write_jpeg

torchvision.io.write_jpeg(input: Tensor, filename: str, quality: int = 75) → Tensor

[DEPRECATED] Use TorchCodec instead.

Takes an input tensor in CHW layout and saves it in a JPEG file.

Warning

The image decoding and encoding capabilities of TorchVision are deprecated since torchvision 0.29 and will be removed in a future release. They are superseded by the more complete decoders and encoders of TorchCodec (from torchcodec 0.16). Please see this migration guide on how to migrate your code.

Parameters:

• input (Tensor[channels, image_height, image_width]) – int8 image tensor of c channels, where c must be 1 or 3.

• filename (str or pathlib.Path) – Path to save the image.

• quality (int) – Quality of the resulting JPEG file, it must be a number between 1 and 100. Default: 75

Returns:

the JPEG-encoded data that was written to the file.

Return type:

output (Tensor)
