Description

Hello, In Android, blob.getWidth() returns wrong width value in imageView.

Step To Reproduce

1. Put a image in assets/android folder. 2. Use the below Code. 3. Make the change in image name. 4. Run the project. index.xml

<Alloy>
	<Window class="container">
	</Window>
</Alloy>

index.js

var imgView = Ti.UI.createImageView({image:'/images/img_yo_face.png'});
var blob = imgView.toImage();

Titanium.API.info (blob.getWidth());

$.index.open();

Observed result

In console the "Titanium.API.info (blob.getWidth());" return value is 1.

Expected result

"Titanium.API.info (blob.getWidth());" should return the aclual width value. Regards, Sharif

toImage() is used when you want to transform a view into a bitmap. The view's width and height won't be measure until it is visible on screen. Since the above example did not add the imageView to any window/view, width and height values are not true values. Since you have an imageView, if you want the bitmaps bounds, you can use: imgView.toBlob(); That should work even when the view isn't visible.
