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.

Fyllsystemet

Varje form har en fill_format som styr hur dess inre målas. De fem fyllningstyperna täcker hela spektrumet av PowerPoints designpalett.

Solid fyllning

Den enklaste fyllningen, en platt färg med valfri transparens:

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)

Linjär gradientfyllning

Gradientstopp gör att du kan blanda från en färg till en annan över formen:

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

Yttre kastskugga

Fäst en halvtransparent kastskugga på valfri form:

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)

Glödeffekt

En färgad halo runt formens kant:

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

Avfasning och material

Den three_d_format egenskap ger vilken plan form som helst ett tredimensionellt utseende. Kombinera en fasning med en kamerapreset och ett material för det rikaste resultatet:

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)

Kombinera effekter på samma form

Skugga och 3D-formatering kan samexistera på en enda form, vilket möjliggör polerade “kort”-designer:

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)
