This shouldn't happen, i.e. we shouldn't even try to decode images when
extracting text, this is a waste of time and memory.
The cause is this in DrawObject:
{code}
PDXObject xobject = context.getResources().getXObject(name);
{code}
it results in the object being created and its contents being decoded.
