Can read photo in but not process

[Steve-Mcl]

But that is an image not a txt file? as your file node is set to read.

and there is no image-tools nodes in the flow you posted.

Maybe start again - what are you trying to do? read colour data from a specific X/Y postition?

If so, then maybe this will help...

Extract color from location on image

Assuming your image isn't a simple bitmap in a buffer (where you could calculate the offset to the pixel) you can use node-red-contrib-image-tools. If you can have the X & Y position, you can get the colour using node-red-contrib-image-tools Inject (X&Y) - image node (return image) - function node - debug Function. .. msg.image = msg.payload; var x=msg.pixel.x; var y=msg.pixel.y; msg.payload = msg.image.getPixelColor(x, y); // returns the colour of that pixel e.g. 0xFFFFFFFF return msg; EDI…
