How to Convert Pptx Files to Jpg or Png (For Each Slide) on Linux

How to convert pptx files to jpg or png (for each slide) on linux?

After Installing unoconv and LibreOffice you can use:

unoconv --export Quality=100 filename.pptx filename.pdf 

to convert your presentation to a pdf. For further options look here.

Afterwards you can - as already said above - use:

convert -density 400 my_filename.pdf -resize 2000x1500 my_filename%d.jpg 

to receive the images.

Programmatically extracting slides as images from a PowerPoint presentation (.PPT)

You should probably give unoconv a try. According to the man page, "unoconv is a command line utility that can convert any file format that OpenOffice can import, to any file format that OpenOffice is capable of exporting. "

So, to convert ppt to, say, png, you do:

unoconv -f png some-slides.ppt

Should that failed, you may try JODConverter or PyODConverter from Art of Solving. For example, you can use JODConverter from command line:

java -jar lib/jodconverter-cli-2.2.0.jar document.ppt document.png

Convert ppt/pptx to JPG/PNG using PHP on apache server

The server is an Amazon EC2 instance, so for the most part, its only CLI.

What I've done is:

I've installed Libreoffice (headless) for converting documents to PDF's using exec() in PHP.

From there I use ghostscript (already installed on the server) to extract images from the generated PDF by using exec() as well.

Convert Impress ODP Presentation to several JPG images from command line

Im going to reply my own answer.

To convert, massively, from .odp to images, under Linux using CLI, I'll do:

soffice --headless --convert-to pdf presentation.odp

Then:

convert -density 400 converted.pdf -resize 800x600 my_filename%d.jpg

This solution works, but it needs some improvements to make it faster and to prevent it from failing due to lack of hardware resources.

But, if your odp is not that big, you converted from odp/ppt/pptx/whatever to images, massively, it is scriptable, and using just CLI.

convert pptx into PNGs

It's possible on windows using comtypes library. But same cannot be said for unix distributions because comtypes isn't supported in unix. For windows,if you couldn't figure it out:

There is also python-pptx library but it doesn't have privilege for allowing to take Screenshot (Correct me if I am wrong.) In the meanwhile, this is really interesting question according to me, since there are many threads for the same, if you get it please post the answer over here.

How to convert ppt slide to jpeg images in php

I don't think thats possible. Using .NET would means that the user is creating an instance of a powerpoint application and asking it to print a specific slide to a JPG or PDF but in the case of PHP i don't think it could be possible from a linux system.

In the event you can go on windows server, then you could use the COM interface of PHP to create a COM application and start an installed PowerPoint application and do the same thing as long as the COM component is exposing the necessary methods (probably PRINT())

Good luck
