通過使用python pil，我想使圖像居中，並包含來自url的文本並下載。 怎么做？

Question

我在url中輸入了文本，並希望獲得文本居中的下載圖像。

例如，當我輸入http://127.0.0.1:8000/app/hello時 ，便會下載圖像。 該圖像使文本“ hello”居中

def homework(request, name):
text = name
img = Image.new('RGB',(256,256),(0,0,0))
draw = ImageDraw.Draw(img)

font = ImageFont.load_default().font
draw.text((128,128), text, font = font, fill="black")

with open(img, 'rb') as f:
    response = HttpResponse(f, content_type='image/jpeg')
    response['Content-Disposition'] = 'attachment; filename="textimage"'
    return response

通過使用python pil。

怎么做？

#install PIL (Pillow) via Pip

from PIL import Image
from PIL import ImageFont
from PIL import ImageDraw 

#position of Text
x = 50
y = 50

#font color as tuple
color = (255, 255, 255)

#download the image to the local system and open it
img = Image.open("1.jpg")

#draw image and prepare font
draw = ImageDraw.Draw(img)
font = ImageFont.truetype('arial.ttf', size=30)

#draw text on image
draw.text((x, y),"Sample Text", color,font=font)

#save the new image, that contains the text
img.save('sample-out.jpg')
