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.

Системата на пълнението

Всяка форма има една fill_format пет типа запълване покриват целия спектър на палетата за проектиране на PowerPoint.

твърдо пълнене

Най-простият начин за попълване, плосък цвят с опционална прозрачност:

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)

Линейно напълване на градиент

Градиент спира ви позволява да се смесват от един цвят към друг по формата:

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

Извън Сянка

Прикрепете полупрозрачна капка сянка към всяка форма:

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)

Ефект на Glow

Цветни хало около ръба на формата:

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

Бъдене и материал

и на three_d_format собственост дава всяка плоска форма триизмерен външен вид. Комбинирайте боклук с камера предсетка и материал за най-богатия резултат:

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)

Комбиниране на ефектите в една и съща форма

Сянка и 3D форматиране могат да съществуват заедно в една форма, което позволява полирани “карти” дизайни:

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)
