Subject: fast image paging
Date: Mon, 11 Nov 2013 15:08:47 -0500 [thread overview]
Message-ID: <87mwlabt0w.fsf@happiness.m.enhanced.com> (raw)
Greetings! I have a djvu mode which is designed for scholars reading,
annotating, and cross-referencing many large documents. Right now I use
pbm formats and create-image. This makes it easy to highlight and
correlate pixels with text, but the images can get quite large, making
handling sluggish on slower machines.
Will I improve anything here using a compressed format like png? Or,
when emacs displays and moves the image, does it decompress the image
anyway into the same sized internal data structure?
Take care,
--
