Şekillere 3D Efektler ve Gölgeler Uygulama

Aspose.Slides FOSS, her şekil üzerinde iki bağımsız efekt sistemi sağlar:

  • shape.effect_format: 2D görsel efektler: dış gölge, parıltı, bulanıklaştırma, yumuşak kenar
  • shape.three_d_format: 3D görünüm: köşe, kamera perspektifi, ışık donanımı, malzeme, derinlik

Her iki sistem aynı şekil üzerinde birleştirilebilir.

Önkoşullar 

pip install aspose-slides-foss

Dış Düşen Gölge Ekle 

from aspose.slides_foss import ShapeType
from aspose.slides_foss.drawing import Color
import aspose.slides_foss as slides
from aspose.slides_foss.export import SaveFormat

with slides.Presentation() as prs:
    shape = prs.slides[0].shapes.add_auto_shape(
        ShapeType.RECTANGLE, 100, 100, 300, 120
    )
    shape.add_text_frame("Shadowed Shape")

    ef = shape.effect_format
    ef.enable_outer_shadow_effect()
    ef.outer_shadow_effect.blur_radius = 10       # softness in points
    ef.outer_shadow_effect.direction = 315        # 315° = upper-left
    ef.outer_shadow_effect.distance = 8           # offset in points
    ef.outer_shadow_effect.shadow_color.color = Color.from_argb(128, 0, 0, 0)

    prs.save("shadow.pptx", SaveFormat.PPTX)

Ortak direction değerleri: 0=sağ, 45=sağ-alt, 90=aşağı, 180=sol, 270=yukarı, 315=sol-üst.

Parıltı Efekti Ekle 

from aspose.slides_foss import ShapeType
from aspose.slides_foss.drawing import Color
import aspose.slides_foss as slides
from aspose.slides_foss.export import SaveFormat

with slides.Presentation() as prs:
    shape = prs.slides[0].shapes.add_auto_shape(
        ShapeType.ELLIPSE, 150, 100, 250, 250
    )

    ef = shape.effect_format
    ef.enable_glow_effect()
    ef.glow_effect.radius = 20
    ef.glow_effect.color.color = Color.gold

    prs.save("glow.pptx", SaveFormat.PPTX)

Gauss Bulanıklığı Uygula 

from aspose.slides_foss import ShapeType
import aspose.slides_foss as slides
from aspose.slides_foss.export import SaveFormat

with slides.Presentation() as prs:
    shape = prs.slides[0].shapes.add_auto_shape(
        ShapeType.RECTANGLE, 100, 100, 350, 180
    )
    shape.effect_format.set_blur_effect(radius=10, grow=True)

    prs.save("blur.pptx", SaveFormat.PPTX)

grow=True bulanıklaştırma bölgesini şekil sınırının ötesine genişletir; grow=False bulanıklaştırmayı şeklin içine kırpar.

3D Kenar Uygula 

from aspose.slides_foss import ShapeType, BevelPresetType

        ShapeType.RECTANGLE, 150, 150, 280, 120
    )
    shape.add_text_frame("3D Button")

    tdf = shape.three_d_format
    tdf.bevel_top.bevel_type = BevelPresetType.CIRCLE
    tdf.bevel_top.width = 12
    tdf.bevel_top.height = 6

    prs.save("bevel.pptx", SaveFormat.PPTX)

BevelPresetType değerleri: CIRCLE, RELAXED_INSET, COOL_SLANT, DIVOT, RIBLET, HARD_EDGE, SLOPE, CONVEX

Kamera ve Işık Donanımıyla 3D Bevel

    # Solid fill
    shape.fill_format.fill_type = FillType.SOLID
    shape.fill_format.solid_fill_color.color = Color.from_argb(255, 30, 80, 180)

    # 3D bevel
    tdf = shape.three_d_format
