Convert PPTM Slides to PNG Images in Python

Convert PPTM to PNG in Python

Aspose.Slides for Python via Java can render the slides in a macro-enabled PowerPoint presentation (.pptm) as PNG images without Microsoft PowerPoint. Because one PNG file stores one image, the conversion creates a separate output file for each slide. Animations, transitions, macros, and other interactive behavior are not included in the rendered images.

Access each slide through a variable, call getImage, and save the returned image with ImageFormat.Png. The scaling values passed to getImage control the output dimensions relative to the original slide size.

Convert PPTM to PNG using Python

Load the PPTM file into a Presentation, render each slide with getImage, and save each result in PNG format.

presentation = Presentation("presentation.pptm")
try:
    slide_count = presentation.getSlides().size()

    for slide_index in range(slide_count):
        slide = presentation.getSlides().get_Item(slide_index)
        slide_image = slide.getImage(2.0, 2.0)
        try:
            file_path = f"slide-{slide_index + 1}.png"
            slide_image.save(file_path, ImageFormat.Png)
        finally:
            slide_image.dispose()
finally:
    presentation.dispose()
