- animationTime - The amount of time in seconds that animations should
last. Default is 1.5.
- blendTime - The amount of time in seconds that new tiles take to
blend from transparent to opaque. Default is 0.5.
- alwaysBlend - Whether tiles should always blend in and out, not
just when they're first loaded. Default is false.
- autoHideControls - Whether controls should get automatically hidden
when the user's mouse is off the viewer and the image has stopped animating. Default
is true.
- immediateRender - Whether the most appropriate tiles should always
be rendered first, before any lower-res tiles are rendered. This loses the "sharpening"
effect and instead creates a very visible "tiling" effect. Default is false.
- minZoomDimension - The minimum size (in screen pixels) of either
dimension that can result from zooming out. Default is 16.
- maxZoomPixelRatio - The maximum pixel ratio (screen pixel to content
pixel) that can result from zooming in. Default is 4.
- visibilityRatio - The minimum portion of the viewport that must
show visible content in both dimensions. Default is 0.1.
- springStiffness - Determines how sharply the springs used for animations
move. Default is 5.0.
- imageLoaderLimit - The maximum number of concurrent image downloads
that can be performed by each viewer. Default is 2.
- clickTimeThreshold - The maximum number of milliseconds that can
pass between a mousedown and a mouseup for the action to still be considered a "quick"
click. Default is 200.
- clickDistThreshold - The maximum number of pixels the mouse can
move between a mousedown and a mouseup for the action to still be considered a "quick"
click. Default is 5.
- zoomPerClick - The factor by which images should zoom when clicked
on. Default is 2.
- zoomPerSecond - The factor by which images should zoom over each
second when the zoom buttons are held down. Default is 2.
- sourceUrl - The path for all UI images. This can be absolute or
relative. If relative, it must be relative to the HTML page. A change to this value
will only affect new viewers. Default is "img/".
- showNavigationControl - Whether navigation buttons should be shown.
