Allocate matrix for movie frames
Syntax
M=
moviein(n) M
=
moviein(n,
h
) M=
moviein(n,
h
,rect)
Description
moviein
allocates an appropriately sized matrix for the getframe
function.
M = moviein(n)
creates matrix M
having n
columns to store n
frames of a movie based on the size of the current axes.
M = moviein(n,h)
specifies a handle for a valid figure or axes graphics object on which to base the memory requirement. You must use the same handle with getframe
. If you want to capture the axis in the frames, specify h
as the handle of the figure.
M = moviein(n,h,rect)
specifies the rectangular area from which to copy the bitmap, relative to the lower-left corner of the figure or axes graphics object identified by h
. rect = [left bottom width height]
, where left
and bottom
specify the lower-left corner of the rectangle, and width
and height
specify the dimensions of the rectangle. Components of rect
are in pixel units. You must use the same handle and rectangle with getframe
.
Remarks
moviein
is no longer meeded as of MATLAB Release 11 (5.3). In earlier versions, pre-allocating a movie increased performance, but there is no longer a need to do this.
