I am pretty sure that this is not indeed a limitation of the translator 
API. There was one image shower on BeBits that supported progressive 
display. The trick is probably to not use BTranslationUtils::GetBitmap(), 
but use translators directly, and then write your own BDataIO that calls 
back into your app to render partial bitmaps during the conversion.

Best regards,
