Cara Menambah Imej ke Slaid PowerPoint dalam Python

Imej dalam Aspose.Slides FOSS disematkan sebagai picture frames, bentuk yang memegang imej dan boleh ditempatkan, diubah saiz, dan digayakan seperti mana-mana bentuk lain. Data imej disimpan sekali dalam koleksi prs.images dan dirujuk oleh bingkai.

Prasyarat

pip install aspose-slides-foss

Tambah Imej dari Fail

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)

Tandatangan add_picture_frame:

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

Semua dimensi dalam points (1 point = 1/72 inci). Untuk slaid standard 13.33 × 7.5 inci, ruang koordinat ialah 960 × 540 points.

Tambah Imej daripada Bait

Jika anda sudah mempunyai imej sebagai bait (contohnya, dimuat turun dari URL atau dibaca dari pangkalan data):

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)

Kawal Mod Isi

picture_fill_format pada PictureFrame mengawal bagaimana imej mengisi sempadan bingkai:

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)

`PictureFillMode`	Kelakuan
`STRETCH`	Skalakan imej untuk mengisi bingkai, mengabaikan nisbah aspek
`TILE`	Ulang imej sebagai corak jubin
`TILE_FLIP`	Jubin dengan pembalikan mendatar/menegak secara bergantian

Tambah Pelbagai Imej ke Slide Berbeza

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)

Kira Imej dalam Pembentangan Sedia Ada

import aspose.slides_foss as slides

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

Koleksi prs.images dikongsi merentasi semua slaid: bait imej yang sama disimpan sekali walaupun bingkai gambar muncul pada beberapa slaid.
