Constructor & Destructor Documentation

AviReader::AviReader	(	char const *	name,
		VideoArray< coeff > *	arrays[],
		int	rawy,
		int	rawx,
		int	from,
		int	to
	)

Constructor. Only calls the mother class' constructor to initialize the {ImageArray} reference. All frames in the ranges must be of the same size.

Parameters:

name	the file name
arrays	the array of video arrays for the values
rawy	the number of rows
rawx	the number of cols
from	one greater than the last frame, if equal to `from' then the whole video will be read, if 0, then the video will be read from `from' to the end
to	the last frame

Member Function Documentation

static void AviReader::fileDimensions	(	const char *	fname,
		int &	y,
		int &	x
	)		[static]

Calculates the frame dimensions in a file.

Exceptions:

invalid_argument

if the file cannot be read

Parameters:

fname	the file name
y	the returned number of rows
x	the returned number of columns

static double AviReader::frameRate

(

const char *

fname

)

[static]

Calculates the frame rate.

Exceptions:

invalid_argument

if the file cannot be read

Parameters:

fname

the file name

Returns:

the frame rate

static int AviReader::framesInFile

(

const char *

fname

)

[static]

Calculates the number of frames in a file.

Exceptions:

invalid_argument

if the file cannot be read

Parameters:

fname

the file name

Returns:

the number of frames

virtual int AviReader::readfmt

(

void

)

[protected, virtual]

Read the VID file format. This does the actual work of reading and parsing the image file. It gets called by the {read ()} method.

Returns:

0 if successful, -1 on read error, -2 on file format error.

Implements VideoReader.
