Tile rendering is currently possible from the API point of view, but in practice, rendering one tile takes almost the same time than rendering the whole page, so dividing the page in N tiles and render them separately is in the end much slower than rendering the whole page. This is due to the poppler rendering model, based on parse + render. We would need a model based on parsing the page to intermediate objects once and render multiple times using the intermediate objects. Similar to the render tree used by web engines.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
