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 za punjenje

Svaki oblik ima svoj… fill_format Pet vrsta ispunjenja pokriva cijeli raspon PowerPointove palete dizajna.

Čvrsto punjenje

Najlakše ispunjenje, ravna boja s opcionalnom transparentnošću:

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)

Izvršenje linearnog gradijenta

Gradientni zaustavci omogućuju vam da se pomiješate iz jedne boje u drugu preko oblika:

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

Izvanjski senka za padavine

Ustavite poluprozirnu sjenku za kap na bilo koji oblik:

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)

Efekat svjetlosti

Boja halo oko ruba oblika:

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

Zidovi i materijal

U skladu s člankom 1. three_d_format Kombinacija bezla s kamera preset i materijal za najbogatiji rezultat:

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)

Kombinacija učinaka na isti oblik

Sjenka i 3D formatiranje mogu koegzistirati na jednom obliku, omogućavajući polirane “kart” dizajne:

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)
