我一直在使用PIL图片
我正在尝试在图像上绘制文本。我希望此文字像大多数模因一样具有黑色轮廓。我试图通过在前面的字母后面绘制较大字体的阴影字母来实现此目的。我已经相应地调整了阴影的x和y位置。阴影虽然略微掉了。前面的字母应恰好在阴影字母的中间,但事实并非如此。问号当然不是水平居中,所有字母垂直都太低。轮廓也不太好。
下面是产生上面图像的最小可复制示例。
from PIL import Image, ImageDraw, ImageFont
caption = "Why is the text slightly off?"
img = Image.open('./example-img.jpg')
d = ImageDraw.Draw(img)
x, y = 10, 400
font = ImageFont.truetype(font='./impact.ttf', size=50)
shadowFont = ImageFont.truetype(font='./impact.ttf', size=60)
for idx in range(0, len(caption)):
char = caption[idx]
w, h = font.getsize(char)
sw, sh = shadowFont.getsize(char) # shadow width, shadow height
sx = x - ((sw - w) / 2) # Shadow x
sy = y - ((sh - h) / 2) # Shadow y
# print(x,y,sx,sy,w,h,sw,sh)
d.text((sx, sy), char, fill="black", font=shadowFont) # Drawing the text
d.text((x, y), char, fill=(255,255,255), font=font) # Drawing the text
x += w + 5
img.save('example-output.jpg')
Another approach包括在主文本后面的稍高,稍低,稍左和稍右的位置上用黑色绘制了四次黑色文本,但是这些效果也不是最佳选择,如下所示:
产生上面图像的代码
from PIL import Image, ImageDraw, ImageFont
caption = "Why does the Y and i look weird?"
x, y = 10, 400
font = ImageFont.truetype(font='./impact.ttf', size=60)
img = Image.open('./example-img.jpg')
d = ImageDraw.Draw(img)
shadowColor = (0, 0, 0)
thickness = 4
d.text((x - thickness, y - thickness), caption, font=font, fill=shadowColor, thick=thickness)
d.text((x + thickness, y - thickness), caption, font=font, fill=shadowColor, thick=thickness)
d.text((x - thickness, y + thickness), caption, font=font, fill=shadowColor, thick=thickness)
d.text((x + thickness, y + thickness), caption, font=font, fill=shadowColor, thick=thickness)
d.text((x, y), caption, spacing=4, fill=(255, 255, 255), font=font) # Drawing the text
img.save('example-output.jpg')

我不知道从哪个版本开始,但是关于a year ago枕头添加了文字描边功能。如果您最近没有更新,则可能需要更新。 stroke_width
为2的用法示例:
from PIL import Image, ImageDraw, ImageFont
caption = 'I need to update my Pillow'
img = Image.open('./example-img.jpg')
d = ImageDraw.Draw(img)
font = ImageFont.truetype('impact.ttf', size=50)
d.text((10, 400), caption, fill='white', font=font,
stroke_width=2, stroke_fill='black')
img.save('example-output.jpg')
答案 1 :(得分:3)
答案 2 :(得分:0)
@Abang指出,请使用stroke_width和stroke_fill。
代码:
from PIL import Image, ImageDraw, ImageFont
caption = 'Ans: stroke_width & stroke_fill'
img = Image.open('./example-img.jpg')
d = ImageDraw.Draw(img)
font = ImageFont.truetype('impact.ttf', size=50)
d.text((60, 400), caption, fill='white', font=font, spacing = 4, align = 'center',
stroke_width=4, stroke_fill='black')
img.save('example-output.jpg')
