2.1.18. Distribution type

---

The distribution type combo-box allows you to change the distribution algorithm type.

• Uniform distribution is a flat distribution.
• Normal distribution is a bell curve distribution.
• Source distribution preserves the analyzed source histogram shape while mapping into your configured target range.
• Reference distribution matches the histogram shape of a second analyzed file.

Normal distribution can be skewed using the distribution skew parameter.

Source distribution is useful when you want to compress or expand while keeping the original histogram shape.

Reference distribution requires loading a reference file after source analysis and before optimization. After loading, target range is initialized from the reference file’s equivalent range and is re-synced when source percentiles change.
