Simple exemple de code python que j'ai développé pour rendre l'arrière-fond d'une image transparent (image utilisée open-science-logo.png).
<!DOCTYPE html><html lang="en"><body style="background-color: #3c3d41;"><img src="open_science_logo.png" style="width:500px;margin: 200px 500px;"></body></html>
Code python utilisant le module PILLOW
from PIL import Imageimg = Image.open('open_science_logo.png')img = img.convert("RGBA")datas = img.getdata()newData = []for item in datas:if item[0] == 255 and item[1] == 255 and item[2] == 255:newData.append((255, 255, 255, 0))else:if item[0] > 150:newData.append((0, 0, 0, 255))else:newData.append(item)print(item)img.putdata(newData)img.save("open_science_logo_transparent.png", "PNG")
