Working with Images in Presentations — Aspose.Slides FOSS for Python

Aspose.Slides FOSS for Python lets you embed images in a presentation’s shared image collection and display them on slides using PictureFrame shapes. Images can also be used as shape background fills via FillType.PICTURE.

Adding an Image from File

Load image bytes from disk and add them to the presentation’s image collection with prs.images.add_image(). Then place the image on a slide as a PictureFrame:

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

with slides.Presentation() as prs:
    # Add the image to the shared collection
    with open("logo.png", "rb") as f:
        img = prs.images.add_image(f.read())

    # Place it on the slide as a PictureFrame
    slide = prs.slides[0]
    slide.shapes.add_picture_frame(ShapeType.RECTANGLE, 50, 50, 300, 200, img)

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

The four positional arguments to add_picture_frame() are: x, y, width, height in points.

Adding an Image from Bytes

If you already have image bytes (e.g., downloaded from a URL or read from a database), pass them directly to add_image():

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

# Simulate having bytes in memory
with open("photo.jpg", "rb") as f:
    image_bytes = f.read()

with slides.Presentation() as prs:
    img = prs.images.add_image(image_bytes)
    prs.slides[0].shapes.add_picture_frame(ShapeType.RECTANGLE, 100, 80, 400, 250, img)
    prs.save("from-bytes.pptx", SaveFormat.PPTX)

Positioning and Sizing a PictureFrame

The PictureFrame returned by add_picture_frame() inherits all Shape geometry properties and can be repositioned after creation:

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

with slides.Presentation() as prs:
    with open("photo.jpg", "rb") as f:
        img = prs.images.add_image(f.read())

    pf = prs.slides[0].shapes.add_picture_frame(ShapeType.RECTANGLE, 0, 0, 100, 100, img)

    # Reposition and resize after creation
    pf.x = 50
    pf.y = 100
    pf.width = 350
    pf.height = 250

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

Using an Image as a Shape Fill

Any shape (not just PictureFrame) can use an image as its background fill. Set fill_type = FillType.PICTURE and assign the image to picture_fill_format.picture.image:

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

with slides.Presentation() as prs:
    with open("background.png", "rb") as f:
        img = prs.images.add_image(f.read())

    slide = prs.slides[0]
    shape = slide.shapes.add_auto_shape(ShapeType.ROUNDED_RECTANGLE, 50, 50, 400, 250)
    shape.fill_format.fill_type = FillType.PICTURE
    shape.fill_format.picture_fill_format.picture_fill_mode = PictureFillMode.STRETCH
    shape.fill_format.picture_fill_format.picture.image = img

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

PictureFillMode.STRETCH scales the image to fill the entire shape. Use TILE or TILE_FLIP for repeating patterns.

Adding Multiple Images Across Slides

Images added to prs.images are shared across all slides. The same Image object can be used on multiple slides without duplicating the data:

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

with slides.Presentation() as prs:
    with open("logo.png", "rb") as f:
        logo = prs.images.add_image(f.read())

    # Add the same image to both slides
    prs.slides[0].shapes.add_picture_frame(ShapeType.RECTANGLE, 600, 10, 100, 40, logo)

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