Save a numpy array to an image on disk
SYNOPSIS
print(image.shape)
---> (768, 1024, 3)
print(image.dtype)
---> dtype('uint8')
mrcal.save_image("result.png", image)
# wrote BGR color image to disk
This is a completely uninteresting image-saving routine. It's like any other
image-saving routine out there; use any that you like. This exists because cv2
is very slow.
This wraps the mrcal_image_TYPE_save() functions. At this time I support only
these 3 data formats:
- bpp = 8, channels = 1: 8-bit grayscale data
- bpp = 16, channels = 1: 16-bit grayscale data
- bpp = 24, channels = 3: BGR color data
ARGUMENTS
- filename: the image on disk to save to
- array: numpy array containing the input data. Must have shape (height,width)
for grayscale data or (height,width,3) for color data. Each row must be stored
densely, but a non-dense stride is supported when moving from column to
column. The dtype must be either np.uint8 or np.uint16.
RETURNED VALUE
None on success. Exception thrown on error
