length (srcfile);
Here, srcfile is an image. the previous line determines the length of an image but I don't understand what can be the length of an image!!
Can anyone help me please to understand it.
Thanks

From Matlab point of view, an image is a matrix (sometimes a 3D matrix). if Im is the matrix containing your image,
length(Im)
will return the number of columns of the image matrix.
size(Im)
returns both rows and columns.

The name "scrFile" seems to imply, that this is the name of the image file. Then length(srcFile) replies the number of characters of this name.
