| MIME-Version: 1.0 |
| Content-Type: text/plain; charset=UTF-8 |
| Content-Transfer-Encoding: 8bit |

| The HGT is a Histogram Generator Two-Dimensions. It computes a weighted |
| frequency histograms for hue and saturation areas over a configurable |
| region of the image with optional subsampling. |
