Pillow教程(二)

图片加上文字

from PIL import Image,ImageDraw,ImageFontim = Image.open('tu.jpg')draw = ImageDraw.Draw(im)(width, height) = im.sizemyfont  = ImageFont.truetype('yuanqi.ttf',size = 120)fillcolor = 'pink'#第一个参数是加入字体的坐标#第二个参数是文字内容#第三个参数是字体格式#第四个参数是字体颜色draw.text( (60,100) , u'萌萌哒' ,font = myfont , fill = fillcolor )im.save('tu_word.jpg')

图片加上数字

from PIL import Image,ImageDraw,ImageFontim = Image.open('tu.jpg')draw = ImageDraw.Draw(im)(width, height) = im.sizemyfont  = ImageFont.truetype('yuanqi.ttf',size = 120)#在图上画一个圆,ellipse参数分别为 左上角的坐标，右下角的坐标#ellipse(左上X , 左上Y , 右下X , 右下Y)draw.ellipse((width-200, 0 ,width,200),fill="red",outline="red")   draw.text((width-120,20 ),'5',font=myfont,fill='white')im.save('tu_number.jpg')

将图片转化成字符画

#coding:utf-8from PIL import Image#要索引的字符列表ascii_char = list("$@B%8&WM#*oahkbdpqwmZO0QLCJUYXzcvunxrjft/\|()1{}[]?-_+~<>i!lI;:,\"^`'. ")length = len(ascii_char) #读取图像文件def readImg():    img = Image.open('kai.png')    (width,height) = img.size    img = img.resize( ( int(width * 0.9) ,  int(height * 0.5) ))    print(img.size)    return imgdef convert(img):    # 转为灰度图像    img = img.convert('L')    txt = ''    for y in range(img.size[1]):        for x in range(img.size[0]):            # 获取每个坐标像素点的灰度            gray = img.getpixel((x,y))            unit = 256.0 / length            txt += ascii_char[(int)(gray/unit)]        txt += '\n'    return txtif __name__ == '__main__':    txt = convert(readImg())    with open('kai.txt','w') as f:        f.write(txt)
