The style is simply the name of a subdirectory under images/arrows, that holds an alternate copy of the arrow graphics.

If it doesn't exist or has missing images, you'll get "under construction" symbols instead of arrow graphics.

◆ set_color()

void arrow::set_color ( const std::string & color )

virtual

The string color parameter is in the same format expected by the image::locator modifiers parameter.

Examples: red is "red" or "FF0000" or "255,0,0". Feel free to add another method that accepts an uint32_t as a parameter instead.
