ResizeWithCropOrPadOp class

As a computation unit for processing images, it could resize image to predefined size.

It will not stretch or compress the content of image. However, to fit the new size, it crops or pads pixels. When it crops image, it performs a center-crop; when it pads pixels, it performs a zero-padding.

See ResizeOp for resizing images while stretching / compressing the content.

Constructors

ResizeWithCropOrPadOp(int _targetHeight, int _targetWidth, [int? _cropLeft, int? _cropTop])
Creates a ResizeWithCropOrPadOp which could crop/pad images to height: _targetHeight & width: _targetWidth. It adopts center-crop and zero-padding. You can pass whith _cropLeft and _cropTop top-left position of a crop to overide the default centered one.
