Using Jimp in function node

[Steve-Mcl]

I wanted to use Jimp (which is installed with node-red-contrib-image-tools) inside function node. My usage is to get pixel array out of png image

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
