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.
채우기 시스템
모든 도형은 fill_format 그 내부가 어떻게 채워지는지를 제어합니다. 다섯 가지 채우기 유형은 PowerPoint 디자인 팔레트의 전체 범위를 포괄합니다.
단색 채우기
가장 간단한 채우기로, 선택적 투명성을 가진 평면 색상입니다:
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)
선형 그라디언트 채우기
그라디언트 스톱을 사용하면 도형 전체에 걸쳐 한 색상에서 다른 색상으로 혼합할 수 있습니다:
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
외부 그림자
반투명 드롭 섀도우를 모든 도형에 적용합니다:
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)
글로우 효과
도형 가장자리 주변에 색상 광환을 추가합니다:
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
베벨 및 재질
그 three_d_format 속성은 모든 평면 도형에 3차원적인 외관을 부여합니다. 베벨을 카메라 프리셋 및 재질과 결합하면 가장 풍부한 결과를 얻을 수 있습니다:
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)
동일한 도형에 효과 결합
그림자와 3D 서식은 하나의 도형에서 동시에 사용할 수 있어 세련된 “카드” 디자인을 구현합니다:
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)
