可以.BMP文件存储在HTA(HTML/VBScript)中



我在FireFox书签的备份中注意到,每个条目左侧显示的图标在a标记中作为字符流。例如:

ICON="data:image/png;base64,iVBOR[删除数据以缩短示例]rkJggg==">

我有3个BMP文件(2 are 4x20 (249 bytes) and 1 is 102x82 (24.7 KB)),我想隐藏在我的HTML应用程序中,这样它们就不会丢失。

较大的一个在样式标签中出现3次,如下所示(显示1次(:

<style type="text/css">
#frmMainBody
  {background:grey; background-image:url('Background.bmp'); margin:0;
   padding:0; font:normal 10pt Microsoft Sans Serif;}
</style>

另外两个出现在VBScript子例程中,如下所示:

Sub Button_Glow
  ' Highlights a button when the cursor hovers over it.
  With Window.Event.srcElement.Style
    If .BackgroundColor <> "Lavender" Then
      .BackgroundColor = "Lavender"
      .BackgroundImage = "url(Glow.bmp)"
      .BackgroundPositionY = -2
      .BackgroundRepeat = "Repeat-X"
    End If
  End With
End Sub 'Button_Glow

这可能吗?

HTA是一种纯文本可编辑标记语言,您可以使用任何纯文本编辑器(如Notepad++(打开和编辑它。

您可以CAN通过将图像转换为base64,然后代替,将任何图像格式存储在HTML、CSS等中

<img src="mypath/myimage.bmp" />
<style type="text/css">
foo { background: url(mypath/myimage.bmp); }
</style>

你会放::

<img src="data:image/x-png;base64,iVBORw0KGgoAAAANS....." />
<style type="text/css">
foo { background: url(data:image/x-png;base64,iVBORw0KGgoAAAANS.....); }
</style>

为了让这对你来说更容易,你可以使用在线工具将图像转换成这种格式,比如这里的工具>>将任何图像转换成Base64字符串<lt。

如何将其应用于问题中的代码

使用其中一个工具(或编写自己的工具(,定位并将"Background.bmp"转换为base64,然后像这样修改您发布的第一块代码(也缩短以节省空间(

<style type="text/css">
#frmMainBody
  {background:grey; background-image:url(data:image/x-png;base64,iVBORw0KGgoAAAANS....); margin:0;
   padding:0; font:normal 10pt Microsoft Sans Serif;}
</style>

接下来,对于VBScript代码,定位并转换"Glow.bmp"(与上面的"Background.bmp"相同(,然后修改代码块,使其看起来像这个

Sub Button_Glow
  ' Highlights a button when the cursor hovers over it.
  With Window.Event.srcElement.Style
    If .BackgroundColor <> "Lavender" Then
      .BackgroundColor = "Lavender"
      .BackgroundImage = "data:image/x-png;base64,iVBORw0KGgoAAAANS....."
      .BackgroundPositionY = -2
      .BackgroundRepeat = "Repeat-X"
    End If
  End With
End Sub

左侧的图像被称为favicon,其默认大小为16x16并且应该在中。ICO格式(但也可以是其他格式(。

当你写关于隐藏一个。BMP图像,我想你想存储而不是隐藏收藏夹图标,所以它总是加载的,即使书签/用户离线。正确的

我不擅长vb,但你可以将文件或图像编码到base64(在带有base64_encode((函数的PHP中(,vb中应该有一个函数。您所要做的就是将图像文件(例如XXXXXX.png(中的内容或字符串保存为变量,并将其传递到base64编码函数中。

你也可以使用这种方法将图像直接保存到数据库中(我想…(,但你必须解码字符串才能使图像出现。(假设你在做这个。(-不要在家里尝试。它可能会杀死你的猫并烧毁你的房子:/

这可能会有所帮助-一个使用VBScript将图像文件编码为base64的HTA(代码改编自VBScript和VBScript中的base64编码字符串以打开对话框选择文件路径(。

您可以生成base64代码并将其用作图像的来源,例如:
