在html中,显示svg,<object>看起来要比<embed>更加合适,因为当svg尺寸过大时,<object>只会对其缩放,而<embed>会将图像裁剪掉
正所谓:既生瑜,何生亮。但是<object>是一个比<embed>更不正式的标签!
如果你的svg需要给更多的人看,那么使用<embed>是一个不错的选择!
很简单,我们可以从svg读出其width,height!
由于svg也是XML格式的,那么就容易多了!
<%@ Import NameSpace="System.XML" %> 别忘了导入相应的名称空间
方法如下:相应的函数的作用我就不详细说明了,.NET Framework中都有详细的说明
sub showSvgWindow(theSvgPath as string)
dim reader as xmlTextReader = Nothing
dim nodeAttribtion as new arrayList()
dim i,width,height as integer
reader = new xmlTextReader(server.MapPath(theSvgPath))
dim exp as exception
Try
While reader.Read()
If reader.NodeType = XmlNodeType.Element And reader.Name = "svg" Then
If reader.HasAttributes Then
For i = 0 to (reader.attributeCount-1)
reader.moveToAttribute(i)
If reader.Name = "width" Then
width = reader.Value
End If
If reader.Name = "height" Then
height = reader.Value
End If
Next
End If
Exit While
End If
End While
Catch exp
End Try
If CInt(width) < 50 Then
width = "50"
Else If CInt(height) < 50 Then
height = "50"
End If
svgWindow.Text = "<embed src=" & theSvgPath & " height=" & height & "px width=" & width & "px></embed>"
svgTitle.Text = request.QueryString("title")
end sub
