Xpdf Zoom Levels
« on: March 26, 2007, 01:25:05 pm »
I have the latest xpdf 3.0.1-1 installed and want to know if there is a way to get a zoom level between 100% and 125% ?
As shown in the screenshots below in meanie's zbook3k.pdf, there is extra space being wasted (at 100%) in the margins.
At this zoom level, the text is tiny.
If I zoom to 125%, the zoom level is too much and now I have to scroll horizontally, but the text is much more readable.
I would like to see zoom levels in increments of:
105%
110%
115%
120%

pic 1 (xpdf @ 100%)
pic 2 (xpdf @ 125%)

I use the command line xpdf -z 111 my.pdf to get i.e. 11% magnification.
If you read a longer book that you start repeatedly an alias will work fine.

Thanks, I tried that and it seems I'm missing some fonts.
xpdf opened the file in 100% zoom instead of 115% as I specified
Code: [Select]

The "fit width" zoom option isn't working for you?

"Fit width" includes the margins, which is blank white space. I wanted to zoom in and eliminate the margins to make the fonts larger without making the fonts go off the viewing area. "Fit to width" is almost the same as 100% in this instance.

Does this actually work for anyone?  You could zoom in increments of 1%?  It should work for the PDF file format.  

dsteurer:  could you please tell us which xpdf version you're using, and where it could be downloaded?

Thanks very much for this info.  Unfortunately, recompiling xpdf3.02 in this manner has so far led me to the loss of the middle mouse panning.  I think this might be a problem with the new keybindings in ~/.xpdfrc....

I'm going a bit off topic here, but Picsel browser for Zaurus has infinite zoom levels up to it's largest zoom level.
There is 2 things that Picsel browser won't do, and that is:
1. It won't install or work in pdaxrom or pdaxii13
2. In sharp/Cacko, it opens and displays every PDF file that I can throw at it except for one. That one is meanie's zbook3k.pdf

KPDF will do the same (albeit very slowly).  Is it in the feeds?  Haven't used it in a long time due to it's lack of speed.  I still like XPDF for most everything.  It's lean and mean, but really under featured.  

What's keeping Picsel Browser from pdaxrom?  

EDIT:  nevermind, (I googled and found some answers)  Wow, that's an expensive system  I'm sorry it doesn't work in pdaxrom.

[div align=\"right\"][a href=\"index.php?act=findpost&pid=158056\"][{POST_SNAPBACK}][/a][/div]

following ShiroiKuma's example, do the following:

edit xpdf-3.02/xpdf/XPDFViewer.cc

Starting at line 141, you'll see the following text:

static ZoomMenuInfo zoomMenuInfo[nZoomMenuItems] = {
{ "400%", 400 },
{ "200%", 200 },
{ "150%", 150 },
{ "125%", 125 },
{ "100%", 100 },
{ "50%", 50 },
{ "25%", 25 },
{ "12.5%", 12.5 },
{ "fit page", zoomPage },
{ "fit width", zoomWidth }
};

change it to:

static ZoomMenuInfo zoomMenuInfo[nZoomMenuItems] = {
{ "400%", 400 },
{ "200%", 200 },
{ "150%", 150 },
{ "125%", 125 },
{ "120%", 120 },
{ "115%", 115 },
{ "110%", 110 },
{ "105%", 105 },
{ "100%", 100 },
{ "50%", 50 },
{ "25%", 25 },
{ "12.5%", 12.5 },
{ "fit page", zoomPage },
{ "fit width", zoomWidth }
};

edit xpdf-3.02/xpdf/XPDFViewer.h

and change

#define nZoomMenuItems 10

to

#define nZoomMenuItems 14

There is one way to get the best view:

Use fullscreen first, then use the stylus to select a line or paragraph with exact length of the words, then right click (Fn+tap), choose "Zoom to selection". Then what you'll see is something like this:  

(yes, this is the Z screen. no window, no scrollbar  )

[img]http://farm1.static.flickr.com/236/453424390_c16a59e45b_o.png\" border=\"0\" class=\"linked-image\" /]

By the way I've built an optimized XPDF with 23 zooming levels (thanks to Meanie's tips). Will put up here shortly.
Next is to figure out how to get the now detached CMap things working to display Asian language  fonts.

I couldn't find it.
I scrolled through all 21 pages and moused over every link to be sure I wasn't missing it.
I found Xpdf 3.02 here by wellswang, is this it?
