下面的代码展示了如何通过创建绘图对象在图像上写入文本
from PIL import Image, ImageFont, ImageDraw
image = Image.new(mode = "RGBA" , size= (500, 508) )
draw = ImageDraw.Draw(image)
font = ImageFont.load("arial.pil")
draw.text((10, 10), "hello", font=font)
我要求的是如何将文本作为枕头对象返回，这样我就可以将其粘贴到另一个图像上，而不必创建图像对象并绘制对象，然后在其上写入文本，我只想将原始文本作为枕头对象稍后在 .paste() 函数中使用它。 类似的东西（代码不存在，但这是我可以想象的）：
from PIL import Image, ImageFont, ImageDraw
image = Image.new(mode = "RGBA" , size= (500, 508) )
font = ImageFont.load("arial.pil")
text = font.loadtext("hello") #imaginary part (a pillow object)
image.paste(text, (10,10))
您可以创建一个函数来创建一块空画布并绘制文本并将其作为PIL Image像这样：
#!/usr/local/bin/python3
from PIL import Image, ImageFont, ImageDraw, ImageColor
def GenerateText(size, fontname, fontsize, bg, fg, text, position):
"""Generate a piece of canvas and draw text on it"""
canvas = Image.new('RGBA', size, bg)
# Get a drawing context
draw = ImageDraw.Draw(canvas)
font = ImageFont.truetype(fontname, fontsize)
draw.text(position, text, fg, font=font)
return canvas
# Create empty yellow image
im = Image.new('RGB',(400,100),'yellow')
# Generate two text overlays - a transparent one and a blue background one
w, h = 200, 100
transparent = (0,0,0,0)
textoverlay1 = GenerateText((w,h), 'Arial', 16, transparent, 'magenta', "Magenta/transparent", (20,20))
textoverlay2 = GenerateText((w,h), 'Apple Chancery', 20, 'blue', 'black', "Black/blue", (20,20))
# Paste overlay with transparent background on left, and blue one on right
im.paste(textoverlay1, mask=textoverlay1)
im.paste(textoverlay2, (200,0), mask=textoverlay2)
# Save result
im.save('result.png')
这是粘贴前的初始黄色图像：
这是粘贴两个叠加层后的结果：
