The left coordinate, which must be in [0,getWidth())
The top coordinate, which must be in [0,getHeight())
The width of the rectangle to crop.
The height of the rectangle to crop.
A cropped version of this object.
Converts a 2D array of luminance data to 1 bit. As above, assume this method is expensive and do not call it repeatedly. This method is intended for decoding 2D barcodes and may or may not apply sharpening. Therefore, a row from this matrix may not be identical to one fetched using getBlackRow(), so don't mix and match between them.
The 2D array of bits for the image (true means black).
Converts one row of luminance data to 1 bit data. May actually do the conversion, or return cached data. Callers should assume this method is expensive and call it as seldom as possible. This method is intended for decoding 1D barcodes and may choose to apply sharpening.
The row to fetch, which must be in [0, bitmap height)
An optional preallocated array. If null or too small, it will be ignored. If used, the Binarizer will call BitArray.clear(). Always use the returned object.
The array of bits for this row (true means black).
The height of the bitmap.
The width of the bitmap.
Whether this bitmap can be cropped.
Whether this bitmap supports counter-clockwise rotation.
Returns a new object with rotated image data by 90 degrees counterclockwise. Only callable if {@link #isRotateSupported()} is true.
A rotated version of this object.
Returns a new object with rotated image data by 45 degrees counterclockwise. Only callable if {@link #isRotateSupported()} is true.
A rotated version of this object.
Generated using TypeDoc
Returns a new object with cropped image data. Implementations may keep a reference to the original data rather than a copy. Only callable if isCropSupported() is true.
