autoBaseline	The auto baseline of the selected text.

Examples

The following example demonstrates Selection.setAutoBaseline in a practical document-editing workflow. It sets values specifying automatic sub- or superscripted text. When using automatic sub- and superscript the font is scaled and moved above or below the baseline with values defined through the font itself. Automatic sub- and superscript can be combined with a user-defined baseline which can be set with the Baseline property.

function onTxError(error) {
    console.error("TX Text Control error:", error.msg);
    error.handled = true;
}

TXTextControl.selection.setAutoBaseline(
    TXTextControl.AutoBaseline.Superscript,
    function() {
        console.log("set auto baseline completed.");
    },
    onTxError
);
