Bilderserien mit gleicher Höhe und Breite
Abgelegt unter
—
Hier eine Methode, wie man mit reinem TypoScript eine Serie mit Bildern erzeugen kann, die immer die gleiche Höhe und Breite haben. Dabei werden die Bilder nur beschnitten, wenn es sein muss - und nur so viel, wie es sein muss. Verwendung: z.B. in Slideshows, Gallerien etc.
Die Bilder werden in diesem Beispiel aus dem Resourcen-Feld einer bestimmten Seite ausgelesen.
