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.
Sistem Pengisian
Setiap bentuk memiliki … fill_format Lima jenis isi mencakup seluruh palet desain PowerPoint.
Isian padat
Pengisian paling sederhana, warna datar dengan transparansi opsional:
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)
Penuh Linier Gradien
Stop gradien memungkinkan Anda untuk berbaur dari satu warna ke yang lain di seluruh bentuk:
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
Bayangan Drop Luar
Pasanglah drop shadow semi-transparan pada bentuk apapun:
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)
Efek Terang
Sebuah halo berwarna di sekitar tepi bentuk:
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 dan Bahan
Pengelolaan three_d_format Kombinasi bevel dengan preset kamera dan bahan untuk hasil yang paling kaya:
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)
Menggabungkan Efek pada Bentuk yang Sama
Bayangan dan pemformatan 3D dapat hidup bersama pada satu bentuk, memungkinkan desain “kartu” yang dipoles:
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)
