transparent
Paints markers in a transparent version of their selected colour. The degree of transparency is determined by how many points are plotted on top of each other and by the opaque limit. The opaque limit fixes how many points must be plotted on top of each other to completely obscure the background. This is set to a fixed value, so a transparent level that works well for a crowded region (or low magnification) may not work so well for a sparse region (or when zoomed in).
Usage:
shadingN=transparent colorN=<rrggbb>|red|blue|... opaqueN=<number>
All the parameters listed here
affect only the relevant layer,
identified by the suffix
N
.
Associated parameters are as follows:
colorN = <rrggbb>|red|blue|...
(Color)
The value may be a six-digit hexadecimal number
giving red, green and blue intensities,
e.g. "ff00ff
" for magenta.
Alternatively it may be the name of one of the
pre-defined colors.
