PIL - 在图像上绘制多行文本 [英] PIL - draw multiline text on image

问题描述

我尝试在图像底部添加文本，实际上我已经完成了，但是如果我的文本比图像宽度长，则从两侧剪掉它，以简化我希望文本在多行中如果它长于图像宽度.这是我的代码:

I try to add text at the bottom of image and actually I've done it, but in case of my text is longer then image width it is cut from both sides, to simplify I would like text to be in multiple lines if it is longer than image width. Here is my code:

FOREGROUND = (255, 255, 255)
WIDTH = 375
HEIGHT = 50
TEXT = 'Chyba najwyższy czas zadać to pytanie na śniadanie 
 Chyba najwyższy czas zadać to pytanie na śniadanie'
font_path = '/Library/Fonts/Arial.ttf'
font = ImageFont.truetype(font_path, 14, encoding='unic')
text = TEXT.decode('utf-8')
(width, height) = font.getsize(text)

x = Image.open('media/converty/image.png')
y = ImageOps.expand(x,border=2,fill='white')
y = ImageOps.expand(y,border=30,fill='black')

w, h = y.size
bg = Image.new('RGBA', (w, 1000), "#000000")

W, H = bg.size
xo, yo = (W-w)/2, (H-h)/2
bg.paste(y, (xo, 0, xo+w, h))
draw = ImageDraw.Draw(bg)
draw.text(((w - width)/2, w), text, font=font, fill=FOREGROUND)


bg.show()
bg.save('media/converty/test.png')

推荐答案

你可以使用 textwrap.wrap 将 text 分解成一个字符串列表，每个字符串最多 width 个字符长:

You could use textwrap.wrap to break text into a list of strings, each at most width characters long:

import textwrap
lines = textwrap.wrap(text, width=40)
y_text = h
for line in lines:
    width, height = font.getsize(line)
    draw.text(((w - width) / 2, y_text), line, font=font, fill=FOREGROUND)
    y_text += height
