Multiple extensions handler with Image Magick

[Cicorione]

Hi Patrick,

I can't find a way to work with multiple extensions handler, this doesn't work:

imagehandler=jpegimage:(/usr/bin/convert %%input%% -resize 50% -strip -resample 72 -colorspace Gray %%output%%)
extensionhandler="jpg:jpegimage"
imagehandler=pngimage:(/usr/bin/convert %%input%% -resize 50% -strip -resample 72 -colorspace Gray %%output%%)
extensionhandler="png:pngimage"
imagehandler=pdfimage:(/usr/bin/convert %%input%% -resize 50% -strip -resample 72 -colorspace Gray %%output%%)
extensionhandler="pdf:pdfimage"

Nor:

extensionhandler="pdf:pdfimage;png:pngimage;jpg:jpegimage"

or

extensionhandler="pdf:pdfimage";"png:pngimage";"jpg:jpegimage"

What is it the correct syntax?

Thanks... 🙏

The documentation says:

extensionhandler="mmd:mermaid". Multiple entries are separated by semicolon. See also imagehandler. (Since version 3.9.1.)

I bet I made a pebcak... 🤦‍♂️

I got this...

extensionhandler="jpg:jpegimage;png:pngimage;pdf:pdfimage"
imagehandler=jpegimage:(convert %%input%% -resize 50% -strip -resample 72 -colorspace Gray %%output%%);pngimage:(convert %%input%% -resize 50% -strip -resample 72 -colorspace Gray %%output%%);pdfimage:(convert %%input%% -resize 50% -strip -resample 72 -colorspace Gray %%output%%)

I will extend the manual.
