Book -MegaZine3 页码，17/20Important: this disables all page interactivity, because of how the double click event in Flash works (does not allow interactivity with child elements of the element using the double click event).■See also:zoommaxscalezoominit ■Type:Number■Default:autoDetermines the initial zoom level for the book. If this is not set, liquid scaling kicks in and adjusts the scale accordingly. If set, this is the scaling used for the pages when the book is loaded (will be clamped to the minimum and maximum scaling, though).■See also:zoommaxscale, zoomminscalezoomliquidscaling ■Type:Boolean■Default:trueThis setting can be used to completely disable liquid scaling. Normally, liquid scaling is active initially, i.e. the book size adjusts to the available space. As soon as the user manually zooms in or out, liquid scaling is temporarily disabled, until the user zooms to the zoom level that would currently be used were liquid scaling active (zoom snaps to that value, also see book@zoomsnap). When this is set to false, liquid scaling will never kick in.zoomliquidsnap ■Type:Boolean■Default:falsePer default, liquid scaling will always scale the book to exactly fit into the available area. In some use-cases this might not be ideal, e.g. if the page content should only be displayed at certain zoom levels, for better visual quality. In these cases, set this attribute to true, which will make liquid scaling use the levels set in the zoomsnapattribute.zoommaxscale ■Type:Number■Default:1■Aliases:maxscaleDetermines the largest size to which to upscale the pages, as a percentage value. E.g. if set to 1.5the book can get larger to completely fit into the available space until it's at 150% of its original size. If minscale != maxscalethen Liquid Scalingis enabled.zoomminscale ■Type:Number■Default:1■Aliases:minscalehttp://www.megazine3.de/doc/Book 2013/9/3
