That is not generally possible. It might, however, be possible if you are willing to put restrictions on as to what "text" is for your purposes. Are hieroglyphics "text" or "image" ?

It is not uncommon for greeting cards to use unusual fonts or to use script fonts; this will make your task more difficult.
Are the greeting cards in any specific language? The extraction process would likely differ between (say) Persian and (say) Old Norse.
