Pillow 使用PostScript打印

Python图像库包含在PostScript打印机上打印图像、文本和图形的函数。下面是一个简单的例子:

绘图后记

from PIL import Image
from PIL import PSDraw

with Image.open("hopper.ppm") as im:
    title = "hopper"
    box = (1*72, 2*72, 7*72, 10*72) # in points

    ps = PSDraw.PSDraw() # default is sys.stdout
    ps.begin_document(title)

    # draw the image (75 dpi)
    ps.image(box, im, 75)
    ps.rectangle(box)

    # draw title
    ps.setfont("HelveticaNarrow-Bold", 36)
    ps.text((3*72, 4*72), title)

    ps.end_document()
