给图片加文字，网上有很多，下面我不想在图片里面加文字，而是把文字加在图片上面当做标题，这样的做法可以不破坏原来的图片，另外还加了一个方法，除了加文字，还可以随意拼接图片，需要使用到pillow库

安装pillow：pip install pillow 卸载pillow：pip uninstall pillow 豆瓣的下载比较快：pip install -i https://pypi.douban.com/simple pillo

from PIL import Image from PIL import ImageFilter from PIL import ImageEnhance from PIL import ImageDraw,ImageFont #图片宽高尺寸 def getImgSize(fname): imgObj=Image.open(fname) return imgObj.size #获取图片宽度 def getImgWidth(fname): imgObj=Image.open(fname) return imgObj.size[0] #获取图片高度 def getImgHeight(fname): imgObj=Image.open(fname) return imgObj.size[1] ''' 给图片加文字生成一张blankimg空白图片，加上文字之后为fontimg图片,宽度为oldimg原始图片的宽度 ''' def imgAddFont(blankimg,oldimg,fontimg): Image.new("RGB" ,(getImgWidth(oldimg),70),(255,255,255)).save(blankimg,"PNG"); im = Image.open(blankimg) draw = ImageDraw.Draw(im) fnt = ImageFont.truetype(r'C:\Windows\Fonts\simsun.ttc',22) draw.text((50, 20), '新鲜的水果，0元包邮出售！\n仅限三天，赶快订购，领取购物券进行购买即可！！！', fill='red', font=fnt) im.show() im.save(fontimg) imgAddFont('imgs/blank.png','imgs/1.jpg','newImgs/font.jpg') ''' 拼接图片，把上面生成的文字图片拼接到原图上面生成一张宽度一致，高度为两张图片之和的空白长图分别打开图片进行粘贴到空白长图里面 ''' def joinImg(fontimg,oldimg,newimg): w=getImgWidth(fontimg) fh=getImgHeight(fontimg) oh=getImgHeight(oldimg) blankLongImg=Image.new('RGBA',(w,fh+oh))#空白长图 fontimg1=Image.open(fontimg).resize((w, fh),Image.ANTIALIAS) blankLongImg.paste(fontimg1,(0,0)) oldimg1=Image.open(oldimg).resize((w, oh),Image.ANTIALIAS) blankLongImg.paste(oldimg1,(0,fh)) blankLongImg.save(newimg) print('新拼接的图片：'+newimg) joinImg('newImgs/font.jpg','imgs/1.jpg','newImgs/new.png') ''' 拼接上下两张图片 ''' def joinTwoImg(fontimg,topimg,bottomimg,newimg): w=getImgWidth(fontimg) fh=getImgHeight(fontimg) th=getImgHeight(topimg) bh=getImgHeight(bottomimg) blankLongImg=Image.new('RGBA',(w,fh+th+bh))#空白长图 fontimg1=Image.open(fontimg).resize((w, fh),Image.ANTIALIAS) blankLongImg.paste(fontimg1,(0,0)) topimg1=Image.open(topimg).resize((w, th),Image.ANTIALIAS) blankLongImg.paste(topimg1,(0,fh)) bottomimg1=Image.open(bottomimg).resize((w, bh),Image.ANTIALIAS) blankLongImg.paste(bottomimg1,(0,fh+th)) blankLongImg.save(newimg) print('新拼接的图片：'+newimg) joinTwoImg('newImgs/font.jpg','imgs/1.jpg','imgs/2.jpg','newImgs/new.png')
