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

getOrderingConstraint

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

Specified by:
getOrderingConstraint in class PngChunk

getPosX

public long getPosX()

getPosY

public long getPosY()

getUnits

public int getUnits()
0: pixel, 1:micrometer


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

setPosX

public void setPosX(long posX)

setPosY

public void setPosY(long posY)

setUnits

public void setUnits(int units)
0: pixel, 1:micrometer
