v7 -equalize with -channel
Posted: 2016-05-17T10:02:16-07:00
In v6, "-equalize" is sensitive to "-channel", so we could equalize channels independently.
In v7, a "-channel" setting does not affect the behaviour of "-equalize". I assume this is a bug.
For example, where %IM% is v6.9.2-5 and %IMG7% is v7.0.1-3:
Input toes.jpg:

Output v6 without channel setting:

Output v6 with channel setting:

Output v7 without channel setting:

Output v7 with channel setting:

The v7 outputs are the same as each other, and the same as v6 without the channel setting.
