Method Details

boundBox

public static RectangleLength2D_I32 boundBox(int srcWidth,
 int srcHeight,
 int dstWidth,
 int dstHeight,
 Point2D_F32 work,
 PixelTransform<Point2D_F32> transform)

Finds an axis-aligned bounding box which would contain a image after it has been transformed. A sanity check is done to made sure it is contained inside the destination image's bounds. If it is totally outside then a rectangle with negative width or height is returned.

Parameters:

srcWidth - Width of the source image

srcHeight - Height of the source image

dstWidth - Width of the destination image

dstHeight - Height of the destination image

transform - Transform being applied to the image

Returns:

Bounding box

boundBox

public static RectangleLength2D_I32 boundBox(int srcWidth,
 int srcHeight,
 Point2D_F32 work,
 PixelTransform<Point2D_F32> transform)

Finds an axis-aligned bounding box which would contain a image after it has been transformed. The returned bounding box can be larger then the original image.

Parameters:

srcWidth - Width of the source image

srcHeight - Height of the source image

transform - Transform being applied to the image

Returns:

Bounding box

boundBox_F32

public static RectangleLength2D_F32 boundBox_F32(int srcWidth,
 int srcHeight,
 PixelTransform<Point2D_F32> transform,
 Point2D_F32 transformed)

Finds an axis-aligned bounding box which would contain a image after it has been transformed. The returned bounding box can be larger then the original image.

Parameters:

srcWidth - Width of the source image

srcHeight - Height of the source image

transform - Transform being applied to the image

Returns:

Bounding box

boundBox_F64

public static RectangleLength2D_F64 boundBox_F64(int srcWidth,
 int srcHeight,
 PixelTransform<Point2D_F64> transform,
 Point2D_F64 transformed)

Finds an axis-aligned bounding box which would contain a image after it has been transformed. The returned bounding box can be larger then the original image.

Parameters:

srcWidth - Width of the source image

srcHeight - Height of the source image

transform - Transform being applied to the image

Returns:

Bounding box
