insert_shape

insert_shape(im, element, center=None, corner=None, value=1, mode='overwrite')[source]

Inserts sub-image into a larger image at the specified location.

If the inserted image extends beyond the boundaries of the image it will be cropped accordingly.

Parameters:

  • im (ndarray) – The image into which the sub-image will be inserted

  • element (ndarray) – The sub-image to insert

  • center (tuple) – Coordinates indicating the position in the main image where the inserted imaged will be centered. If center is given then corner cannot be specified. Note that center can only be used if all dimensions of element are odd, otherwise the meaning of center is not defined.

  • corner (tuple) – Coordinates indicating the position in the main image where the lower corner (i.e. [0, 0, 0]) of the inserted image should be anchored. If center is given then corner cannot be specified.

  • value (scalar) – A scalar value to apply to the sub-image. The default is 1.

  • mode (string) – If ‘overwrite’ (default) the inserted image replaces the values in the main image. If ‘overlay’ the inserted image is added to the main image. In both cases the inserted image is multiplied by value first.

Returns:

im – A copy of im with the supplied element inserted.

Return type:

ndarray
