Get pixel details

[kirkstrobeck]

How would you go about getting the color of a specific XY coord of a pixel?

Yes i too am considering using gm in our production servers. However a part of the problem requires to read specific pixels (bordering pixels) to consider if the image needs trimming at all.

+1. Need to trim borders from images. Trying to figure out how.

Just noticed there's a trim method. gonna try that one. Have you tried it?

Any solution to this? :thought_balloon:

I managed to get the pixel data using this method:

img.out('-crop').out('1x1+25+30').out('-depth').out('8');
img.toBuffer('txt', (err, buffer) => {
   console.log(buffer.toString());
}

This seems to be rather slow but since I only need to check couple of pixels it's fine for my use case. A nicer and faster way of doing this would be great.
