*This patch implements https://github.com/mozilla/pdf.js/pull/11777#issuecomment-609741348* This extends the work from PR 11773 and 11777 further, by immediately releasing the `font.data` property once the font been attached to the DOM. By not unnecessarily holding onto this data on the main-thread, we'll thus reduce the memory usage of fonts even further (especially beneficial in longer documents with composite fonts). The new behaviour is controlled by the recently added `fontExtraProperties` API option (adding a new option just for this patch didn't seem necessary), since there's one edge-case in the SVG renderer where the `font.data` property is necessary (see the `pdf2svg` example). Note that while the default viewer does run clean-up with an idle timeout, that timeout will be reset whenever rendering occurs *or* when scrolling happens in the viewer. In practice this means that unless the user doesn't interact with the viewer in *any* way during an extended period of time, currently set to 30 seconds, the `PDFDocumentProxy.cleanup` method will never be called and font resources will thus not be cleaned-up. |
