https://bugbase.adobe.com/index.cfm?event=bug&id=3161013

Adobe AIR 3.8 relase notes, notable bug fixes:

StageWebView.drawViewPortToBitmapData draws incorrect bitmap on retina devices(3558603)

But this is still an issue on AIR 13.0.0.42 at Galaxy S3 (Android 4.3)

How to solve this problem?

There is an example test file (.fla) at zip: Link

here is the code:

import flash.display.Bitmap;

import flash.display.BitmapData;

import flash.events.MouseEvent

import flash.geom.Rectangle;

import flash.media.StageWebView;

var webView:StageWebView = new StageWebView();

webView.viewPort = new Rectangle(0,0,stage.stageWidth,stage.stageHeight-100);

webView.stage = this.stage;

webView.loadURL("http://labs.adobe.com/");

var webViewBitmap:Bitmap;

addBitmap.addEventListener(MouseEvent.CLICK, addBitmapClickHandler);

removeBitmap.addEventListener(MouseEvent.CLICK, removeBitmapClickHandler);

function addBitmapClickHandler(event:MouseEvent):void

{

          var rect:Rectangle = webView.viewPort;

          var bitmapData:BitmapData = new BitmapData(rect.width,rect.height,true,0xff0000);

          webView.drawViewPortToBitmapData(bitmapData);

          webViewBitmap = new Bitmap(bitmapData);

          webView.stage = null;

          addChild(webViewBitmap);

}

function removeBitmapClickHandler(event:MouseEvent):void

{

          if (contains(webViewBitmap))

                    removeChild(webViewBitmap);

          webView.stage = this.stage;

}

Thanks for reporting the issue, could you please try putting in “NO_SCALE” in your code as following?

stage.scaleMode = StageScaleMode.NO_SCALE;

Yes, it is working fine, thanks.

But i should publish the mobile application for IOS/Android with the code as following:

stage.scaleMode = StageScaleMode.EXACT_FIT

So how can i do to draw the correct bitmap from webview?

Or how can i calculate to the correct viewport from webview?

[Colin Holgate]

There are many cases where no_scale would not be appropriate, so it doesn’t really help if it solves the issue here.

Also, what is a mobile use case for exact_fit? As that would distort the stage, it could well be the cause of the problems you’re having.

How do things look if you use the default of show_all or you use no_border?

I have been testing on Galaxy S3 and encountering same issue which is 2x zoomed snapshot when i use StageScaleMode.SHOW_ALL, StageScaleMode.NO_BORDER or StageScaleMode.EXACT_FIT.

I have been getting correct result when i use StageScaleMode.NO_SCALE but this time StageWebview seems near the middle of the device.

What can i do in this case?

İ have been checking this issue but still an issue on AIR 13.0.0.55 which publised on labs page at 6 March.
