array_to_cimg

Automatic, semi-automatic, and manual functions for
generating color maps from images. The idea is to simplify
the colors of an image according to a metric that is useful for
the user, using deterministic methods whenever possible.
Many images will be clustered well using the out-of-the-box
functions, but the package also includes a toolbox of functions
for making manual adjustments (layer merging/isolation, blurring,
fitting to provided color clusters or those from another image, etc).
Also includes export methods for other color/pattern analysis packages
(pavo, patternize, colordistance).

array_to_cimg function

<dl><dt>x</dt>
<dd>An image array, i.e. as read in by readPNG.</dd>
<dt>flatten_alpha</dt>
<dd>Logical. Flatten the alpha channel?</dd>
<dt>bg</dt>
<dd>Passed to <code>imager::flatten.alpha()</code>. Pixel color for
previously transparent pixels.</dd>
<dt>rm_alpha</dt>
<dd>Logical. Remove the alpha channel?
Note this will "reveal" whatever is hidden behind
the transparent pixels, rather than turn them white.</dd></dl>
