imwrite(A,filename,fmt) writes the image in A to filename in the format specified by fmt. A can be either a grayscale image (M-by-N) or a truecolor image (M-by-N-by-3). filename is a string that specifies the name of the output file. Empty image data is not allowed. The possible values for fmt are determined by the MATLAB file format registry.
>> %read an Image >> im = imread('DesertSmall.jpg'); >> % Syntax : imwrite(<image>,<name of new image>,<new image format>) >> imwrite(im,'newImage.png','png')
