requires
- image_type == an image object that implements the interface defined in
dlib/image_processing/generic_image.h or a matrix expression
- image.size() != 0
- 0 <= quality <= 100
ensures
- writes the image to the file indicated by file_name in the JPEG format.
- image[0][0] will be in the upper left corner of the image.
- image[image.nr()-1][image.nc()-1] will be in the lower right corner of the
image.
- This routine can save images containing any type of pixel. However,
save_jpeg() can only natively store rgb_pixel and uint8 pixel types. All
other pixel types will be converted into one of these types as appropriate
before being saved to disk.
- The quality value determines how lossy the compression is. Larger quality
values result in larger output images but the images will look better.
throws
- image_save_error
This exception is thrown if there is an error that prevents us from saving
the image.
- std::bad_alloc
