Description

Creating a View with a backgroundImage causes the image to appear low-res and pixelated. This is especially prominent on retina displays, but is noticeable on non-retina as well.

This was most probably caused by the fix for TIMOB-12593. We changed the magnification & minification the filters from linear to nearest

Sample test case for replicating. Using the attached graphic "lilypad.png", the image rendered as a backgroundImage of the View will have pixelated edges in comparision to the ImageView. The issue will be noticeable on simulator but is more pronounced on retina devices.

   var aWin = Ti.UI.createWindow({backgroundColor:'#fff'});
   var viewWithBG = Ti.UI.createView({
   	height:100, width:250, top:10, left:10,
   	backgroundImage:'lilypad.png'
   });
   var imageView = Ti.UI.createImageView({
   	height:100, width:250, top:10, left:280,
   	image:'lilypad.png'
   });
   aWin.add(viewWithBG);
   aWin.add(imageView);
   aWin.open();
