Constructor Details

ScaleOpBitmapImpl

public ScaleOpBitmapImpl(ImageOp sop,
 double scale)

Constructs an ImageOp which will scale the image produced by its source ImageOp.

Parameters:

sop - the source operation

scale - the scale factor

ScaleOpBitmapImpl

public ScaleOpBitmapImpl(ImageOp sop,
 double scale,
 RenderingHints hints)

Constructs an ImageOp which will scale the image produced by its source ImageOp.

Parameters:

sop - the source operation

scale - the scale factor

hints - rendering hints

Method Details

getSources

public List<Op<?>> getSources()

Description copied from class: AbstractOpImpl

Returns a list of Ops on which this Op depends.

Specified by:
