Interface: Media
torchlive/media.Media
Methods
imageFromBlob
▸ imageFromBlob(blob, width, height): Image
deprecated This function will be removed in the next release. Use imageFromTensor instead.
const tensor = torch.fromBlob(blob, [imageHeight, imageWidth, channels]);
const image = media.imageFromTensor(tensor);
Converts a Blob into an Image. The blob should be in RGB format.
The width and height input should match the blob size.
i.e. blob.getDirectSize() equals width * height * 3.
Parameters
| Name | Type | Description |
|---|---|---|
blob | Blob | Blob to turn into an Image. |
width | number | The width of the image. |
height | number | - |
Returns
An Image object created from the Blob.
imageFromTensor
▸ imageFromTensor(tensor): Image
Converts a Tensor into an Image. The tensor should be in CHW (channels, height, width) format, with uint8 type.
There are some assumptions made about the input tensor:
- If the tensor has 4 channels, it is assumed to be RGBA.
- If the tensor has 3 channels, it is assumed to be RGB.
- If the tensor has 1 channel, it is assumed to be grayscale.
Parameters
| Name | Type | Description |
|---|---|---|
tensor | Tensor | Tensor to turn into an Image. |
Returns
An Image object created from the Tensor.
toBlob
▸ toBlob(obj): Blob
Converts a Tensor or NativeJSRef into a Blob. The blob can be used to create a Tensor object or convert into a NativeJSRef like an image or audio.
Parameters
| Name | Type | Description |
|---|---|---|
obj | NativeJSRef | Tensor | Object to turn into a Blob. |
