| +Screenshot Extension
|
| +--------------------
|
| +
|
| +This extension is to visually test the SDK examples. To use, add this to the
|
| +html:
|
| +
|
| +TODO(binji): normal users shouldn't have to do this -- it should be
|
| +automatically loaded by the testing framework.
|
| +
|
| + <head>
|
| + ...
|
| + <script
|
| + src="chrome-extension://kbbhhngcmjcmlgcnbihfgliliemmijmj/screenshot.js">
|
| + </script>
|
| + <head>
|
| +
|
| +Then in JavaScript:
|
| +
|
| + var myPluginEl = document.embeds[0];
|
| + function onSuccess(dataURL) {
|
| + // dataURL is a data URL encoded PNG. You can add this to a image like this:
|
| + var image = new Image();
|
| + image.onload = function() { ... }
|
| + image.src = dataURL;
|
| + }
|
| +
|
| + function onError(errorMessage) {
|
| + ...
|
| + }
|
| +
|
| + screenshot.captureElement(myPluginEl, onSuccess, onError);
|
| +
|
| +See screenshot.js for more info on the API.
