Function Documentation

gboolean iw_img_allocate ( iwImage * img )

Allocate memory for img->data and img->data[] according to the
other settings in img.
Return: TRUE if memory could be allocated.

gboolean iw_img_alloc_planeptr ( iwImage * img )

Allocate memory only for img->data (and NOT img->data[]) according
to the other settings in img.
Return: TRUE if memory could be allocated.

void iw_img_init ( iwImage * img )

Initialise image img by setting everything to 0.
Do NOT allocate any memory.

iwImage* iw_img_new ( void )

Allocate a new image and set everything to 0. -> Do NOT allocate
any image data.

iwImage* iw_img_new_alloc	(	int	width,
		int	height,
		int	planes,
		iwType	type
	)

Allocate and initialise a new img and allocate memory for
img->data and img->data[].

void iw_img_free	(	iwImage *	img,
		iwImgFree	what
	)

Free parts of the image. 'what' specifies what to free.

void iw_img_copy_ctab	(	const iwImage *	src,
		iwImage *	dst
	)

If src has an own indexed color tabel, allocate a new one for dst
and copy the table. Otherwise set the ctab entry of dst to the one
of src.

iwImage* iw_img_copy	(	const iwImage *	src,
		iwImage *	dst
	)

Copy src to dst, allocate all plane pointer, planes, and color
tables, and return a pointer to dst, or NULL on error (no mem).

iwImage* iw_img_duplicate ( const iwImage * img )

Return a copy of the image img. All plane pointer, planes, and
color tables are also copied.

iwImage* iw_img_load	(	const char *	fname,
		iwImgStatus *	status
	)

Load image from file fname in 'planed' form.

iwImage* iw_img_load_interleaved	(	const char *	fname,
		iwImgStatus *	status
	)

Load image from file fname and return an interleaved image.

void iw_movie_close ( iwMovie * movie )

Close movie file if it is != NULL and free all associated data.

iwMovie* iw_movie_open	(	const char *	fname,
		iwImgStatus *	status
	)

Open the movie file fname for reading.

iwImage* iw_movie_read	(	iwMovie **	movie,
		const char *	fname,
		int	frame,
		iwImgStatus *	status
	)

Open the movie 'fname' (if not already open) and return its frame
'frame'.
ATTENTION: The returned frame is a pointer to an internally used
image which is freed by iw_movie_close().

float iw_movie_get_framerate ( const iwMovie * movie )

Return frame rate of 'movie'.

int iw_movie_get_framecnt ( const iwMovie * movie )

Return number of frames of 'movie'.

int iw_movie_get_framepos ( iwMovie * movie )

Return the number of the frame, which was the result of the
last call to iw_movie_read()

iwImgFileData* iw_img_data_create ( void )

Initialise struct holding settings for saving images.

void iw_img_data_free ( iwImgFileData * data )

Free struct created with iw_img_create_data().

void iw_img_data_set_movie	(	iwImgFileData *	data,
		iwMovie **	movie,
		float	framerate
	)

Set parameters used for MOVIE saving.

void iw_img_data_set_quality	(	iwImgFileData *	data,
		int	quality
	)

Set quality parameter (used for JPEG saving),

iwImgFormat iw_img_save_get_format	(	iwImgFormat	format,
		const char *	fname
	)

If 'format' == IW_IMG_FORMAT_UNKNOWN return a format based on the
extension of fname. Otherwise return 'format'.

iwImgStatus iw_img_save	(	const iwImage *	img,
		iwImgFormat	format,
		const char *	fname,
		const iwImgFileData *	data
	)

Save 'img' in file 'fname' in the format 'format'. If
'format' == IW_IMG_FORMAT_UNKNOWN the extension of fname is used.
