Funkcijas un iespējas

Aspose.Slides FOSS for Python provides a broad set of capabilities for working with PowerPoint .pptx failus programmatiski. Šajā lapā ir uzskaitītas visas atbalstītās funkcionalitātes jomas ar atbilstošiem koda piemēriem.

Prezentācijas I/O

Atveriet esošu .pptx failu vai izveidojiet jaunu, pēc tam saglabājiet atpakaļ PPTX formātā.

import aspose.slides_foss as slides
from aspose.slides_foss.export import SaveFormat

# Open an existing presentation
with slides.Presentation("input.pptx") as prs:
    print(f"Slide count: {len(prs.slides)}")
    prs.save("output.pptx", SaveFormat.PPTX)

# Create a new presentation (starts with one blank slide)
with slides.Presentation() as prs:
    prs.save("new.pptx", SaveFormat.PPTX)

Piezīme: PPTX ir vienīgais atbalstītais saglabāšanas formāts. Eksportēšana uz PDF, HTML, SVG vai attēliem nav pieejama.

Nezināmi XML daļas avota failā tiek saglabātas burtiski saglabāšanas laikā, tāpēc atverot un pārsaglabājot a .pptx nekad neizņems saturu, ko bibliotēka vēl nesaprot.

Slaidu pārvaldība

Pievienojiet, noņemiet, klonējiet un pārkārtot slaidus.

import aspose.slides_foss as slides
from aspose.slides_foss.export import SaveFormat

with slides.Presentation() as prs:
    # Access the first slide
    slide = prs.slides[0]

    # Add an additional blank slide at the end
    prs.slides.add_empty_slide(prs.layout_slides[0])

    print(f"Total slides: {len(prs.slides)}")
    prs.save("multi-slide.pptx", SaveFormat.PPTX)

Formas

Pievienojiet slaidam AutoShapes, PictureFrames, tabulas un savienotājus.

AutoShapes 

import aspose.slides_foss as slides
from aspose.slides_foss import ShapeType
from aspose.slides_foss.export import SaveFormat

with slides.Presentation() as prs:
    slide = prs.slides[0]
    # Add a rectangle at (x=50, y=50) with width=300, height=100
    shape = slide.shapes.add_auto_shape(ShapeType.RECTANGLE, 50, 50, 300, 100)
    shape.add_text_frame("Aspose.Slides FOSS")
    prs.save("shapes.pptx", SaveFormat.PPTX)

Tabulas 

import aspose.slides_foss as slides
from aspose.slides_foss.export import SaveFormat

with slides.Presentation() as prs:
    slide = prs.slides[0]
    # Column widths and row heights in points
    col_widths = [120.0, 120.0, 120.0]
    row_heights = [40.0, 40.0, 40.0]
    table = slide.shapes.add_table(50, 50, col_widths, row_heights)
    table.rows[0][0].text_frame.text = "Product"
    table.rows[0][1].text_frame.text = "Quantity"
    table.rows[0][2].text_frame.text = "Price"
    prs.save("table.pptx", SaveFormat.PPTX)

Savienotāji 

import aspose.slides_foss as slides
from aspose.slides_foss import ShapeType
from aspose.slides_foss.export import SaveFormat

with slides.Presentation() as prs:
    slide = prs.slides[0]
    box1 = slide.shapes.add_auto_shape(ShapeType.RECTANGLE, 50, 100, 150, 60)
    box2 = slide.shapes.add_auto_shape(ShapeType.RECTANGLE, 350, 100, 150, 60)
    conn = slide.shapes.add_connector(ShapeType.BENT_CONNECTOR3, 0, 0, 10, 10)
    conn.start_shape_connected_to = box1
    conn.start_shape_connection_site_index = 3  # right side
    conn.end_shape_connected_to = box2
    conn.end_shape_connection_site_index = 1    # left side
    prs.save("connector.pptx", SaveFormat.PPTX)

