How to change output resolution
In pdf2pptx.sh I changed resolution from 1024 to 2048.
Initially I got a memory error:
convert-im6.q16: cache resources exhausted `../pres.pdf' @ error/cache.c/OpenPixelCache/4095.
...
So I changed the memory allocated in /etc/ImageMagick-6/policy.xml
Now it works, but the output presentation seems to look the same pixel-wise.
I changed the resolution to 4096 and still, it looks no clearer.
Is there something else I need to consider, perhaps with assembling the ppt file, where resolution might be lost?
I'm using WSL2.
Appreciate any help.
Altering ImageMagick policy.xml when installed using Homebrew
I am trying to follow the fix for the error (as named on the repo's homepage).
oliver$ ~/pdf2pptx/pdf2pptx.sh foo.pdf notwide
Doing foo.pdf
Removing foo.pdf.temp
convert: unable to load module '/usr/local/Cellar/imagemagick/7.0.10-29/lib/ImageMagick/modules-Q16HDRI/coders/pdf.la': file not found @ error/module.c/OpenModule/1287.
convert: no decode delegate for this image format `PDF' @ error/constitute.c/ReadImage/562.
convert: no images defined `foo.pdf.temp/slide.png' @ error/convert.c/ConvertImageCommand/3285.
Error with extraction
As can be seen, on Mac OSX my ImageMagick is/was installed using Homebrew. Trying to find the policy.xml file there appear to be two:
oliver$ find /usr/local/Cellar/imagemagick/7.0.10-29/ -name "policy.xml"
/usr/local/Cellar/imagemagick/7.0.10-29//etc/ImageMagick-7/policy.xml
/usr/local/Cellar/imagemagick/7.0.10-29//share/doc/ImageMagick-7/www/source/policy.xml
The contents of the two are largely the same (as can be seen from doing a git diff):
oliver$ git diff --no-index /usr/local/Cellar/imagemagick/7.0.10-29//share/doc/ImageMagick-7/www/source/policy.xml /usr/local/Cellar/imagemagick/7.0.10-29//etc/ImageMagick-7/policy.xml

Are you able to advise what to change to resolve the error? I have tried altering the coder policy to have rights=read, and some similar bits of tinkering, but thus far without success.
Different Aspect Ratio
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

popdPolicy.xml problems ImageMagick-7
I've tried to edit the policy XML as described in the README,
However it seems the xml file is different with ImageMagick 7.
There are a number of examples commented out, none matching the line to change as per the readme.
I copied in the desired line, but am still returning the error.
The error is present on any .pdf I try to convert, including the test.pdf included.
No such file or directory
Thank you very much for developing a useful script.
I am trying to use this script, but unfortunately, it does not work well.
It seems that the directories are not generated properly.

What if PDF size is not either 4:3 nor 16:9?
In this case, how should the shellscript be modified?
PS. Referring this document, I realized I should modify <p:sldSz> on ppt/presentation.xml.
PS 2. Actually seemed not enough....
Doesn't work on OSX, need to change sed flag
I got a bunch of errors on OSX saying "invalid command code..."
Fixed by switching -i to -i '' based on this stackoverflow post: http://stackoverflow.com/questions/7573368/in-place-edits-with-sed-on-os-x
Thanks for posting this great tool!

Conversion error even after policy.xml is changed as per README
Hi,
I have changed the policy.xml as suggested in your README. I get the following error message
pdf2pptx: line 33: 25392 Aborted (core dumped) convert -density $density
$colorspace -resize "x$ {resolution}" $1 ./$tempname/slide.png
Error with extraction
How can I workaround this issue?
JFYI, the following is the output of imagemagick version query:
