#### `plscmap0a`: Set cmap0 colors by 8-bit RGB values and PLFLT alpha transparency value

`plscmap0a (` | r ,
| g ,
| b ,
| alpha ,
| ncol0 `)`;

Set cmap0 colors using 8-bit RGB values (see the section called “Color Map0”) and PLFLT alpha transparency value. This sets the entire color map – only as many colors as specified will be allocated.

`r` (``PLINT_VECTOR``, input)

  A vector containing unsigned 8-bit integers (0-255) representing the degree of red in the color.

`g` (``PLINT_VECTOR``, input)

  A vector containing unsigned 8-bit integers (0-255) representing the degree of green in the color.

`b` (``PLINT_VECTOR``, input)

  A vector containing unsigned 8-bit integers (0-255) representing the degree of blue in the color.

`alpha` (``PLFLT_VECTOR``, input)

  A vector containing values (0.0-1.0) representing the alpha transparency of the color.

`ncol0` (``PLINT``, input)

  Number of items in the ``r`` , ``g`` , ``b`` , and ``alpha`` vectors.

Redacted form: `plscmap0a(r, g, b, alpha)`

This function is used in examples 30.
