clipboard.setImageData()

将图像复制到剪贴板。在将图像写入剪贴板之前，会对图像进行重新编码。如果图像无效，则不会修改剪贴板。

图像被作为包含经过编码的图像的 ArrayBuffer 提供。支持 JPEG 和 PNG 格式。

基于 Chrome 的 clipboard.setImageData() API，但存在一些差异：

• Chrome API 仅适用于应用，不适用于扩展程序。
• 此API需要 "clipboardWrite" 权限，Chrome 版本需要 "clipboard" 权限。
• Chrome 的 API 使用回调，此 API 使用 Promise。
• 此 API 不支持 additionalItems 参数。

这是一个返回 Promise 的异步函数。

browser.clipboard.setImageData(imageData, imageType)

imageData

An ArrayBuffer containing the encoded image data to copy to the clipboard.

imageType

A DOMString indicating the type of image contained in imageData: "png" or "jpeg".

A Promise that will be resolved with no arguments if the operation succeeded, or rejected if there was an error (for example, because the data did not represent a valid image).

Copy a remote image:

// requires:
// * the host permission for "https://cdn.mdn.mozilla.net/*"
// * the API permission "clipboardWrite"

fetch('https://cdn.mdn.mozilla.net/static/img/favicon144.png')
.then(response => response.arrayBuffer())
.then(buffer => browser.clipboard.setImageData(buffer, 'png'));

Copy an image that was bundled with the extension:

// requires the API permission "clipboardWrite"

fetch(browser.runtime.getURL('image.png'))
.then(response => response.arrayBuffer())
.then(buffer => browser.clipboard.setImageData(buffer, 'png'));
