ImageMagick, Can ImageMagick return single annotation as a bitmap?

will help you If you just want the annotation and no background, you presumably need a transparent background so you can later overlay the annotation on another image. In that case, you need to store it in a format that supports transparency, such as PNG, so use:
code :
convert -background transparent -pointsize  32 -fill blue label:"I am on a transparent background" text.png

around this issue node-imagemagick actually calls the CLI tools (using child_process), hence the dependency.
As for an alternative, it really depends on what type of image manipulation you need (and also their dependencies as well, given that it has to run in a Paas platform). There's a nice list of graphics modules on the Node wiki.

wish of those help I see the same problem with your sample file. It looks like ImageMagick's delegates for the PDF conversion may have changed with the new install.
If you try convert -verbose foo.pdf foo.jpeg, do you see -sDEVICE=pngalpha in the command that gets sent to gs? The pnmraw device has been used in the past, and switching back to that seems to fix the problem for me.

it should still fix some issue I finally found the solution. Instead of doing gem uninstall rmagick try using bundle exec gem uninstall rmagick.
I hope it will help someone else!

help you fix your problem Your best chance to achieve that is to share the portable version of ImageMagick. Look up ImageMagick portable on Google, download the files and put them on a share.
