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：
以上这篇Python批量生成特定尺寸图片及图画任意文字的实例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持脚本之家。
