Function Documentation

mirm_image_alloc_data()

mirkl_error_t * mirm_image_alloc_data	(	mirm_image_t *	img,
		mirkl_uint32_t	width,
		mirkl_uint32_t	length,
		unsigned int	dt,
		mirkl_bool_t	set_data_model
	)

Allocate double data for an image. The size of the image is set to width-x-length.

mirm_image_copy()

mirkl_error_t * mirm_image_copy	(	mirm_image_t *	img_src,
		mirm_image_t *	img_cpy,
		mirkl_bool_t	copy_data
	)

Copy image img_src to img_cpy.

mirm_image_free_data()

void mirm_image_free_data	(	mirm_image_t *	img,
		unsigned int	dt
	)

Delete (free memory) all data allocated for this image.

mirm_image_instance_create()

mirkl_error_t * mirm_image_instance_create	(	mirkl_object_t **	obj,
		mirkl_uint32_t	flags,
		mir_prsdata_t *	pp,
		apr_pool_t *	pool,
		apr_pool_t *	tmp_pool
	)

Creation of Image object.

Parameters

[out]	obj	Reference to the created object.
	flags	Flags of the object.
	pp	Reference to the parser data structure.
	pool	The pool to use for allocations of object structures. Should be valid as long as the created object lives.
	tmp_pool	The pool for temporary allocations. Can be deleted after calling this function.

mirm_image_instance_create_imgcpy()

mirkl_error_t * mirm_image_instance_create_imgcpy	(	mirkl_object_t **	obj,
		mirm_image_t *	img_src,
		mirkl_uint32_t	flags,
		mir_prsdata_t *	pp,
		apr_pool_t *	pool,
		apr_pool_t *	tmp_pool
	)

Creation of Image object by copying from another image.

Parameters

img_src

Already initialized image, which should be copied to the newly created image. All other parameters are the same as in mirm_image_instance_create().

mirm_image_multiply_img()

mirkl_error_t * mirm_image_multiply_img	(	mirm_image_t *	img,
		mirm_image_t *	img_b
	)

Muplitply image by image pixelwise. Active mask and area are taken into account.

Parameters

[in,out]	img	The image, whose pixel values must be multiplied.
[in]	img_b	The image, whose pixel values are used as factors in multiplication.

Note

Dimensions of images must be equal.

mirm_image_subtract_d()

mirkl_error_t * mirm_image_subtract_d	(	mirm_image_t *	img,
		double	val
	)

Subtract double floating point value from image. Active mask and area are taken into account.

mirm_image_subtract_img()

mirkl_error_t * mirm_image_subtract_img	(	mirm_image_t *	img,
		mirm_image_t *	img_b
	)

Subtract image from image pixelwise. Active mask and area are taken into account.

Parameters

[in,out]	img	Image, from which pixel values must be subtracted.
[in]	img_b	Image, whose pixel values must be subtracted from values of img.

Note

Dimensions of images must be equal.
