FixedScaleOpBitmapImpl

public FixedScaleOpBitmapImpl(ImageOp sop,
 double scale,
 int width,
 int height)

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

Parameters:

sop - the source operation

scale - the scale factor

FixedScaleOpBitmapImpl

public FixedScaleOpBitmapImpl(ImageOp sop,
 double scale,
 int width,
 int height,
 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

fixSize

protected void fixSize()
