getbbox incorrect when string contains new line character

[vanviethieuanh]

What did you do?

So I use the getbbox to calculate the width and height of my string with a specific font. The string includes the \n character and it split the line into 2.

What did you expect to happen?

The string renders well and has a width of about 7xx pixels which is what I want. And I expect the getbbox function returns the same value.

What actually happened?

However, the result I got from getbbox is 1555 pixels which might be the width of no break line text.

What are your OS, Python, and Pillow versions?

• OS: Windows 10 Enterprise
• Python: Python 3.10.10
• Pillow: 9.4.0

text = "Age is an issue of mind over matter.\nIf you don't mind, it doesn't matter."
_, _, text_width, text_height = FONT.getbbox(text)
# text_width = 1555

The size of the image is 1080*1080 so there is no way that the text width is 1555.

Thank you!

Line breaking is handled only in ImageDraw and not in ImageFont; you should use ImageDraw.multiline_textbbox(). The thread around #5816 (comment) might interest you.

@vanviethieuanh did that answer your question?
