Re: w3mimgdisplay use?
* Kyle Wheeler [09.Kas.07 17:59 -0600]: n - ? This is used when displaying multiple images on a terminal window, and holds the index of the images in the cache. x - x coordinate to draw the image at (top left corner) y - y coordinate to draw the image at (top left corner) Correct. w - width to draw the image h - height to draw the image These are the width/height of the original image to draw. sx - ??? xy - ??? sw - width of the original (source) image sh - height of the original (source) image These parameters are for the actual image drawn on the window. Probably 's' stands for 'seen' or 'shown'. 'sx' and 'sy' are offsets from 'x' and 'y' respectively. After playing around, I figured out that sx and sy allow you to crop off parts of the top and left of the image... like it means start drawing from sx and sy in the image, which makes some sense. Yes, w3m uses these to redraw partly drawn images from cache when scrolling. I still can't figure out what n means, though. ...perhaps it has something to do with animated gifs? Animation frames are also drawn as separate images, so yes. But if you need to tweak these n and s parameters, I'd suggest calling w3m directly and letting it handle the details. -- ~sertaç

w3mimgdisplay use?
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hello, Does anyone know how to use w3mimgdisplay to display images on the terminal (or if its even possible)? I'm hoping to be able to put it in my mailcap so that when I view an attached image, it'll display it on the terminal. I've gotten as far as understanding that it has an input command language, so I can query the size of the image, like so: echo '5;./test.jpg' | w3mimgdisplay And I *believe* the command to display an image looks something like this: echo '0;1;2;3;4;5;6;7;8;9;./test.jpg' | w3mimgdisplay But as of yet, I haven't actually gotten it to display anything. Does anyone have any clues? Are there some magic incantations that must be performed first? Image-specific numbers that must be generated? What's the trick? ~Kyle P.S. Yes, I know that w3mimgdisplay has to be a persistent process, so the echo line up there won't *quite* work... but I'm still stumped as to what the correct behavior is. - -- If the president is the head of the American body politic, Congress is its gastrointestinal tract.

I figured it out by dissecting the X-Face patch by Tamo.

That's not true: it does not have to be a persistent process. It's just that w3m uses it as a persistent process to handle scrolling around without needing to keep fork()/exec()'ing all the time. This all said, while it's nifty and all, w3m is a nicer *viewer* because it handles all the scrolling and such.

Unfortunately, it doesn't seem to work for me---first, it won't compile against libexif 0.6.16-1 (the version in Ubuntu---it complains that exif_entry_get_value needs more arguments), second, my OSX box doesn't have framebuffer support (w3mimgdisplay appears to be calling the X11 libraries to do its business). I also looked at fbv, which has similar problems. It would appear that w3mimgdisplay is unusable (at least without modifying mutt) for auto_view'ing images, because mutt redraws the screen too much, and thus the image disappears as quickly as it's drawn. Ah, well... on the plus side, because w3mimgdisplay uses the X11 libraries, I can ssh into my main box and still view images! :D ~Kyle - -- To invent, you need a good imagination and a pile of junk. -- Thomas Jefferson -BEGIN PGP SIGNATURE- Comment: Thank you for using encryption! iD8DBQFHNPEgBkIOoMqOI14RAp51AKD03WTOKnVyTUaZ3t4/2ZhzdfpgGwCgnnAK f0oCKk9ABw75YLTxJyYvsUA= =KsrN -END PGP SIGNATURE-
