Python generates random verification code

Python generates a random verification code that requires the use of the PIL module.

Installation:

PIP3 Install Pillow

Basic use

1. Create a picture

From PIL Import imageimg = image.new (mode= ' RGB ', size= (+), color= (255, 255, 255)) # Open in Picture Viewer # Img.show ()  # saved in this Ground with open (' Code.png ', ' WB ') as F:    Img.save (f,format= ' png ')

2. Create a brush to draw any content on the picture

img = image.new (mode= ' RGB ', size= (+), color= (255, 255, 255)) Draw = Imagedraw.draw (img, mode= ' RGB ')

3. Draw points

img = image.new (mode= ' RGB ', size= (+), color= (255, 255, 255)) Draw = Imagedraw.draw (img, mode= ' RGB ') # first parameter: Indicates the coordinate # second parameter Number: Denotes color draw.point ([+], fill= "Red") draw.point ([+], fill= (255, 255, 255))

4. Draw the Line

img = image.new (mode= ' RGB ', size= (+), color= (255, 255, 255)) Draw = Imagedraw.draw (img, mode= ' RGB ') # first parameter: represents the starting coordinate and the end Coordinates # SECOND parameter: Indicates the color Draw.line ((100,100,100,300), fill= ' Red ') Draw.line ((100,100,300,100), fill= (255, 255, 255))

5. Draw a Circle

img = image.new (mode= ' RGB ', size= (+), color= (255, 255, 255)) Draw = Imagedraw.draw (img, mode= ' RGB ') # first parameter: represents the starting coordinate and the end Coordinates (circle to draw in) # second argument: Represents the start angle # third parameter: Indicates end angle # Fourth parameter: Indicates color Draw.arc ((100,100,300,300), 0,90,fill= "Red")

6. Writing text

img = image.new (mode= ' RGB ', size= (+), color= (255, 255, 255)) Draw = Imagedraw.draw (img, mode= ' RGB ') # first parameter: Indicates the starting coordinate # second Parameters: Indicates write content # third parameter: Indicates color Draw.text ([0,0], ' python ', "Red")

7. Special Font text

img = image.new (mode= ' RGB ', size= (+), color= (255, 255, 255)) Draw = Imagedraw.draw (img, mode= ' RGB ') # first parameter: Indicates the font file path # Second parameter: Font size = Imagefont.truetype ("Kumo.ttf", 28) # First parameter: represents the starting coordinate # The second parameter: indicates the Write content # The third parameter: represents the color # Fourth parameter: Represents a color Draw.text ([0 , 0], ' python ', ' Red ', Font=font)

Image Verification Code

Import Random def check_code (width=120, height=30, char_length=5, font_file= ' Kumo.ttf ', font_size=28): Code = [] img = Image.new (mode= ' RGB ', size= (width, height), color= (255, 255, 255)) Draw = Imagedraw.draw (img, mode= ' RGB ') def RN Dchar (): "" "generates random letters: return:" "" Return Chr (Random.randint (+)) def Rndcolor (): "" "generates Random Color: return:" "" Return (random.randint (0, 255), Random.randint (255), RA        Ndom.randint (64, 255)) # Write Text font = Imagefont.truetype (Font_file, font_size) for I in Range (char_length): char = Rndchar () code.append (char) h = random.randint (0, 4) draw.text ([i * width/char_length, H], Char, Font=font, Fill=rndcolor ()) # Write interference point for I in range (+): Draw.point ([Random.randint (0, width), random.ra Ndint (0, height)], Fill=rndcolor ()) # Write interference circle for I in range (+): Draw.point ([Random.randint (0, width), random . randint (0, height)], fiLl=rndcolor ()) x = Random.randint (0, width) y = random.randint (0, height) draw.arc ((x, y, x + 4, y + 4), 0, Fill=rndcolor, ()) # Draw interference line for I in range (5): x1 = Random.randint (0, width) y1 = Random.randi NT (0, height) x2 = random.randint (0, width) y2 = random.randint (0, height) draw.line ((x1, y1, x2, y2 ), Fill=rndcolor ()) img = Img.filter (imagefilter.edge_enhance_more) return IMG, '. Join (code) if __name__ = = ' __mai N__ ': # 1. Directly open # Img,code = Check_code () # img.show () # 2. Write File # Img,code = Check_code () # with open (' Code.png ', ' WB ') as F: # Img.save (f,format= ' PNG ') # 3.     Write Memory (Python3) # from IO import Bytesio # stream = Bytesio () # Img.save (stream, ' png ') # Stream.getvalue () # 4.     Write Memory (Python2) # import Stringio # stream = Stringio.stringio () # Img.save (stream, ' png ') # Stream.getvalue () Pass
