChunk
Returns:
A newly allocated and filled raw chunk

getEntry

public int getEntry(int n)

getEntryRgb

public void getEntryRgb(int n,
                        int[] rgb)

getEntryRgb

public void getEntryRgb(int n,
                        int[] rgb,
                        int offset)

getNentries

public int getNentries()

getOrderingConstraint

public PngChunk.ChunkOrderingConstraint getOrderingConstraint()
Description copied from class: PngChunk
see PngChunk.ChunkOrderingConstraint

Specified by:
getOrderingConstraint in class PngChunk

minBitDepth

public int minBitDepth()

parseFromRaw

public void parseFromRaw(ChunkRaw chunk)
Description copied from class: PngChunk
Parses raw chunk and fill inside data. This is used when reading (deserialization). Each particular chunk class implements its own logic.

Specified by:
parseFromRaw in class PngChunk

setEntry

public void setEntry(int n,
                     int r,
                     int g,
                     int b)

setNentries

public void setNentries(int n)
