Radiale Schattierung ändern

Ich versuche, die angegebene radiale Schattierung zu ändern:

Ich möchte die radiale Schattierung erhöhen, damit die weiße Füllung größer wird.

Der Code zeigt:

A

Gibt es eine andere Art der Schattierung? Rechteckig? Wie geht das?

Antwort1

Der Schlüssel zum Ändern einer radialen Schattierung ist \pgfdeclareradialshading, siehe das pgfHandbuch unter109.2.2 Radial Shadings

\pgfdeclareradialshading[inner color,middle color, outer color]{ustanakradial}{\pgfpoint{0.0cm}{0.0cm}}%
{ color(0)=(inner color);
  color(10bp)=(middle color);
  color(28bp)=(outer color)
}

Dies definiert eine radiale Schattierung namens ustanakradialmit einigen symbolischen Farbnamen, die auf die Kreise mit den entsprechenden Radien angewendet werden. Die Werte von 10ptund 28ptsind nur „Vermutungen“. Übertreiben Sie sie nicht.

Der Mittelpunkt der Schattierung wird hier fest auf gesetzt \pgfpoint{0cm}{0cm}.
