pixel-inspector

A simple pixel inspector for reading RGB or RGBA pixel values of the images.

Requirements

• Python 3.8 or above. (This piece of work was developed with Python 3.8.5).
• numpy
• matplotlib
• tkinter (, which is the standard Python interface to the Tk GUI toolkit. Hence, no need to install it.)
• Only png files are supported.

Usage

• Change to the project directory, python display.py will launch the GUI interface of this pixel inspector.
  • In the File menu, Open to load a new image for the inspection, and Exit to close the program.
  • Entry Page
  • 
  • Inspector Page
  • 
  • Notice: the position is in (x,y) where x is the horizontal direction and y is the vertical direction, and it counts from (0,0).
• Use the class PixelInspector in inspector.py to inspect the pixels with the command line.
  • For example,
  • python
  • >>>import inspector
  • >>>pi = inspector.PixelInspector('./demo/stinkbug.png')
  • >>>print(pi.inspect(300, 300))

Demo

• python
• >>>import inspector
• >>>pi = inspector.PixelInspector.demo()
