Generate dynamic image

General
1

I use Telegram a lot (but this could be any messenger or email), and instead of sending text, I would like to send an image which contains some dynamic values (multiple values, maybe different colors, font size, simple graphics, etc). I am thinking about something like the node-red-contrib-ui-svg node, but instead of showing up something in the UI, I want to save the result in a PNG file, so I can email, or send as a image message. Similar how I can do the same with node-red-contrib-chart-image which renders a chart and outputs it into a PNG file.

Does something like that exist?

You could try:

It uses Jimp for conversions and manipulations, extremely useful node.

Nice, this looks like very useful node to have. I have seen the text input options, will check if there is something similar for rudamentary graphics.
