Q1：如何用 PIL / Pillow 將 Python 的文字輸出從螢幕轉向到圖形檔？

A1：參考代碼一 [3], [4]。

PIL / Pillow 雖有強大易用的影像處理功能 [1], [2]，但此處只簡單使用其文字轉影像的部分 [3]，另外請自行下載字型檔 [4]。

代碼一

# 代碼一

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

f_p = '/content/drive/My Drive/colab/data/titanic/' # file path
font = ImageFont.truetype(f_p+'Ubuntu-Regular.ttf', 50)

img1 = Image.open(f_p+'t0005_3.png')
img2 = Image.open(f_p+'t0005_3.png')
img3 = Image.open(f_p+'t0005_3.png')

draw1 = ImageDraw.Draw(img1)
draw1.text((900, 50), "dtype", (255, 255, 255), font=font)
img1.save(f_p+'t0006_1.png')

draw2 = ImageDraw.Draw(img2)
draw2.text((900, 50), "object", (255, 255, 255), font=font)
img2.save(f_p+'t0006_2.png')

draw3 = ImageDraw.Draw(img3)
draw3.text((900, 50), "non-null", (255, 255, 255), font=font)
img3.save(f_p+'t0006_3.png')
