Python - PIL (Python Imaging Library)

from PIL import Image
 
orginal_image = Image.open('__porva__.png')

---

Usefull commands

orginal_image.show()
 
orginal_image.save('new_name.jpg') #can also change the format
 
size = (300, 300)
orginal_image.thumbnail(size) #scale to PIXEL size

---

IMPORTANT

Relative Path

The PIL library supports relative path: if instead of ‘file_name’ you use ‘directory1/file_name’ it will save the file, or get the file named file_name from directory1

IMPORTANT

Image Size and Numpy Array Shape

When converting an image to a numpy.array rember that width and height must be inverted:

width, height = image(size)
## ... other code
numpy_matrix = np.array(image_pixels)
numpy_matrix = numpy.matrix.reshape(height, width)

---

Convert an RPG image to Black and White

image_BW = image_RGB.convert(mode = 'L')

---

Blur the image:

blured_image = orginal_image.filter(ImageFilter.GaussianBlur(value))
