Small container fields render black bar that is not part of image data
Operating system version
Mac OS X 10.9.1
Description of the issue
Some images are rendered with a thin black bar at the bottom of the image when they are rendered in a small container field. When the exact same container field is enlarged, the black bar disappears. This does not happen for all images. The same phenomenon occurs in FileMaker Go. I uploaded a sample file with images that behave this way here: https://www.dropbox.com/s/kxo7fqjm05dvcrl/Container%20Bug%20Demo.fmp12.zip
Steps to reproduce the problem
Place an image in a small container field.
The image should be rendered faithfully.
A thin black bar is displayed at the bottom of the image.
Exact text of any error message(s) that appear
Making the container field object larger will often make FileMaker re-draw the image without the thin black bar, but the same resizing will not fix the issue for all images.
