var resultVar = instanceOfImGearIsisScanner.setTagRational(number(Integer),number(Integer),number(Integer),number(Integer),function);

Parameters

tagID

The ID of the tag.

numerator

The value to set the tag numerator to.

denominator

The value to set the tag denominator to.

index

The index to use, for tags that contain multiple values. If the tag contains only a single value, this must be 0.

callback

Callback which is called when the tag is set.

Return Value

The JavaScript code below demonstrates how to set the scanner ISIS X resolution tag to a rational value of 300/1. You can use the getTag method to get the tag type and list or range of supported values for a tag.

function setTagCallback(status) {
    if (status.get_status() !== ImageGear.Web.Isis.ImGearIsisStatus.Completed) {
        alert(status.get_statusMessage());
    }
}

scannerSession.get_scanner().setTagRational(ImageGear.Web.Isis.ImGearIsisTag.XResolution, 300, 1, 0, setTagCallback);

This is an asynchronous method.

To set the values of multiple tags, it is more efficient to use setAllTags.

The scanner must be set before calling this method.

For more information on ISIS tags, refer to the ISIS Tags topic.
