set default zoom for pdf

[bcbirkhauser]

Is there a way to set the default zoom for the pdf? I've tried adding pdf open params to the url, but that has no effect. I need to set the default zoom to be page-width.

This can be implemented in webodf/programs/viewer/viewer.js
The url would be parsed there and it would look like this:
src = "/ViewerJS/?zoom=page-width#presentation.odp"
The string value of the zoom option would be passed to the viewer member kDefaultScale.
This would happen in this.initialize in viewer.js.
Parsing the query string in the url can be done with:

var query = {};
window.location.search.substr(1).split('&').forEach(function (q) {
var s = q.split('=',2);
query[s[0]] = s[1];
});
kDefaultScale = query['zoom'] || 'auto';

Today ViewerJS 0..5.5 got releaesed, and it comes with webodf/WebODF#859 integrated, which picked up the proposal given above by @vandenoever .

So one can now control the initial zoom by passing a zoom argument to ViewerJS, e.g. like /ViewerJS/index.html?zoom=page-width#pages.pdf.

Thus closing this issue now.
