Hello Alexandr,

Please review the updated webrev.

http://cr.openjdk.java.net/~rchamyal/8150176/webrev.02/ <http://cr.openjdk.java.net/%7Erchamyal/8150176/webrev.02/>

WTrayIconPeer.java
+ gr.drawImage(image, 0, 0, (autosize ? w : image.getWidth(observer)), + (autosize ? h : image.getHeight(observer)), observer);

The w and h are scaled. It looks like the image.getWidth(observer) and image.getHeight(observer) also should be scaled in the same way.

 MultiResolutionTrayIconTest.java
+        latch.await();

It is better to add a timeout here.

Thanks,
Alexandr.

Update: Updated webrev is fixing the issue in windows only.

We have a separate bug linux and it will be fixed through a separate webrev.

    Hello Alexandr,

    Thanks for the review. I have updated the webrev as per review
    comments.

    I tried drawing the image directly to paint graphics without
    buffered image and it was getting cropped.


Did you paint it using non scaled width and height?
  g.drawImage(image, 0, 0, curW, curH, null);
Is the g transform already scaled?

XTrayIconPeer:

606                 if (scaleX > 1.0 && scaleY > 1.0) {
607 resolutionVariant = ((MultiResolutionImage) image).


It is better to change the condition to "image instanceof MultiResolutionImage". It is necessary to not get CCE for non multi-resolution image and the multi-resolution image should return the best resolution variant for any scale.

618                         gr.drawImage(resolutionVariant, 0, 0,
619                                 curW, curH, observer);

The width and height should be scaled here to draw to whole buffered image.

WTrayIconPeer:

133 BufferedImage bufImage = new BufferedImage(TRAY_ICON_WIDTH, TRAY_ICON_HEIGHT,
 134 BufferedImage.TYPE_INT_ARGB);

The size for the buffered image should be scaled in the same was as for XTrayIconPeer. It may require to update the native code as well to set proper high-resolution icon.

Thanks,
Alexandr.

        Hello All,

        Please review the following fix.

        Bug: https://bugs.openjdk.java.net/browse/JDK-8150176

        Webrev:
        http://cr.openjdk.java.net/~rchamyal/8150176/webrev.00/
        <http://cr.openjdk.java.net/%7Erchamyal/8150176/webrev.00/>

        Issue: Wrong resolution variant image is used in Tray Icon.

        Fix : Applying the device transform to graphics object to
        select the correct image.

        The image could be cropped on Linux because the high
    resolution icon which size is bigger that the original image is
    drawn to the buffered image with un-scaled size curW x CurH.
      It is better to get a resolution variant from the
    multi-resolution image, draw it to a buffered image with the same
    scaled size and then draw the buffered image to the paint graphics
    using original size:
        -------
        Image resolutionVariant = ((MultiResolutionImage)
    image).getResolutionVariant(scaleX * curW, scaleY * curH);
        BufferedImage bufImage = new BufferedImage(scaleX * curW,
    scaleY * curH, BufferedImage.TYPE_INT_ARGB);
        // ...
        gr.drawImage(image, 0, 0, scaleX * curW, scaleY * curH, observer);
        // ...
        g.drawImage(bufImage, 0, 0, curW, curH, observer); // non
    scaled width and height
        -------

      By the way, is the buffered image necessary in this case? Is it
    possible to draw the image directly to the paint graphics?
        -------
         g.drawImage(image, 0, 0, curW, curH, null);
        -------

    Thanks,
    Alexandr.
