### Description
when DOM API is not avaiable, using OffscreenCanvas
### Motivation and Context
In some environment like service worker or web worker, the DOM API is
not avaiable, we can use OffscreenCanvas API to replace
`document.createElement('canvas')`.
Most of the APIs of OffscreenCanvas and HTMLCanvasElement are the same,
except that `toDataUrl` is missing.
It fix this issues #19032
### Description
This PR contains a few changes in /js/common/ to support a coming PR for
a full implementation of webgpu IO binding.
- allows pass-through if value is already a Tensor instance in return
value of `handler.run()` called by `InferenceSession.run()`
(inference-session-impl.ts). Specifically, onnxruntime-node and
onnxruntime-react-native uses native bindings to generate a Tensor-like
object so we need to create a real Tensor instance here; for
onnxruntime-web the return value is already a Tensor instance.
- adds new types for GPU buffer supported types: `'float32'|'int32'` ->
`'float32'|'float16'|'int32'|'int64'|'uint32'|'bool'`
- exposes types `GpuBufferDataTypes` together with `CpuPinnedDataTypes`
and `TextureDataTypes` as exported
[//]: # (## Work In Progress. Feedbacks are welcome!)
### Description
This PR adds a few properties, methods and factories to Tensor type to
support IO-binding feature. This will allow user to create tensor from
GPU/CPU bound data without a force transferring of data between CPU and
GPU.
This change is a way to resolve#15312
### Change Summary
1. Add properties to `Tensor` type:
a. `location`: indicating where the data is sitting. valid values are
`cpu`, `cpu-pinned`, `texture`, `gpu-buffer`.
b. `texture`: sit side to `data`, a readonly property of `WebGLTexture`
type. available only when `location === 'texture'`
c. `gpuBuffer`: sit side to `data`, a readonly property of `GPUBuffer`
type. available only when `location === 'gpu-buffer'`
2. Add methods to `Tensor` type (usually dealing with inference
outputs):
- async function `getData()` allows user to download data from GPU to
CPU manually.
- function `dispose()` allows user to release GPU resources manually.
3. Add factories for creating `Tensor` instances:
a. `fromTexture()` to create a WebGL texture bound tensor data
b. `fromGpuBuffer()` to create a WebGPUBuffer bound tensor data
c. `fromPinnedBuffer()` to create a tensor using a CPU pinned buffer
### Examples:
create tensors from texture and pass to inference session as inputs
```js
// when create session, specify we prefer 'image_output:0' to be stored on GPU as texture
const session = await InferenceSession.create('./my_model.onnx', {
executionProviders: [ 'webgl' ],
preferredOutputLocation: { 'image_output:0': 'texture' }
});
...
const myImageTexture = getTexture(); // user's function to get a texture
const myFeeds = { input0: Tensor.fromTexture(myImageTexture, { width: 224, height: 224 }) }; // shape [1, 224, 224, 4], RGBA format.
const results = await session.run(myFeeds);
const myOutputTexture = results['image_output:0'].texture;
```
### Description
Set `canvas` dimensions to the `ImageBitmap` dimensions, thus fixing a
malformed Tensor creation.
### Motivation and Context
According to the [HTMLCanvasElement.drawImage()
spec](https://html.spec.whatwg.org/multipage/canvas.html#drawing-images):
> When the destination rectangle is outside the destination image (the
output bitmap), the pixels that land outside the output bitmap are
discarded, as if the destination was an infinite canvas whose rendering
was clipped to the dimensions of the output bitmap.
meaning that `ImageBitmap` pixels exceeding the canvas dimensions will
be discarded. Since no canvas dimensions are set for
`Tensor.fromImage(ImageBitmap)` if-case, the default 300x150px canvas
dimensions are used leading to the creation of malformed Tensors where
all the exceeding pixels are discarded and equal to `0, 0, 0, 0` during
the subsequent `pixels2DContext.getImageData()` call.
### Description
<!-- Describe your changes. -->
refactor tensor type in onnxruntime-common.
### Motivation and Context
There major motivation is that I am doing a local change to address the
API part of #15312. And I am doing a refactoring of onnxruntime-common
anyway (#15772).
The `tensor.ts` and `tensor-impl.ts` are too large, so I split contents
into multiple files to make the type declarations clearer.
The original target of this change is for API only ( ie. do not refactor
any implementation.). However, there are a few type/implementation
inconsistencies so I also made minimal changes to fix them.
### Changes
- extract `TensorUtils` for non-template interfaces
- extract `TensorFactory` for all overloads of `Tensor.fromImage()`
- refactor options type that used for `Tensor.fromImage()`
- fix JSDoc comments to make option descriptions consistent with actual
type declarations
- fix an inconsistency for `options.format` and `options.bitmapFormat`;
change all `bitmapFormat` to `format`
- extract `ConversionUtils` for `tensor.toDataURL()` and
`tensor.toImageData()`
- put implementations into multiple files from `tensor-impl.ts`
- fix a bug that cause unittest fail. put comments for future fix.
