Convert .png images into a .ppt presentation on Linux?

Question

I've created a presentation as a series of .png images, one per slide. What is a good way to convert these into a .ppt (PowerPoint) that I can give to some audio-visual person? I'm entirely on Linux, with no Windows or Mac software available.

(Or maybe PowerPoint isn't the only game in town for presentation file formats?)

Solution 1

I'd output to PDF, which is commonly used for presentations. To convert use the convert program (from Image Magick).

convert *.png presentation.pdf

If you don't have convert yet, install the imagemagick package

sudo apt-get install imagemagick

(It looks like you can also use convert directly to a .ppt file, but for me this doesn't work as well.)

Solution 2

You can use OpenOffice.org Impress to import each of these PNGs into single slide, apply the desired transitions and export to a .ppt file.

OpenOffice.org comes with most Linux distros

Solution 3

Rather than try to directly convert the PNG files to a PDF or other format presentation, create a new presentation in Inkscape with the PNGs imported. Inkscape with Inkscape Slides turns out to be a great way to make presentations, and a good way to deal with old presentations that exist only as PNGs. (See question Converting Inkscape layers directly to a slideshow presentation?)

However, the other answer recommending ImageMagick convert is useful too.

Well, that seems obvious! Will try that. I did try OO a while ago, but thinking only of using Impress to create the content. I found it lacking in graphics capability.

This has the disadvantage of having to manually deal with each image. Is there a way to handle say 50 images at once?

Looks good and easy. Will try that. I wonder if ImageMagick can go the opposite way - make .png or .jpg from a given .pdf?

I use pdfimages for that. It extracts all the embedded images from a pdf (part of xpdf-utils package).

I'm not sure. Have a look at @Dennis' answer superuser.com/questions/132767/…
