Python批量生成特定尺寸图片及图画任意文字的实例

因为工作需要生成各种大小的图片，所以写了个小脚本，顺便支持了下图画文字内容。

具体代码如下：

from pil import image, imagedraw, imagefont
'''
  auth: xiaowu chen
  note: please install [pillow] library before run this script.
'''
 
 
def draw_image(new_img, text, show_image=false):
  text = str(text)
  draw = imagedraw.draw(new_img)
  img_size = new_img.size
  draw.line((0, 0) + img_size, fill=128)
  draw.line((0, img_size[1], img_size[0], 0), fill=128)
 
  font_size = 40
  fnt = imagefont.truetype('arial.ttf', font_size)
  fnt_size = fnt.getsize(text)
  while fnt_size[0] > img_size[0] or fnt_size[0] > img_size[0]:
    font_size -= 5
    fnt = imagefont.truetype('arial.ttf', font_size)
    fnt_size = fnt.getsize(text)
 
  x = (img_size[0] - fnt_size[0]) / 2
  y = (img_size[1] - fnt_size[1]) / 2
  draw.text((x, y), text, font=fnt, fill=(255, 0, 0))
 
  if show_image:
    new_img.show()
  del draw
 
 
def new_image(width, height, text='default', color=(100, 100, 100, 255), show_image=false):
  new_img = image.new('rgba', (int(width), int(height)), color)
  draw_image(new_img, text, show_image)
  new_img.save(r'%s_%s_%s.png' % (width, height, text))
  del new_img
 
 
def new_image_with_file(fn):
  with open(fn, encoding='utf-8') as f:
    for l in f:
      l = l.strip()
      if l:
        ls = l.split(',')
        if '#' == l[0] or len(ls) < 2:
          continue
 
        new_image(*ls)
 
 
if '__main__' == __name__:
  new_image(400, 300, 'hello world any size', show_image=true)
  # new_image_with_file('image_data.txt')
 
 

如果你需要批量的话，批量数据文件的格式如下：

#width,height,text
200,200,hello
300,255,world

执行后的效果如下：
