Similar to imwrite, except follows a strict naming convention.
Wrapper for imwrite that writes file to the filename:
imagename = [path name int2str2(i,ndigits) '.' ext];
Using imwrite:
imwrite( I, imagename, writeparams )
If I represents a stack of images, the ith image is written to:
imagenamei = [path name int2str2(i+imagei-1,ndigits) '.' ext];
If I=[], then imwrite2 will attempt to read images from disk instead.
multflag controls how I is interpreted. If multflag==0, then I is intrepreted as a
single image, otherwise I is interpreted as a stack of images, where I(:,:,...,j)
represents the jth image (see feval_arrays for more info).
If the directory specified by 'path' does not exist, imwrite2 attempts to create it.
INPUTS
I - image or array or cell of images (if [] reads else writes)
multflag - set to 1 if I represents a stack of images
imagei - first image number
path - directory where images are
name - base name of images
ext - extension of image
ndigits - number of digits for filename index
writeparams - [varargin] additional parameters to imwrite
OUTPUTS
I - image or images (read from disk if input I=[])
EXAMPLE
load images; clear IDXi IDXv t video videos;
imwrite2( images(:,:,1), 0, 0, 'rats/', 'rats', 'png', 5 ); % writes first frame
imwrite2( images(:,:,1:5), 1, 0, 'rats/', 'rats', 'png', 5 ); % writes first 5 frames
images2 = imwrite2( [], 1, 0, 'rats/', 'rats', 'png', 5 ); % reads first 5 frames
images2 = feval_images(@(x) x,{},'rats/','rats','png',0,4,5); % reads first 5 frames
