Run a timer when a functions starts to see how long the function takes to complete - Pedroski55 - Apr-19-2020 I made a little Python to remove watermarks from pdfs. It works OK. After splitting the pdf into jpgs, I look for grey pixels and paint them white. I just changed it to take the lowest grey range as a variable. The smaller the variable lowestGrey = int(Grey), and of course, the greater the number of pixels, the longer the function takes to complete. Also, it's a trade-off: the Chinese characters in the pdf contain grey pixels too. If lowestGrey is too small, the characters get very scruffy. Just out of interest, I'd like to time the function. How can I set a timer? The timer should start when the function is called and print its result when the function is done. def removeWM(path, aJPG, grey): picture = Image.open(path + aJPG) saveas = aJPG.split('.') savename = saveas[0] + 'WMgone.jpg' width, height = picture.size for x in range(0, width): for y in range(0, height): r,g,b = picture.getpixel( (x,y) ) if r and g and b in range(grey, 253): picture.putpixel( (x,y), (255, 255, 255)) # white is 3 x 255 picture.save(pathToWMgone + savename) print(aJPG + ' watermark gone and saved') RE: Run a timer when a functions starts to see how long the function takes to complete - michael1789 - Apr-19-2020 You could use the built-in time() module. import time start = time.time() #put this as the first line of the function end = time.time() #put this at the end of the function print(end - start)That said, if your intention is to steal artwork, I encourage you to try making some or use the literally billions of free images that exist. RE: Run a timer when a functions starts to see how long the function takes to complete - Pedroski55 - Apr-19-2020 Thanks a lot! No, no stealing here! These are old exams, watermarked by various education agencies, to whom they do not belong. They are rightly the property of the university that created them. The gf asked me to get rid of the watermark and then watermark them for the agency she works for. Definitely not art. Worked great! Result: Quote:Now getting the jpgs to remove the wm ... |
