All Implemented Interfaces:

public class RotateScaleOpBitmapImpl
extends AbstractTileOpImpl
implements RotateScaleOp

An ImageOp which rotates and scales its source. Rotation is about the center of the source image, and scaling ranges from (0,Double.MAX_VALUE). If a source is to be both rotated and scaled, using one RotateScaleOp will produce better results than doing the rotation and scaling separately with one RotateOp and one ScaleOp.

Since:

3.1.0

Constructor Details

RotateScaleOpBitmapImpl

public RotateScaleOpBitmapImpl(ImageOp sop,
 double angle,
 double scale)

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

Parameters:

sop - the source operation

angle - the angle of rotation, in degrees

scale - the scale factor

RotateScaleOpBitmapImpl

public RotateScaleOpBitmapImpl(ImageOp sop,
 double angle,
 double scale,
 RenderingHints hints)

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

Parameters:

sop - the source operation

angle - the angle of rotation, in degrees

scale - the scale factor

hints - rendering hints

Throws:

IllegalArgumentException - if sop == null.
