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.
מערכת המילוי
לכל צורה יש fill_format ששולטת באופן שבו מצוירת הפנים שלה. חמשת סוגי המילוי מכסים את כל טווח פלטת העיצוב של PowerPoint.
מילוי מוצק
המילוי הפשוט ביותר, צבע אחיד עם שקיפות אופציונלית:
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)
מילוי מדרג קווי
נקודות המדרג מאפשרות לך למזג מצבע אחד לשני על פני הצורה:
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
צל מטה חיצוני
הצמד צל מטה חצי‑שקוף לכל צורה:
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)
אפקט זוהר
הילה צבעונית סביב קצה הצורה:
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
שיפוע וחומר
ה three_d_format המאפיין נותן לכל צורה שטוחה מראה תלת‑ממדי. שלבו bevel עם camera preset ו‑material לתוצאה העשירה ביותר:
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)
שילוב אפקטים על אותה צורה
הצל ועיצוב 3D יכולים להתקיים יחד על צורה אחת, מה שמאפשר עיצובים מלוטשים בסגנון “כרטיס”:
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)
התקנה
pip install aspose-slides-foss
אין צורך בהתקנת Office, אין מפתחות רישיון, אין קריאות רשת; כל העיבוד מתבצע מקומית.
