Overlay text onto image

General
1

I've been unable to find any examples online of how to overlay text onto an image. I'm using a http request node to return a binary buffer from an IP camera. Then I'm formatting the date/time (contrib-moment), setting the filename with a function node and saving the image to a file. Everything works up to this point except I have no idea how to overlay text (context variable) onto the image. Using contrib-image-output for image preview in the flow.

Forgot to mention, once installed, there is a demo flow in the importable examples that does just this.

Thanks, looks like that should do it.

Very powerful image toolset, is there any plans on TIFF support? Thanks

You can load & modify and save TIFFs already.

There is an issue with the built in viewer (for viewing inside the node-red editor )- otherwise, everything else works.

EIDT: multi image TIFFs will either not work or you will get 1st image (haven't tested)
