get what to write in the XLIST / YLIST definitions. I just do not understand the documentation of the cht-format here. The reference edges - is it the borders between the color patches? The chart has 6x4 patches, so should I write the centerline of the 5 vertical and 3 horizontal edges here?
It's really any vertical or horizontal edges in the chart. These are the features that are used to orient then align the patch template with the image. Running scanin -g (See <http://www.argyllcms.com/doc/scanin.html#g>) is a way of generating an initial template, although it will then need augmenting and cleaning up by hand. Graeme Gill.
