This happens because Titanium recognizes the image as a 9-patch image.

When opening the local image resource, Titanium checks whether it is a 9-patch image in TiNinePatchHelper.java.

If the 1-pixel edge of the image contains only black and transparent color, it recognizes as a 9-patch image.

So if you want to avoid the error, the border of the image should contain at least one pixel with other color, such as black pixel with a little bit transparency.
