Description

When an imageView is created with an "images" property, iOS no longer respects the width and height specified by the imageView. In my case the image is drawn much larger and off the screen. It may be rendering the image to it's actual size, rather than scaling it to the dimensions specified. When the imageView specified a single image via the "image" property (non plural) iOS scales the image properly. On android imageViews will render the correct dimensions when either the "image" or "images" property is called. (Android works properly)

Hi Trevor, Can you please provide a reproducible sample test case?

Here is a sample in context to how I'm using it.

   
   var loaderDimensions = {width:492,height:35,scale:1}, // these are the dimensions of the original image
   	loaderMaxWidth = (2 * (Ti.Platform.displayCaps.platformWidth / 3)); // 2/3 of screen width
   
   loaderDimensions.scale = (loaderMaxWidth / loaderDimensions.width);
   
   loader = Ti.UI.createImageView({
   	top:0,
   	images:[
   		'/images/loaders/bar/1.png',
   		'/images/loaders/bar/2.png',
   		'/images/loaders/bar/3.png',
   		'/images/loaders/bar/4.png',
   		'/images/loaders/bar/5.png',
   		'/images/loaders/bar/6.png',
   		'/images/loaders/bar/7.png',
   		'/images/loaders/bar/8.png',
   		'/images/loaders/bar/9.png',
   		'/images/loaders/bar/10.png'
   	],
   	width:(loaderDimensions.width * loaderDimensions.scale),
   	height:(loaderDimensions.height * loaderDimensions.scale),
   	duration:50,
   	repeatCount:0
   });
   
   Ti.API.info('Loader Dimensions: ' + loader.width + ' x ' + loader.height);

Ti.API.info returns "[INFO] Loader Dimensions: 213.33333333333334 x 15.176151761517616" On iOS, the image appears to draw at full scale width:492,height:35 rather than the dimensions specified. I know it worked properly in an earlier version and it does work on android. Let me know if you want me to send you the images I'm using.
