Kako dodati slike u PowerPoint slajdove u Pythonu

Slike u Aspose.Slides FOSS su ugrađene kao picture frames, oblici koji drže sliku i mogu se postaviti, promijeniti veličinu i stilizirati poput bilo kojeg drugog oblika. Podaci slike pohranjuju se jednom u prs.images kolekciji i na njega se referencira okvir.

Preduvjeti 

pip install aspose-slides-foss

Dodaj sliku iz datoteke 

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

with slides.Presentation() as prs:
    slide = prs.slides[0]

    # Load image into the presentation's image collection
    with open("photo.jpg", "rb") as f:
        img = prs.images.add_image(f.read())

    # Add a picture frame at (x=50, y=50, width=400, height=300) in points
    frame = slide.shapes.add_picture_frame(
        ShapeType.RECTANGLE,
        50, 50, 400, 300,
        img,
    )

    prs.save("with-image.pptx", SaveFormat.PPTX)

Potpis add_picture_frame:

add_picture_frame(shape_type, x, y, width, height, image) → PictureFrame

Sve dimenzije su u pointima (1 point = 1/72 inča). Za standardni slajd od 13,33 × 7,5 inča prostor koordinata je 960 × 540 pointa.

Dodaj sliku iz bajtova

Ako već imate sliku u obliku bajtova (npr., preuzetu s URL‑a ili pročitanu iz baze podataka):

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

image_bytes = open("logo.png", "rb").read()  # or any bytes source

with slides.Presentation() as prs:
    img = prs.images.add_image(image_bytes)

    prs.slides[0].shapes.add_picture_frame(
        ShapeType.RECTANGLE,
        200, 100, 300, 200,
        img,
    )
    prs.save("logo-slide.pptx", SaveFormat.PPTX)

Upravljanje načinom popunjavanja

picture_fill_format na PictureFrame kontrolira kako se slika ispunjava granice okvira:

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

with slides.Presentation() as prs:
    img = prs.images.add_image(open("texture.png", "rb").read())
    frame = prs.slides[0].shapes.add_picture_frame(
        ShapeType.RECTANGLE, 50, 50, 600, 350, img
    )

    # STRETCH: scale image to fill the frame exactly (default)
    frame.picture_format.picture_fill_mode = PictureFillMode.STRETCH

    # TILE: repeat the image in a grid pattern
    # frame.picture_format.picture_fill_mode = PictureFillMode.TILE

    prs.save("filled.pptx", SaveFormat.PPTX)
PictureFillModePonašanje
STRETCHSkaliraj sliku da popuni okvir, zanemarujući omjer slike
TILEPonovi sliku kao pločasti uzorak
TILE_FLIPPločice s naizmjeničnim vodoravnim/okomitim okretanjem

Dodaj više slika na različite slajdove 

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

image_files = ["slide1.jpg", "slide2.jpg", "slide3.jpg"]

with slides.Presentation() as prs:
    layout = prs.slides[0].layout_slide

    # Ensure enough slides exist
    while len(prs.slides) < len(image_files):
        prs.slides.add_empty_slide(layout)

    for i, path in enumerate(image_files):
        if not os.path.exists(path):
            continue
        img = prs.images.add_image(open(path, "rb").read())
        prs.slides[i].shapes.add_picture_frame(
            ShapeType.RECTANGLE, 0, 0, 960, 540, img
        )

    prs.save("multi-image.pptx", SaveFormat.PPTX)

Broj slika u postojećoj prezentaciji 

import aspose.slides_foss as slides

with slides.Presentation("with-image.pptx") as prs:
    print(f"Presentation contains {len(prs.images)} image(s)")

Kolekcija prs.images dijeli se kroz sve slajdove: isti bajtovi slike pohranjuju se jednom, čak i ako se okvir slike pojavljuje na više slajdova.
