Allows to use a source of TrueType characters to define the marker that will
substitute the symbol.If the picture is defined in a source, the performance is
more agile.
Creates a new instance of CharacterMarker specifying the marker source
font, the character code corresponding to the symbol, and the color that
will be used in rendering time.
Calculates the distance in pixels corresponding to the provided length,
according to the current rendering context (output dpi, map scale, map units) and the
symbol cartographic settings (unit, size, and unit reference system).
Returns true of false depending if the character marker symbol selected is visually
corrected.That is, if the character has been properly scaled to use a specific number
of pixels to be represented.
Class used to create symbols composed using a text defined by
the user.This text can be edited (changing the color, the font of the characters, and
the rotation of the text)and has the property that can follow a path.If this path
does not exist, the text is treated as a simpletextsymbol (when is drawn).
