# 8.0.0

## Backwards Incompatible Changes

### Python 3.5

Pillow has dropped support for Python 3.5, which reached end-of-life on 2020-09-13.

### PyPy 7.1.x

Pillow has dropped support for PyPy3 7.1.1. PyPy3 7.2.0, released on 2019-10-14, is now the minimum compatible version.

### im.offset

`im.offset()` has been removed, call `ImageChops.offset()` instead.

### Image.fromstring, im.fromstring and im.tostring

- `Image.fromstring()` has been removed, call `Image.frombytes()` instead.

- `im.fromstring()` has been removed, call `frombytes()` instead.

- `im.tostring()` has been removed, call `tobytes()` instead.

### ImageCms.CmsProfile attributes

Some attributes in `PIL.ImageCms.CmsProfile` have been removed:

Removed | Use instead
--- | ---
`color_space` | Padded `xcolor_space`
`pcs` | Padded `connection_space`
`product_copyright` | Unicode `copyright`
`product_desc` | Unicode `profile_description`
`product_description` | Unicode `profile_description`
`product_manufacturer` | Unicode `manufacturer`
`product_model` | Unicode `model`

## API Changes

### ImageDraw.text: stroke_width

Fixed issue where passing `stroke_width` with a non-zero value to `ImageDraw.text()` would cause the text to be offset by that amount.

### ImageDraw.text: anchor

The `anchor` parameter of `ImageDraw.text()` has been implemented.

Use this parameter to change the position of text relative to the specified `xy` point. See Text anchors for details.

### Add MIME type to PsdImagePlugin

“image/vnd.adobe.photoshop” is now registered as the `PsdImagePlugin.PsdImageFile` MIME type.

## API Additions

### Image.open: add formats parameter

Added a new `formats` parameter to `Image.open()`:

- A list or tuple of formats to attempt to load the file in. This can be used to restrict the set of formats checked. Pass `None` to try all supported formats. You can print the set of available formats by running `python3 -m PIL` or using the `PIL.features.pilinfo()` function.

### ImageOps.autocontrast: add mask parameter

`ImageOps.autocontrast()` can now take a `mask` parameter:

- Histogram used in contrast operation is computed using pixels within the mask. If no mask is given the entire image is used for histogram computation.

### ImageOps.autocontrast cutoffs

Previously, the `cutoff` parameter of `ImageOps.autocontrast()` could only be a single number, used as the percent to cut off from the histogram on the low and high ends.

Now, it can also be a tuple `(low, high)`.

### ImageDraw.regular_polygon

A new method `ImageDraw.regular_polygon()`, draws a regular polygon of `n_sides`, inscribed in a `bounding_circle`.

For example `draw.regular_polygon(((100, 100), 50), 5)` draws a pentagon centered at the point `(100, 100)` with a polygon radius of `50`.

### ImageDraw.text: embedded_color

The methods `ImageDraw.text()` and `ImageDraw.multiline_text()` now support fonts with embedded color data.

To render text with embedded color data, use the parameter `embedded_color=True`.

Support for CBDT fonts requires FreeType 2.5 compiled with libpng. Support for SBIX fonts requires FreeType 2.5.1 compiled with libpng. Support for COLR fonts requires FreeType 2.10. SVG fonts are not yet supported.

### ImageDraw.textlength

Two new methods `ImageDraw.textlength()` and `FreeTypeFont.getlength()` were added, returning the exact advance length of text with 1/64 pixel precision.

These can be used for word-wrapping or rendering text in parts.

### ImageDraw.textbbox

Three new methods `ImageDraw.textbbox()`, `ImageDraw.multiline_textbbox()`, and `FreeTypeFont.getbbox()` return the bounding box of rendered text.

These functions accept an `anchor` parameter, see Text anchors for details.

## Other Changes

### Improved ellipse-drawing algorithm

The ellipse-drawing algorithm has been changed from drawing a 360-sided polygon to one which resembles Bresenham’s algorithm for circles. It should be faster and produce smoother curves, especially for smaller ellipses.

### ImageDraw.text and ImageDraw.multiline_text

Fixed multiple issues in methods `ImageDraw.text()` and `ImageDraw.multiline_text()` sometimes causing unexpected text alignment issues.

The `align` parameter of `ImageDraw.multiline_text()` now gives better results in some cases.

TrueType fonts with embedded bitmaps are now supported.

### Added writing of subIFDs

When saving EXIF data, Pillow is now able to write subIFDs, such as the GPS IFD. This should happen automatically when saving an image using the EXIF data that it was opened with, such as in `exif_transpose()`.

Previously, the code of the first tag of the subIFD was incorrectly written as the offset.

### Error for large BMP files

Previously, if a BMP file was too large, an `OSError` would be raised. Now, `DecompressionBombError` is used instead, as Pillow already uses for other formats.

### Dark theme for docs

The https://pillow.readthedocs.io documentation will use a dark theme if the the user has requested the system use one. Uses the `prefers-color-scheme` CSS media query.
