How did you open the file? On Windows you must open a file explicitly as text or binary - one of them is the default, but who knows ? ;-) I'd guess the default is text, and you need the binary open for PNG files, like outfile = fopen (filename, "wb"); Otherwise all LF characters (binary 10) would be converted to CR/LF on write.
