如何使用 Google Earth API 进行彩色屏幕截图？

Question

我正在 Excel VBA 中使用 Google Earth API。屏幕截图是黑白的，而不是彩色的。请建议我哪里做错了？

Dim ge As earthlib.ApplicationGE

Set ge = New ApplicationGE

Dim kmlString As Variant

kmlString = "C:\temp\test.kmz"

ge.OpenKmlFile (kmlString, 1)

Dim tPlace As earthlib.FeatureGE

Set tPlace = ge.GetTemporaryPlaces

Dim fldrPath As String, jpgName as String

fldrPath = "C:\temp\"

jpgName = fldrPath & "outJpg1.JPG"

ge.SaveScreenShot (jpgName, 100)

Answer 1

我在本文档中找到的评论表明这是设计使然。不过，我还没有找到任何建议该做什么的信息。

/// \brief Takes low quality black and white screen shot
/// of the current camera view.
///
/// This image is not meant to  be used for rapid capture and degrades
/// in quality if used frequently.
///
/// \param fileName Full path JPG filename of output screen shot.
/// \param quality Quality factor of output image. Lowest quality is
/// \c 0 and highest quality is \c 100. Input quality is always clamped
/// to (\c 0, \c 100) inclusive.
///
/// \retval S_OK Successfully saved screen shot.
/// \retval (other) Appropriate error code.
[id(5), helpstring("method SaveScreenShot")]
HRESULT SaveScreenShot([in] BSTR fileName, [in] long quality);
