Security¶

An additional decompression bomb check has been added for the GIF format.

Deprecations¶

PyQt5 and PySide2¶

Deprecated since version 9.2.0.

Qt 5 reached end-of-life on 2020-12-08 for open-source users (and will reach EOL on 2023-12-08 for commercial licence holders).

Support for PyQt5 and PySide2 has been deprecated from ImageQt and will be removed in Pillow 10 (2023-07-01). Upgrade to PyQt6 or PySide6 instead.

FreeTypeFont.getmask2 fill parameter¶

Deprecated since version 9.2.0.

The undocumented fill parameter of FreeTypeFont.getmask2() has been deprecated and will be removed in Pillow 10 (2023-07-01).

PhotoImage.paste box parameter¶

Deprecated since version 9.2.0.

The box parameter is unused. It will be removed in Pillow 10.0.0 (2023-07-01).

Image.coerce_e¶

Deprecated since version 9.2.0.

This undocumented method has been deprecated and will be removed in Pillow 10 (2023-07-01).

Font size and offset methods¶

Deprecated since version 9.2.0.

Several functions for computing the size and offset of rendered text have been deprecated and will be removed in Pillow 10 (2023-07-01):

Deprecated	Use instead
`FreeTypeFont.getsize()` and `FreeTypeFont.getoffset()`	`FreeTypeFont.getbbox()` and `FreeTypeFont.getlength()`
`FreeTypeFont.getsize_multiline()`	`ImageDraw.multiline_textbbox()`
`ImageFont.getsize()`	`ImageFont.getbbox()` and `ImageFont.getlength()`
`TransposedFont.getsize()`	`TransposedFont.getbbox()` and `TransposedFont.getlength()`
`ImageDraw.textsize()` and `ImageDraw.multiline_textsize()`	`ImageDraw.textbbox()`, `ImageDraw.textlength()` and `ImageDraw.multiline_textbbox()`
`ImageDraw2.Draw.textsize()`	`ImageDraw2.Draw.textbbox()` and `ImageDraw2.Draw.textlength()`

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", font)

width, height = font.getsize_multiline("Hello\nworld")
width, height = draw.multiline_textsize("Hello\nworld", font)

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", font)

left, top, right, bottom = draw.multiline_textbbox((0, 0), "Hello\nworld", font)
width, height = right - left, bottom - top

Previously, the size methods returned a height that included the vertical offset of the text, while the new bbox methods distinguish this as a top offset.

In bbox methods, top measures the vertical distance above the text, while bottom measures that plus the vertical distance of the text itself. In size methods, height also measures the vertical distance above the text plus the vertical distance of the text itself.

If you are using these methods for aligning text, consider using Text anchors instead which avoid issues that can occur with non-English text or unusual fonts. For example, instead of the following code:

from PIL import Image, ImageDraw, ImageFont

font = ImageFont.truetype("Tests/fonts/FreeMono.ttf")

im = Image.new("RGB", (100, 100))
draw = ImageDraw.Draw(im)
width, height = draw.textsize("Hello world", font)
x, y = (100 - width) / 2, (100 - height) / 2
draw.text((x, y), "Hello world", font=font)

Use instead:

from PIL import Image, ImageDraw, ImageFont

font = ImageFont.truetype("Tests/fonts/FreeMono.ttf")

im = Image.new("RGB", (100, 100))
draw = ImageDraw.Draw(im)
draw.text((100 / 2, 100 / 2), "Hello world", font=font, anchor="mm")

API additions¶

Image.apply_transparency¶

Added 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.

Other changes¶

Using gnome-screenshot on Linux¶

In 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="".
