आकारों पर 3D प्रभाव और छायाएँ कैसे लागू करें

आकारों पर 3D प्रभाव और छायाएँ कैसे लागू करें

Aspose.Slides FOSS प्रत्येक आकार पर दो स्वतंत्र प्रभाव प्रणालियाँ प्रदान करता है:

  • shape.getEffectFormat(): 2D दृश्य प्रभाव: outer shadow, glow, blur, soft edge
  • shape.getThreeDFormat(): 3D उपस्थिति: bevel, camera perspective, light rig, material, depth

दोनों सिस्टम को एक ही आकार पर संयोजित किया जा सकता है।
