以原始分辨率导出图片Excel VBA
此解决scheme： 导出图片Excel VBA
工作得很好，但它使用的图表方法被调整到表格中的图像来“截图”（在我的情况下，甚至包括表格边框），而不是实际导出图像本身。
当我通过将excel表格转换为html文件来获取图像时，他们甚至可以在文件夹中获得更好的分辨率。
有没有办法让自己的图像，他们的原始分辨率，而不是使用VBA（显然，我不只是需要的图片，否则我会满足于HTML转换方法）？
我的意思是可以在这里看到： http : //i.imgur.com/OUX9Iji.png左边的图片是我使用html转换方法得到的，右边的图片是我使用图表方法得到的。 正如你所看到的图表方法只是在Excel表格中截图，我需要它得到像左边的原始图片。
由于较新的文件types.xlsm和.xlsx实际上是一个zip文件，因此可以让工作簿保存其自身的副本，并将扩展名从.xlsm更改为.zip。 从那里，它可以查看zip的xl / media文件夹，并将包含元数据等的实际图像文件复制出来。
对于我的目的，因为它改变了图像文件名（而不是文件types）的zip内，我正在如何更具体地重新命名图像文件基于工作簿内容（即，他们在工作簿中的位置）为用户而出。
但是，是的，截图几乎没有真正的文件，这种方法做到了。 这个小组花了我相当多的时间来写，但我相信会被很多人使用！

End Sub
我把副本移到它自己的子节点上，以节省我如何过滤文件types的空间，而不是最好的方式，但工程
Private Sub CopyFiles(strFromPath As String, strToPath As String, FileExt As String) 'As function to get multiple filetypes Dim FSO As Object If Right(strFromPath, 1) <> "\" Then strFromPath = strFromPath & "\" On Error Resume Next Set FSO = CreateObject("scripting.filesystemobject") FSO.MoveFile Source:=strFromPath & FileExt, Destination:=strToPath Set FSO = Nothing On Error GoTo 0 End Sub
我发现这个稳定的function在线来select一个目标文件夹，实际上很难find一个好的固体。
