In the past, we discussed that error conditions such as this shouldn't throw exceptions. Most of the time, this type of error is just temporal and is resolved in the next frame. Rare exceptions are almost never caught by the author so the application crashes. Maybe for out of memory conditions, we could return a fake imagedata object with nothing but transparent white. In addition an 'isValid' property could signal if you have a real imagedata object.
