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 Isian
Setiap bentuk memiliki sebuah fill_format yang mengontrol bagaimana interiornya diwarnai. Lima jenis isian mencakup seluruh rentang palet desain PowerPoint.
Isian Solid
Isian 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)
Isian Gradien Linear
Titik henti gradien memungkinkan Anda mencampur satu warna ke warna 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 Jatuh Luar
Lampirkan bayangan jatuh semi-transparan pada bentuk apa pun:
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 Cahaya
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 Material
Properti three_d_format memberikan tampilan tiga dimensi pada setiap bentuk datar. Gabungkan bevel dengan preset kamera dan material untuk hasil 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 berdampingan pada satu bentuk, memungkinkan desain “kartu” yang halus:
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)
