When rendering big PDF pages at high zoom levels, we currently fall back to CSS zoom to avoid rendering canvases with too many pixels. This causes zoomed in PDF to look blurry, and the text to be potentially unreadable. This commit adds support for rendering _part_ of a page (called `PDFPageDetailView` in the code), so that we can render portion of a page in a smaller canvas without hiting the maximun canvas size limit. Specifically, we render an area of that page that is slightly larger than the area that is visible on the screen (100% larger in each direction, unless we have to limit it due to the maximum canvas size). As the user scrolls around the page, we re-render a new area centered around what is currently visible. |
