sng_regress1

Usage

Overview

The sng_regress program is designed to help with regression testing of the sng minilanguage.

Given SNG and PNG input files, sng_regress will do round-trip conversions (SNG->PNG->SNG or vice-versa), and then compare the results. For PNG files, it is possible to visually verify the results.

Options

-s

Stop on any regression failure. By default, errors are reported, but all files given on the command line are processed.

-e

Manually 'eyeball' the result of PNG regression tests. The resulting is displayed with display which is part of the ImageMagick package.
