Gist Clients

Want to create a Gist from your editor, the command line, or the Services menu? Here's how.

Editor Support

ppt2vbs

export a Powerpoint presentation to JPEG images, one per slide. Used as a workaround to the broken JPEG export in Powerpoint itself, which yields only low quality images.

Usage

You can adjust the image resolution by varying the numerical argument in line 46, in the call to ExportSlides.

Just drag and drop one or more PPT or PPTX files onto the vbs script. The script will process each, showing a short message, and

written in notepad.exe and completely untested - Python has never seen this code :-)

I use Windows, MINGW64 bash, Python 3.5.2. In an empty directory:

$ virtualenv ENV
[...]
$ source ENV/Scripts/activate
(ENV) $ pip install ablog
[...]
(ENV) $ pip show ablog
Name: ablog
