IMAGE FILTERS - RANGES GROUP

The Zoomify Image Viewer included in the Enterprise edition supports the ability to apply image filters to any Zoomify Image. This example demonstrates the image filters in the group labeled 'Ranges', which is implemented using the HTML parameter setting zImageFiltersVisible=ranges. These include the filters requiring dual slider buttons to specify a desired range within a permitted range. These are supported for each color channel.

The constraining effect of these sliders can be most easily seen by sliding any of the sliders fully to the left or right to set all pixel values for that channel to the minimum or maximum allowed. Or, slide all three sliders to the far left to achieve a completely black display, fully to the right for a completely white display.

Filters can be enabled or disabled using additional HTML parameters - either in conjunction with a group value or individually. See the example '85-ImageFilters-All' to view all of the image filters at once and find additional information in the Parameter List document in the Documentation folder of the product.
