SetPreviewZoom

Description

Use this method to specify the Zoom to be used during print preview - this is view zooming, not printscaling.

Syntax

printing.SetPreviewZoom(lZoom, pagesX, pagesY)

Parameter	Description
lZoom	(Number) The Zoom scaling to use, either expressed as a percentage (e.g. 200 for double full size) or one of the following special values: Value Meaning -1 Zoom to show the full page width in the view. -2 Zoom to show the full page height in the view. -3 Zoom to show 2 full height pages in the view. 0 Zoom to show full height pages, layed out as described by the pagesX and pagesY parameters (requires the IE 7 style template). For the IE 6 and earlier style template, the default value is 75%. For IE 7 and later style templates, the default value is -2.
pagesX	[Optional, requires the IE 7 style template] (Number) Only used with the IE 7 style template when lZoom is 0. Specifies the number of pages to display across the view (columns).
pagesY	[Optional, requires the IE 7 style template] (Number) Only used with the IE 7 style template when lZoom is 0. Specifies the number of rows of pages to display.

Example

function startPreview() {
    var z, x=0, y=0;

    // if not IE 7 template
    if (document.getElementById("selectTemplate").selectedIndex != 1) { 
        var s = document.getElementById("selectZoom");
        z = s.options[s.selectedIndex].value;
    }
    else {
        var s = document.getElementById("selectZoom");
        var s1 = document.getElementById("selectPages");

        var o = parseInt(s1.options[s1.selectedIndex].value);

        switch (o) {
            case 0: // zoomed one page
                z = s.options[s.selectedIndex].value;
                break;
            case 2: // the rest are multi-page views.
                z = 0;
                x = 2;
                y = 1;
                break;
            case 3:
                z = 0;
                x = 3;
                y = 1;
                break;
            case 6:
                z = 0;
                x = 3;
                y = 2;
                break;
            case 12:
                z = 0;
                x = 4;
                y = 3;
                break;
        }
    }

    factory.printing.SetPreviewZoom(z, x, y);
    factory.printing.Preview();