Teksta formatēšana

Formatējiet tekstu paragrāfa un rakstzīmes līmenī, izmantojot PortionFormat.

import aspose.slides_foss as slides
from aspose.slides_foss import ShapeType, NullableBool, FillType
from aspose.slides_foss.drawing import Color
from aspose.slides_foss.export import SaveFormat

with slides.Presentation() as prs:
    slide = prs.slides[0]
    shape = slide.shapes.add_auto_shape(ShapeType.RECTANGLE, 50, 50, 500, 150)
    tf = shape.add_text_frame("Bold blue heading")

    fmt = tf.paragraphs[0].portions[0].portion_format
    fmt.font_height = 28
    fmt.font_bold = NullableBool.TRUE
    fmt.fill_format.fill_type = FillType.SOLID
    fmt.fill_format.solid_fill_color.color = Color.from_argb(255, 0, 70, 127)

    prs.save("text.pptx", SaveFormat.PPTX)

NullableBool.TRUE iestata īpašību tieši; NullableBool.NOT_DEFINED manto no slaidu galvenā.

Aizpildījuma veidi

Lietojiet vienkāršu, gradienta, rakstu vai attēla aizpildījumus formām.

import aspose.slides_foss as slides
from aspose.slides_foss import ShapeType, FillType
from aspose.slides_foss.drawing import Color
from aspose.slides_foss.export import SaveFormat

with slides.Presentation() as prs:
    slide = prs.slides[0]
    shape = slide.shapes.add_auto_shape(ShapeType.RECTANGLE, 50, 50, 300, 150)

    # Solid fill
    shape.fill_format.fill_type = FillType.SOLID
    shape.fill_format.solid_fill_color.color = Color.from_argb(255, 30, 120, 200)

    prs.save("fill.pptx", SaveFormat.PPTX)

Vizuālie efekti

Lietojiet ārējo ēnu, spīdumu, mīkstu malu, izpludināšanu, atspoguļojumu un iekšējo ēnu formām.

Efekta īpašības ir pieejamas caur shape.effect_format. Iestatīt outer_shadow_effect, glow_effect, soft_edge_effect, blur_effect, reflection_effect, vai inner_shadow_effect lai konfigurētu katru neatkarīgi.

3D Formatting

Lietojiet 3D slīpumu, kameru, apgaismojuma rigu, materiālu un izspiešanas dziļumu caur shape.three_d_format. Tas kontrolē vizuālo dziļumu un apgaismojuma modeli figūru attēlošanai PPTX skatītājos, kas atbalsta 3D efektus.

Runātāja piezīmes

Pievienojiet piezīmes jebkuram slaidam, izmantojot notes_slide_manager.

import aspose.slides_foss as slides
from aspose.slides_foss.export import SaveFormat

with slides.Presentation() as prs:
    notes = prs.slides[0].notes_slide_manager.add_notes_slide()
    notes.notes_text_frame.text = "Key talking point: emphasize the ROI benefit."
    prs.save("notes.pptx", SaveFormat.PPTX)

Komentāri

Pievienojiet pavedienveida komentārus ar autora informāciju un slaida pozīciju.

import aspose.slides_foss as slides
from aspose.slides_foss.drawing import PointF
from aspose.slides_foss.export import SaveFormat

    slide = prs.slides[0]
    author.comments.add_comment(
        "Please verify this data before the presentation.",
        slide,
        PointF(2.0, 2.0),
        datetime.now()
    )
    prs.save("comments.pptx", SaveFormat.PPTX)

with slides.Presentation() as prs:
    with open("logo.png", "rb") as f:
        image_data = f.read()
    image = prs.images.add_image(image_data)
    slide = prs.slides[0]
    slide.shapes.add_picture_frame(
        slides.ShapeType.RECTANGLE, 50, 50, 200, 150, image
    )
    prs.save("with-image.pptx", SaveFormat.PPTX)
