+# sharedTexture
+
+> Import shared textures into Electron and converts platform specific handles into [`VideoFrame`](https://developer.mozilla.org/en-US/docs/Web/API/VideoFrame). Supports all Web rendering systems, and can be transferred across Electron processes. Read [here](https://github.com/electron/electron/blob/main/shell/common/api/shared_texture/README.md) for more information.
+
+Process: [Main](../glossary.md#main-process), [Renderer](../glossary.md#renderer-process)
+
+## Methods
+
+The `sharedTexture` module has the following methods:
+
+**Note:** Experimental APIs are marked as such and could be removed in the future.
+
+### `sharedTexture.importSharedTexture(options)` _Experimental_
+
+* `options` Object - Options for importing shared textures.
+  * `textureInfo` [SharedTextureImportTextureInfo](structures/shared-texture-import-texture-info.md) - The information of the shared texture to import.
+  * `allReferencesReleased` Function (optional) - Called when all references in all processes are released. You should keep the imported texture valid until this callback is called.
+
+Imports the shared texture from the given options.
+
+> [!NOTE]
+> This method is only available in the main process.
+
+Returns `SharedTextureImported` - The imported shared texture.
+
+### `sharedTexture.sendSharedTexture(options, ...args)` _Experimental_
+
+* `options` Object - Options for sending shared texture.
+  * `frame` [WebFrameMain](web-frame-main.md) - The target frame to transfer the shared texture to. For `WebContents`, you can pass `webContents.mainFrame`. If you provide a `webFrameMain` that is not a main frame, you'll need to enable `webPreferences.nodeIntegrationInSubFrames` for this, since this feature requires [IPC](https://www.electronjs.org/docs/latest/api/web-frame-main#frameipc-readonly) between main and the frame.
+  * `importedSharedTexture` [SharedTextureImported](structures/shared-texture-imported.md) - The imported shared texture.
+* `...args` any[] - Additional arguments to pass to the renderer process.
+
+Send the imported shared texture to a renderer process. You must register a receiver at renderer process before calling this method. This method has a 1000ms timeout. Ensure the receiver is set and the renderer process is alive before calling this method.
+
+> [!NOTE]
+> This method is only available in the main process.
+
+Returns `Promise<void>` - Resolves when the transfer is complete.
+
+### `sharedTexture.setSharedTextureReceiver(callback)` _Experimental_
+
+* `callback` Function\<Promise\<void\>\> - The function to receive the imported shared texture.
+  * `receivedSharedTextureData` Object - The data received from the main process.
+    * `importedSharedTexture` [SharedTextureImported](structures/shared-texture-imported.md) - The imported shared texture.
+  * `...args` any[] - Additional arguments passed from the main process.
+
+Set a callback to receive imported shared textures from the main process.
+
+> [!NOTE]
+> This method is only available in the renderer process.
+
+## Properties
+
+The `sharedTexture` module has the following properties:
+
+### `sharedTexture.subtle` _Experimental_
+
+A [`SharedTextureSubtle`](structures/shared-texture-subtle.md) property, provides subtle APIs for interacting with shared texture for advanced users.

+# SharedTextureImportTextureInfo Object
+
+* `pixelFormat` string - The pixel format of the texture.
+  * `bgra` - 32bpp BGRA (byte-order), 1 plane.
+  * `rgba` - 32bpp RGBA (byte-order), 1 plane.
+  * `rgbaf16` - Half float RGBA, 1 plane.
+* `colorSpace` [ColorSpace](color-space.md) (optional) - The color space of the texture.
+* `codedSize` [Size](size.md) - The full dimensions of the shared texture.
+* `visibleRect` [Rectangle](rectangle.md) (optional) - A subsection of [0, 0, codedSize.width, codedSize.height]. In common cases, it is the full section area.
+* `timestamp` number (optional) - A timestamp in microseconds that will be reflected to `VideoFrame`.
+* `handle` [SharedTextureHandle](shared-texture-handle.md) - The shared texture handle.

+# SharedTextureImportedSubtle Object
+
+* `getVideoFrame` Function\<[VideoFrame](https://developer.mozilla.org/en-US/docs/Web/API/VideoFrame)\> - Create a `VideoFrame` that uses the imported shared texture in the current process. You can call `VideoFrame.close()` once you've finished using the object. The underlying resources will wait for GPU finish internally.
+* `release` Function - Release the resources. If you transferred and get multiple `SharedTextureImported` objects, you have to `release` every one of them. The resource on the GPU process will be destroyed when the last one is released.
+  * `callback` Function (optional) - Callback when the GPU command buffer finishes using this shared texture. It provides a precise event to safely release dependent resources. For example, if this object is created by `finishTransferSharedTexture`, you can use this callback to safely release the original one that called `startTransferSharedTexture` in other processes. You can also release the source shared texture that was used to `importSharedTexture` safely.
+* `startTransferSharedTexture` Function\<[SharedTextureTransfer](shared-texture-transfer.md)\> - Create a `SharedTextureTransfer` that can be serialized and transferred to other processes.
+* `getFrameCreationSyncToken` Function\<[SharedTextureSyncToken](shared-texture-sync-token.md)\> - This method is for advanced users. If used, it is typically called after `finishTransferSharedTexture`, and should be passed to the object which was called `startTransferSharedTexture` to prevent the source object release the underlying resource before the target object actually acquire the reference at gpu process asyncly.
+* `setReleaseSyncToken` Function - This method is for advanced users. If used, this object's underlying resource will not be released until the set sync token is fulfilled at gpu process. By using sync tokens, users are not required to use release callbacks for lifetime management.
+  * `syncToken` [SharedTextureSyncToken](shared-texture-sync-token.md) - The sync token to set.
