Aspose.Slides FOSS for Python lets you apply professional-quality visual effects to PowerPoint shapes entirely in Python, with no Microsoft Office and no API keys. This post demonstrates the fill system, 2D effects, and 3D formatting available in the library.
Het vullingssysteem
Elke vorm heeft een fill_format die bepaalt hoe het interieur wordt geschilderd. De vijf opvultypen dekken het volledige bereik van het ontwerppalet van PowerPoint.
Solide vulling
De eenvoudigste vulling, een effen kleur met optionele transparantie:
from aspose.slides_foss import ShapeType, FillType
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.ROUND_CORNER_RECTANGLE, 100, 100, 400, 150
)
shape.add_text_frame("Solid Fill")
shape.fill_format.fill_type = FillType.SOLID
shape.fill_format.solid_fill_color.color = Color.from_argb(255, 30, 80, 180)
prs.save("solid.pptx", SaveFormat.PPTX)
Lineaire verloopvulling
Verloopstops laten je van de ene kleur naar de andere overgaan over de vorm:
from aspose.slides_foss import ShapeType, FillType, GradientShape
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, 400, 150
)
ff = shape.fill_format
ff.fill_type = FillType.GRADIENT
gf = ff.gradient_format
gf.gradient_shape = GradientShape.LINEAR
gf.linear_gradient_angle = 90 # top-to-bottom
gf.gradient_stops.add(0.0, Color.from_argb(255, 30, 80, 180)) # top: blue
gf.gradient_stops.add(1.0, Color.from_argb(255, 0, 200, 160)) # bottom: teal
prs.save("gradient.pptx", SaveFormat.PPTX)
2D Visual Effects
Buitenste slagschaduw
Bevestig een halftransparante slagschaduw aan elke vorm:
from aspose.slides_foss import ShapeType, FillType
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.ROUND_CORNER_RECTANGLE, 100, 100, 350, 150
)
shape.add_text_frame("Drop Shadow")
shape.fill_format.fill_type = FillType.SOLID
shape.fill_format.solid_fill_color.color = Color.white
ef = shape.effect_format
ef.enable_outer_shadow_effect()
ef.outer_shadow_effect.blur_radius = 12
ef.outer_shadow_effect.direction = 315 # upper-left
ef.outer_shadow_effect.distance = 8
ef.outer_shadow_effect.shadow_color.color = Color.from_argb(100, 0, 0, 0)
prs.save("shadow.pptx", SaveFormat.PPTX)
Gloeieffect
Een gekleurde halo rond de rand van de vorm:
from aspose.slides_foss import ShapeType, FillType
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
)
shape.fill_format.fill_type = FillType.SOLID
shape.fill_format.solid_fill_color.color = Color.from_argb(255, 20, 60, 140)
ef = shape.effect_format
ef.enable_glow_effect()
ef.glow_effect.radius = 20
ef.glow_effect.color.color = Color.from_argb(200, 0, 180, 255)
prs.save("glow.pptx", SaveFormat.PPTX)
3D Formatting
Bevel en Materiaal
De three_d_format eigenschap geeft elke platte vorm een driedimensionaal uiterlijk. Combineer een afschuining met een camera‑preset en een materiaal voor het rijkste resultaat:
from aspose.slides_foss import (
ShapeType, FillType,
BevelPresetType, CameraPresetType,
LightRigPresetType, LightingDirection,
MaterialPresetType,
)
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, 150, 150, 300, 130
)
shape.add_text_frame("Metal Button")
# Blue solid fill
shape.fill_format.fill_type = FillType.SOLID
shape.fill_format.solid_fill_color.color = Color.from_argb(255, 20, 70, 160)
# 3D bevel + camera + light + material
tdf = shape.three_d_format
tdf.bevel_top.bevel_type = BevelPresetType.CIRCLE
tdf.bevel_top.width = 10
tdf.bevel_top.height = 5
tdf.camera.camera_type = CameraPresetType.PERSPECTIVE_ABOVE
tdf.light_rig.light_type = LightRigPresetType.BALANCED
tdf.light_rig.direction = LightingDirection.TOP
tdf.material = MaterialPresetType.METAL
tdf.depth = 20
prs.save("metal-button.pptx", SaveFormat.PPTX)
Effecten combineren op dezelfde vorm
Schaduw en 3D-opmaak kunnen naast elkaar bestaan op één vorm, waardoor gepolijste “card”-ontwerpen mogelijk zijn:
from aspose.slides_foss import (
ShapeType, FillType,
BevelPresetType, CameraPresetType, MaterialPresetType,
)
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.ROUND_CORNER_RECTANGLE, 120, 120, 360, 150
)
shape.add_text_frame("Premium Card")
# 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
tdf.bevel_top.bevel_type = BevelPresetType.CIRCLE
tdf.bevel_top.width = 8
tdf.camera.camera_type = CameraPresetType.PERSPECTIVE_ABOVE
tdf.material = MaterialPresetType.PLASTIC
# Drop shadow
ef = shape.effect_format
ef.enable_outer_shadow_effect()
ef.outer_shadow_effect.blur_radius = 14
ef.outer_shadow_effect.direction = 270
ef.outer_shadow_effect.distance = 8
ef.outer_shadow_effect.shadow_color.color = Color.from_argb(70, 0, 0, 0)
prs.save("premium-card.pptx", SaveFormat.PPTX)
