Image

The bytes of the image 'file'.

MIME content type for this image, e.g. 'image/jpeg' for a JPEG image.

The file extension for the image.

If an actual one is available from a load filename it is used. Otherwise a canonical extension is assigned based on the content type. Does not contain the leading period, e.g. 'jpg', not '.jpg'.

Original image file name, if loaded from disk, or a generic filename if loaded from an anonymous stream.

A Length value representing the native height of the image, calculated from the values of px_height and vert_dpi.

Integer dots per inch for the width of this image.

Defaults to 72 when not present in the file, as is often the case.

The vertical pixel dimension of the image.

The horizontal pixel dimension of the image.

SHA1 hash digest of the image blob.

Integer dots per inch for the height of this image.

Defaults to 72 when not present in the file, as is often the case.

A Length value representing the native width of the image, calculated from the values of px_width and horz_dpi.

Return a new Image subclass instance parsed from the image binary contained in blob.

Return a new Image subclass instance loaded from the image file identified by image_descriptor, a path or file-like object.

(cx, cy) pair representing scaled dimensions of this image.

The native dimensions of the image are scaled by applying the following rules to the width and height arguments.

• If both width and height are specified, the return value is (width, height); no scaling is performed.
• If only one is specified, it is used to compute a scaling factor that is then applied to the unspecified dimension, preserving the aspect ratio of the image.
• If both width and height are None, the native dimensions are returned.

The native dimensions are calculated using the dots-per-inch (dpi) value embedded in the image, defaulting to 72 dpi if no value is specified, as is often the case. The returned values are both Length objects.
