Constructs and returns a formatted output file name.

The file name is formatted as follow:

`filename_prefix`_`id`_`filename`_`postfix_id`

Where:

`filename_prefix` can be set through the global variable debug::internal::filename_prefix.
`id` is auto-incremented and cannot be controlled.
`filename` is the given filename
`postfix_id` is an optional counter which can be controlled contrary to `id`.

signed short mln::debug::format ( signed char v ) [inline]

Format a signed char to print it properly, i.e., like an integer value.

unsigned short mln::debug::format ( unsigned char v ) [inline]

Format an unsigned char to print it properly, i.e., like an integer value.

template<typename T >

const T & mln::debug::format ( const T & v ) [inline]

Default version for formatting a value is a no-op.

	)

Superpose two images.

Parameters:

`[in]`	input_	An image. Its value type must be convertible toward value::rgb8 thanks to a conversion operator or convert::from_to.
`[in]`	object_	A binary image. Objects used for superposition are set to 'true'.
`[in]`	object_color	The color used to draw the objects in `object_`.

Precondition:: input_ and object_ must have the same domain.

Returns:: A color image.
