CropToSquare

public CropToSquare()

Method Details

getRegion

public Region getRegion(Size reducedSize,
 ReductionFactor reductionFactor,
 ScaleConstraint scaleConstraint)

Description copied from class: Crop

Computes an effective crop rectangle in source image coordinates.

Specified by:

getRegion in class Crop

Parameters:

reducedSize - Size of the input image, reduced by reductionFactor.

reductionFactor - Factor by which the full-sized image has been reduced to become reducedSize.

scaleConstraint - Scale constraint yet to be applied to the input image. The instance is expressed relative to this constraint rather than to reducedSize or the full image size.

Returns:

Region relative to the given reduced dimensions.

hasEffect

public boolean hasEffect()

May produce false positives. hasEffect(Size, OperationList) should be used instead where possible.

Specified by:

hasEffect in interface Operation

Specified by:

hasEffect in class Crop

Returns:

Whether the crop is not effectively a no-op.

hasEffect

public boolean hasEffect(Size fullSize,
 OperationList opList)

Description copied from interface: Operation

Context-aware counterpart to Operation.hasEffect(). For example, a scale operation specifying a scale to 300×200, when the given operation list contains a crop of 300×200, would return false.

Specified by:

hasEffect in interface Operation

Specified by:

hasEffect in class Crop

Parameters:

fullSize - Full size of the source image.

opList - Operation list of which the operation may or may not be a member.

Returns:

Whether the crop is not effectively a no-op.

toString

public String toString()

Overrides:

toString in class Object
