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

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：
