如何使用 HTML 应用程序只显示居中图像?

How to use HTML application to display only centered image?

我正在使用 hta 文件作为初始屏幕,hta 文件打开的图像称为 "Loading1.png",大小为 478 x 50。在 hta 文件中设置 window 大小和位置时, 图片显示有白色边框并且偏离中心。

我的代码可能有什么问题?

<html>
    <hta:application id="oHTA"
        border="none"
        caption="no"
        contextmenu="no"
        innerborder="no"
        scroll="no"
        showintaskbar="no"
    />
    <script language="VBScript">
        Sub Window_OnLoad
            'Resize and position the window
            width = 478 : height = 50
            window.resizeTo width, height
            window.moveTo screen.availWidth - width, screen.availHeight - height

        End Sub
    </script>
<body>
    <table border=0 width="100%" height="100%">
        <tr>
            <td align="center" valign="middle">
                <img src="Loading1.png"/>
            </td>
        </tr>
    </table>
</body>
</html>

我只想在屏幕中央显示我的图像 "Loading1.png",没有边框或其他任何东西。

Loading1.png 图片属性:

HTA应用(注意精细平衡±1像素):

<html>
    <HTA:APPLICATION ID = "oHTA"
        BORDER          = "none"
        BORDERSTYLE     = "normal"
        CAPTION         = "no"
        CONTEXTMENU     = "no"
        SYSMENU         = "no"
        NAVIGABLE       = "no"
        INNERBORDER     = "no"
        SCROLL          = "no"
        SELECTION       = "no"
        SINGLEINSTANCE  = "yes"
        WINDOWSTATE     = "normal"
        SHOWINTASKBAR   = "no"
    />
<head>
  <meta http-equiv="x-ua-compatible" content="ie=9">

  <style type="text/css">
    body {
        background-color: red;  /*  ↓↓↓ merely for contrast ↓↓↓  */
        border-color:     red;  /*  ↑↑↑ merely for contrast ↑↑↑  */
        margin-top:      -1px;
        margin-left:     -1px;
        margin-bottom:   -1px;
        margin-right:    -1px;
    }
  </style>

  <script language="VBScript">
      Option Explicit
      Dim width, height
      width  = 478 -1                 '''  
      height =  50 -1                 ''' 
      Sub window_onload()
          CenterWindow width, height
      End Sub
      Sub CenterWindow( widthX, heightY )
          self.ResizeTo widthX, heightY 
          self.MoveTo (screen.availWidth - widthX)/2, (screen.availHeight - heightY)/2
      End Sub
  </script>
</head>

<body>
  <img src="Loading1.png"/>
</body>
</html>
