Different Aspect Ratio

[phelps-matthew]

Thanks for this great tool :)

I was wondering about other options for resizing. My pdf is in 16:10 aspect ratio, and using powerpoint I can convert the slides to this dimension but there is a loss in quality.

Would you be able to explain what this code snippet does?

if [ "$makeWide" = true ]; then
	pat='<p:sldSz cx=\"9144000\" cy=\"6858000\" type=\"screen4x3\"\/>'
	wscreen='<p:sldSz cy=\"6858000\" cx=\"12192000\"\/>'
	call_sed "s/${pat}/${wscreen}/g" ../presentation.xml
fi
popd

Thanks for the nice comment!
The default aspect ratio is 4:3. If the $makeWide flag is active, it would change the resolution of the final PowerPoint project to 16:9.

The code above searches for pat, the pattern for 4:3 screen, and replaces it with wscreen, the pattern for 16:9 screen, in the PowerPoint configuration file ../presentation.xml. About the numbers in the pattern, I'm not sure how exactly they correspond to the slide size, other than they have the same relative aspect ratio as the 4:3 or 16:9.

If you want to make it 16:10, I'd recommend trying this instead:

if [ "$makeWide" = true ]; then
	pat='<p:sldSz cx=\"9144000\" cy=\"6858000\" type=\"screen4x3\"\/>'
	wscreen='<p:sldSz cy=\"7620000\" cx=\"12192000\"\/>'
	call_sed "s/${pat}/${wscreen}/g" ../presentation.xml
fi

Please let me know if it works.

Yes, this worked great. As you had mentioned, I realized the ratio of cx/cy gave the right aspect but wasn't sure what to use as their absolute magnitude. The values you gave here seemed to work well. Thanks!
