Get RGB info of one pixel

[marciano]

Is it possible to get RGB values of the top left pixel of a jpg photo?

[marciano]

Pixel position (n,m).
Image Magick Linux command line:

Code Select Expand

convert photo.jpg[1x1+n+m] -format "%[fx:int(255*r)],%[fx:int(255*g)],%[fx:int(255*b)]" info:
Output: red value, green value, blue value

Glad you found a solution.

Exiftool would not be a solution here. Exiftool only deals with metadata. It has no ability to read image data.
