#图片的基本参数获取
try:
    from PIL import Image, ImageDraw, ImageFont, ImageEnhance
except ImportError:
    import Image, ImageDraw, ImageFont, ImageEnhance


img = Image.open('img.jpg')
draw = ImageDraw.Draw(img)
fontsize = min(img.size)/4
print(fontsize)
#用黑体可以写中文，如果是英文字体发现不能显示中文
myfont = ImageFont.truetype('C:/windows/fonts/simhei.ttf', size = int(fontsize))
fillcolor = "#ff0000"
width, height = img.size
draw.text((0,img.size[0]-int(fontsize)),"你好a", font=myfont, fill=fillcolor)
img.save(outputFile,'jpeg')
