Εργασία με 3D εφέ και οπτικά αποτελέσματα Aspose.Slides FOSS για Python

Aspose.Slides FOSS for Python provides two separate effect systems accessible on every shape:

  • EffectFormat (shape.effect_format2): 2D οπτικά αποτελέσματα: σκιά, λάμψη, μαλακό άκρο, μπλουρίδα, αντανακλά
  • ThreeDFormat (shape.three_d_format): 3D εμφάνιση: βέβλος, προβολή κάμερας, φωτεινό χαλί, υλικό, βάθος εξόρυξης

Και τα δύο συνεχίζονται μέσω κύκλων αποθήκευσης / επαναφόρτωσης.
