The text is text, but it's not easily reflowable. In practice, it's just the predefined shapes of the letters placed at specific locations of the page, there is no concept of words, lines or paragraphs in the text, just glyphs all around the page. That's what I meant with "
basically a picture". I don't mean it's a scanned page, but a set of "rules" to "draw" the page at some size. If you change the size the "rules" may not work so well. So still, it is a picture, not a bitmap picture maybe, but a vector picture.
