PngChunkIHDR

public PngChunkIHDR(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

getBitspc

public int getBitspc()

getColormodel

public int getColormodel()

getCols

public int getCols()

getCompmeth

public int getCompmeth()

getFilmeth

public int getFilmeth()

getInterlaced

public int getInterlaced()

getOrderingConstraint

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

Specified by:
getOrderingConstraint in class PngChunk

getRows

public int getRows()

parseFromRaw

public void parseFromRaw(ChunkRaw c)
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

setBitspc

public void setBitspc(int bitspc)

setColormodel

public void setColormodel(int colormodel)

setCols

public void setCols(int cols)

setFilmeth

public void setFilmeth(int filmeth)

setInterlaced

public void setInterlaced(int interlaced)

setRows

public void setRows(int rows)
