Text Height

[Nazar1ky]

Hello, I read docs but I get confused how to get text height. Here is my representation code:

import pymupdf

with pymupdf.open() as doc:
    page = doc.new_page(height=200, width=200)

    # Load Segoe UI fonts
    font_bold = pymupdf.Font(fontfile="C:/Windows/Fonts/segoeuib.ttf")
    page.insert_font(fontname="segoeuib", fontbuffer=font_bold.buffer)

    fs = 10
    height = (font_bold.ascender - font_bold.descender) * fs
    page.insert_text((0, height), "ÊQXxbdpqgy(@_`[]{})⭐🤣", fontname="segoeuib", fontsize=fs)

    doc.save("test.pdf")

The result I got is not ideally at 0, 0. Maybe I doing something wrong?

Thanks!

The (0, height) is the insertion point = "origin"! This is higher up than the bbox.y1.
Use (0, font.ascender * fs) instead.

But for Emoji font it works a bit different, is there way to get bbox?

[JorjMcKie]

Why should it be different?

Hi. Sorry for late answer.

font_emoji = pymupdf.Font(fontfile="C:/Windows/Fonts/seguiemj.ttf")
page.insert_font(fontname="segoeuimj", fontbuffer=font_emoji.buffer)

page.insert_text((0, font_emoji.ascender * fs), "ÊQXxbdpqgy(@_`[]{})⭐🤣", fontname="segoeuimj", fontsize=fs, color=(0.5,))

The Ê is not showed fully, and emoji too.

That's the fault of the font maker.

Alright thank you!
