PIL how to scale image in relation to the text drawn on image

Question

I am trying to dynamically increase image size with respect to font and text given to draw.text().

Orignal Problem is to create signature image based on name and the font user selects.

Here is my code

from PIL import (Image, ImageDraw, ImageFont,)

width=20
height=20
selected_font='simply_glomrous.ttf'
font_size=30

img = Image.new('RGBA', (width, height), (255, 255, 255, 0))
draw = ImageDraw.Draw(img)
font = ImageFont.truetype(selected_font, font_size)
draw.text((0,0), "Adil Malik", (0,0,0), font)
img.save('signature.png')

But i am still having same image size defined in width and height. Can we do dynamically resizing of image based on font and its size ?

Note: This question is opposite to this stackoverflow question

Answer 1

Unfortunately, No one able to answer my question.

Basically, You can't set fix width and height while setting the font size. Both are dependent on each other. So if one increase, second one also increases.

So I have come up with another solution. I am just setting the font size and then based on that font size, I am setting width and height.

from PIL import (Image, ImageDraw, ImageFont,)

name = 'Adil Malik'
selected_font='simply_glomrous.ttf'
font_size=30

font = ImageFont.truetype(selected_font, font_size)
font_size = font.getsize(name)

img = Image.new('RGBA', (font_size[0], font_size[0]), (255, 255, 255, 0))
draw = ImageDraw.Draw(img)
font = ImageFont.truetype(selected_font, font_size)
draw.text((0,0), name, (0,0,0), font)
img.save('signature.png')
