## NAME

Image::makePNG - Output a PNG.

## SYNOPSIS

**Void makePNG(** *Image img, String file=""* **)**

## ARGUMENTS

**img** The image

**file** The file name to write to. This argument may be omitted to use standard output, which is useful in CGI scripts - call **CGI.flush (3kaya)** first to ensure the headers have been sent.

## DESCRIPTION
