|
``FreeTypeFont.getsize_multiline()`` :py:meth:`.ImageDraw.multiline_textbbox`
|
|

Previous code::
|
|
|
|
from PIL import Image, ImageDraw, ImageFont
|
|
|
|
font = ImageFont.truetype("Tests/fonts/FreeMono.ttf")
|
|
width, height = font.getsize("Hello world")
|
|
left, top = font.getoffset("Hello world")
|
|
|
|
im = Image.new("RGB", (100, 100))
|
|
draw = ImageDraw.Draw(im)
|
|
width, height = draw.textsize("Hello world")
|
|
|
|
width, height = font.getsize_multiline("Hello\nworld")
|
|
width, height = draw.multiline_textsize("Hello\nworld")
|
|
|
|
Use instead::
|
|
|
|
from PIL import Image, ImageDraw, ImageFont
|
|
|
|
font = ImageFont.truetype("Tests/fonts/FreeMono.ttf")
|
|
left, top, right, bottom = font.getbbox("Hello world")
|
|
width, height = right - left, bottom - top
|
|
|
|
im = Image.new("RGB", (100, 100))
|
|
draw = ImageDraw.Draw(im)
|
|
width = draw.textlength("Hello world")
|
|
|
|
left, top, right, bottom = draw.multiline_textbbox((0, 0), "Hello\nworld")
|
|
width, height = right - left, bottom - top
|
|
|
|
API Additions
|
|
=============
|
|
|
|
Image.apply_transparency
|
|
^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Added :py:meth:`~PIL.Image.Image.apply_transparency`, a method to take a P mode image
|
|
with "transparency" in ``im.info``, and apply the transparency to the palette instead.
|
|
The image's palette mode will become "RGBA", and "transparency" will be removed from
|
|
``im.info``.
|
|
|
|
Security
|
|
========
|
|
|
|
An additional decompression bomb check has been added for the GIF format.
|
|
|
|
Other Changes
|
|
=============
|
|
|
|
Using gnome-screenshot on Linux
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
In :py:meth:`~PIL.ImageGrab.grab` on Linux, if ``xdisplay`` is ``None`` then
|
|
``gnome-screenshot`` will be used to capture the display if it is installed. To capture
|
|
the default X11 display instead, pass ``xdisplay=""``.
