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.

نظام المملوء

كل شكل لديه fill_format التي تتحكم في طريقة تلوين داخله. تغطي الأنواع الخمسة للملء كامل نطاق لوحة ألوان التصميم في PowerPoint.

ملء صلب

أسهل ملء، لون مسطح مع شفافية اختيارية:

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)

خطية Gradient Fill

توقف الجرادين يسمح لك لخلط من لون إلى آخر عبر الشكل:

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

الخروج من الظل

ضع ظلًا شبه شفافًا في أي شكل:

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)

تأثير Glow

حلوى ملونة حول حافة الشكل:

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

اللام والمال

ال three_d_format الخاصية تمنح أي شكل مسطح مظهرًا ثلاثي الأبعاد. اجمع بين bevel وإعداد مسبق للكاميرا وmaterial للحصول على أغنى نتيجة:

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)

تأثير مزيج على نفس الشكل

يمكن للظل والتصميم 3D أن يتزامن على شكل واحد ، مما يسمح بتصاميم “البطاقة” المقطوعة:

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)
