pycimg is a python extension for the CImg_ library.
The package contains a single class CImg that provides access to the image processing methods of the CImg_ library.
Pixel data of CImg objects can be accessed as a numpy_ array.
Vice versa new CImg objects can be created from pixel data in a numpy array or an image file. Supported file formats are png, jpeg, tiff, bmp, and cimg.
.. code-block:: python
from pycimg import CImg
import numpy as np
# Load image from file
img = CImg('test/test.png')
img.display()
# Access pixel data as numpy array
arr = img.asarray()
# Set pixels in upper left 100 x 100 px rectangle
arr[:,:,0:99,0:99] = 0
# Pixel data is shared with the image instance
img.display()
# Create image from numpy array
img = CImg(np.random.randn(100,100))Install pycimg by running:
.. code-block:: bash
pip install pycimg
