- * Extract any icc profiles found in the given PNG files. This is a simple
- * example of a program which extracts information from the header of a PNG file
- * without processing the image. Notice that some header information may occur
- * after the image data, textual data and comments are an example; the approach
- * in this file won't work reliably for such data because it only looks for the
- * information in the section of the file that preceeds the image data.
- *
- * Compile and link against libpng and zlib, plus anything else required on the
- * system you use.
- *
- * To use supply a list of PNG files containing iCCP chunks, the chunks will be
- * extracted to a similarly named file with the extension replaced by 'icc',
- * which will be overwritten without warning.
