使用Flex3在TLF中的图像顶部有太多空间

Question

在flex3中将图像插入TLF时，我发现TLF中的图像显示在方形区域中。所以图像顶部有一些空间。有关此问题，请参阅附图。

如何删除此空间？我尝试以下方法，但它不起作用！

var graphic_element:InlineGraphicElement = IEditManager(activeFlow.interactionManager).insertInlineGraphic(foreignElementUrl, width, height, "none");

graphic_element.paddingTop = 0;
graphic_element.paddingBottom = 0;
graphic_element.paddingRight = 0;
graphic_element.paddingLeft = 0; 
IEditManager(activeFlow.interactionManager).applyParagraphFormat(graphic_element);

Answer 1

也许这个？

inlineGraphicElement.textDecoration = null;
inlineGraphicElement.alignmentBaseline = TextBaseline.ASCENT;
inlineGraphicElement.lineHeight = "100%";

Answer 2

如果您从HTML源创建textFlow，则以下代码非常有用。它将校正显示文本流中的每个图像。

static private function _InlineGraphicElementCorrection(children:Array):void
{
    var numChildren:int = children.length;
    for (var i:int=0; i<numChildren; i++)
    {
        if( children[i].hasOwnProperty('mxmlChildren') )
            _InlineGraphicElementCorrection(children[i].mxmlChildren);
        if( !(children[i] is InlineGraphicElement) )
            continue;

        var graphicElement : InlineGraphicElement = children[i];
        graphicElement.textDecoration = null;
        graphicElement.alignmentBaseline = TextBaseline.ASCENT;
        graphicElement.lineHeight = "100%";
    }
}

static public function importHtmlToFlow(html:String):TextFlow
{
    var flow : TextFlow = TextConverter.importToFlow(html.replace(/[\r\n]/ig, ""), TextConverter.TEXT_FIELD_HTML_FORMAT);
    _InlineGraphicElementCorrection(flow.mxmlChildren);
    return flow
}
