I have no problem waiting a second or two, although some experimentation shows that it is pretty fast opening a small pdf doc and even faster refreshing the image after M-x doc-view-enlarge. This is on Linux with a 2.4 GHz CPU. [snip] > Why are many files a problem for you? With that approach, opening a > document for the second time works instantly.

The problem with converting all the document to image files is that I often open large pdf's (several thousand pages) and small/medium dynamically generated pdf's. This would create tens of thousands of image files on a busy day (no exaggerating) which would require several gigabytes. Perhaps the most important problem with converting the full doc to image files is that it is a cpu and filesystem intensive process that can take a long time (think a fully illustrated 1000 page pdf). It steals cpu cycles on a busy machine (I often read while a long build or test suite is running) and drains battery on laptops/netbooks. [snip] IMHO, a user-configurable switch for "render this page and delete it before rendering the next" would be okay. More advanced options like keeping just the last N recently viewed pages of M documents (plus the succesive page of the current one) would be nice too, but if doc-view-mode supported the simple one-page option, it would be fine for me. P.D.: After some experimentation with doc-view it seems to me that the file image cache system is flawed: open a large pdf file -> doc-view starts conversion -> enlarge -> doc-view cancels previous conversion, throws away the files, and starts a new one -> shring -> cancel, throw and restart again, etc -> close the pdf view -> open the same pdf view -> if the cache I guess you thought that creating separate caches for every new zoom level would be too much caching :-) It seems there is a bug: open a large pdf -> before the conversion ends, kill the buffer -> open the pdf again -> the conversion is not resumed, only those pages converted on the previous session are accesible. -- Óscar _______________________________________________ Emacs-orgmode mailing list Remember: use `Reply All' to send replies to the list.
