There is no need to import Jimp.

What you are doing here is (unnecessarily) importing a DIFFERENT version of Jimp to the version image-tools installs.

The image node already outputs the image (and its properties) so you can access the pixel data see this example where I set `msg.image` in the image node and in the function "colorise" I call `setPixelColor`: [How to generate an image from the 8x8 raw heat map data of an AMG8833 thermal sensor - #8 by Steve-Mcl](https://discourse.nodered.org/t/how-to-generate-an-image-from-the-8x8-raw-heat-map-data-of-an-amg8833-thermal-sensor/31604/8)
