Resize the input image to the given size. If the image is torch Tensor, it is expected to have […, H, W] shape, where … means a maximum of two leading dimensions
size (sequence or int) –
Desired output size. If size is a sequence like (h, w), output size will be matched to this. If size is an int, smaller edge of the image will be matched to this number. i.e, if height > width, then image will be rescaled to (size * height / width, size).
Note
In torchscript mode size as single int is not supported, use a sequence of length 1: [size, ]
.
interpolation (InterpolationMode) – Desired interpolation enum defined by torchvision.transforms.InterpolationMode
. Default is InterpolationMode.BILINEAR
. If input is Tensor, only InterpolationMode.NEAREST
, InterpolationMode.NEAREST_EXACT
, InterpolationMode.BILINEAR
and InterpolationMode.BICUBIC
are supported. The corresponding Pillow integer constants, e.g. PIL.Image.BILINEAR
are accepted as well.
max_size (int, optional) – The maximum allowed for the longer edge of the resized image. If the longer edge of the image is greater than max_size
after being resized according to size
, size
will be overruled so that the longer edge is equal to max_size
. As a result, the smaller edge may be shorter than size
. This is only supported if size
is an int (or a sequence of length 1 in torchscript mode).
antialias (bool, optional) –
Whether to apply antialiasing. It only affects tensors with bilinear or bicubic modes and it is ignored otherwise: on PIL images, antialiasing is always applied on bilinear or bicubic modes; on other modes (for PIL images and tensors), antialiasing makes no sense and this parameter is ignored. Possible values are:
True
(default): will apply antialiasing for bilinear or bicubic modes. Other mode aren’t affected. This is probably what you want to use.
False
: will not apply antialiasing for tensors on any mode. PIL images are still antialiased on bilinear or bicubic modes, because PIL doesn’t support no antialias.
None
: equivalent to False
for tensors and True
for PIL images. This value exists for legacy reasons and you probably don’t want to use it unless you really know what you are doing.
The default value changed from None
to True
in v0.17, for the PIL and Tensor backends to be consistent.
