The first change I made was to bump up the text size to something closer to the fonts used in a typical paperback book. I'm pretty happy with an html-user-font-size setting of 18, but 16 is also not too shabby. With the larger font, it makes sense to reduce the html-margin setting to 1 character to waste a minimal amount of space on the sides. To bad you can't set it to 1 or 2 pixels.
While I was working on the margins I decided to see what I could do about that big fat ugly scroll bar. The default G_SCROLL_BAR_WIDTH setting in setup.h is 12 pixels, which is extremely wasteful on the zipit. Simply reducing it by 4 pixels gives me another full line of text with a font size of 18.
The other thing that really bugs me about glinks is the ugly default battleship gray background color. You can change the colors of the menus, status bars, and even the scroll bar, but the html page background color must be set with in the document with a <body bgcolor="#FFFFDD"> tag or else you get the hard coded default_bg_g color from the default.c file. I may try to code up an html-default-bgcolor command line and config file option to set this at runtime, but for now I just compiled in a yellow tinged off white color #FFFFDD that reminds me an old paperback book.
Another thing I noticed was the occasional odd characters in the text. Turns out the books I fetched from Project Gutenberg are utf8 formatted. I wouldn't be surprised if all epub documents are utf8. Gotta review the specs someday. Anyhow, I simply added the html-assume-codepage utf8 setting to the zpub script and now all is right with the text. Check it out.
Gotta see if I can add that links command line option, then get the goodies posted and resume work on the bunjalloo code.
Update: That turned out to be pretty easy, just a few ifdefs in the default.c file. But now I've got a few more ideas. I read about a third of the "Little Fuzzy" novel last night, and when I put down the zipit I realized the links bookmark system is probably inadequate for ereading. I'd really like to save the scroll bar position so I can resume where I left off. I'm gonna see if I can use the M and R keys to Memorize and Recall a scroll bar bookmark. I might also look into defining the L and D keys in links to Lighten and Darken the LCD backlight for an adjustable day or night reading experience. Either that or I'll have to setup the keymap so I can switch to another virtual terminal to adjust the lights and maybe check the battery level.
Update 2: I finally finished reading my first full e-novel on the zipit and I can honestly say the experience was actually better than a paperback book in one way because I was able to pocket the zipit and take it with me. I did find and fix a bug in zpub during my test read that briefly prevented me from viewing the 2nd half of the novel. The M and R key scrollmark patch was fairly simple, and really made it easy to put down the zipit and pick it up again later to continue reading. I decided against patching dimmer keys into links because that should be done at a system level so all apps can benefit. I just need to work out which key combos make sense for all apps.
Here's the updated IZ2S zpub and links executables: zpub2-iz2s.zip
Here's the modified links sources: links-sdl-iz2s-zpub.tar.bz2
Here's a comprehensive patch for links-2.3 on the zipit: links-2.3-zipit.patch
And here's a patch with just the ereading modifications. http://pastebin.com/weJbzHWT
A jffs version will come later. I need to make a zpub-lite that works without bash, and bc. And I'll either have to provide a mini unzip executable, or build zpub-lite as an executable so I can use zlib. Maybe another mcb...
Bonjour,
ReplyDeleteMy prefered ebook reader is nupdf. I must have it too to refer to my pro tech datas at work. Because nupdf weights some MB, it will not fit in ffs, but the binary can be on a SD card (with some ebooks), and nupdf can be launched from iz2jffs with this little trick where I just made small the mandatory system part of the prog:

Now, with the plethora of readers and formats, the ebooks sites adapt, ex. this one let me build my own custom pdf !!!!

I have a Windows PC for work so I use sumatra pdf to read tech documents. I think it's based on the same mupdf code as nupdf, but you can see a lot more on a real computer screen. I'll have to take another look at nupdf. Maybe I'll add a bookmark feature if it doesn't have one already. I'm really happy with the bookmark, scrollbar, and background color patches to links. I expect to finish reading my first e-novel on the zipit by tomorrow. Up til now, I've only managed to finish a few short stories.
DeleteAt work...generally I work at home, and I have a big PC with a pair of 20' screens. My favorite PDF viewer is pdf-xchange-viewer, with it, I can annotate and edit my documents. Nupdf on the Z2 is to read some components pinouts on the go, it's really handy for me.
DeleteI'm impatient to test your new zpub, and to compare the two versions of a same book. And right, actually nupdf does not have bookmarking and backlight settings.
Happy reading !
