Hi,

I would be grateful if some help me to solve the issue.
Ubuntu - 18.04
Node - v8.10.0
image-watermark - 0.0.7

I am getting the issue when I try to add watermark on the pdf file.
I have installed ImageMagick.

/home/gowtham/Desktop/node/node_modules/image-watermark/watermark.js:196
                throw new Error('Image-Watermark::embedWatermark : Unable to process image file : ' + err);
                ^

Error: Image-Watermark::embedWatermark : Unable to process image file : Error: Command failed: identify-im6.q16: not authorized `sample.pdf' @ error/constitute.c/ReadImage/412.

You have to install GhostScript. I faced the same problem and got an answer from stackoverflow from here.

Can you please share the code to guide how to use GhostScript

@prafulrajhm You don't have to use anything, just install ghost-script on your system.
