Description Jon Douglas [MSFT] 2014-08-27 12:41:56 UTC
When scaling an image, the image becomes offset to the left instead of staying centered.

This does work on X.Forms 1.0.X as I tested it there first. However this seems to be a regression issue.

I have checked this issue and unable to reproduce it.

I have tried following steps to reproduce it.
1.Create a Xamarin form  application.
2.Add a class(.cs) file and Did some coding in it.
3.Call class(.cs) in App.cs
4.Run the application.

I observed that after varying Scale value Image stayed in centered.

Arpit,

But you were running the iOS project, not Android. Change the startup project to the Android one, run it, and you will see the bug.
Comment 3 Arpit Jha 2014-08-28 11:04:49 UTC
I have checked this issue again and able to reproduce it.

I have tried above mentioned steps.

Set Startup Project xamrin.android.

I observed that after Scaling Image becomes offset to Left instead of Centered.

Comment 4 daniel 2014-09-06 09:05:36 UTC
I get this same issue but with a scaled Label within a ListView
Comment 5 Jason Smith [MSFT] 2014-09-06 09:32:54 UTC
If your intention was to scale with the top left corner staying in teh same position you need to set AnchorX and AnchorY to 0,0. The default values are .5,.5 which results in scaling/rotation happening about the center and not the top-left.

Please re-open if this does not resolve your issue.
Comment 6 daniel 2014-09-06 14:35:33 UTC
No, the intention was to scale with the center staying centered.  (Which does not work).  Most of the items that are scaled are offset to the left and some of them are still centered but the scaling has not been applied.  It works perfectly on iOS but on Android the scaling within a listview seems to be broken.
Comment 7 Jason Smith [MSFT] 2014-09-06 16:57:30 UTC
will look into
Comment 8 Jason Smith [MSFT] 2015-01-18 04:26:02 UTC
This should no longer happen
