在C＃下不存在D3DXSaveSurfaceToFile（）！ [英] D3DXSaveSurfaceToFile() does not exist under C#!

问题描述

这真的开始让我感到沮丧。有人请证明我错了。


这是DX 9 sdk中函数的链接。
http://msdn.microsoft .com / library / de ... facetofile.asp


以下dll'在我的程序中被引用。

Microsoft.DirectX .dll

Microsoft.DirectX.Direct3D.dll

Microsoft.DirectX.Direct3DX.dll


代码：


使用Microsoft.DirectX;

使用Microsoft.DirectX.Direct3D;

..

..

//这里试图调用D3DXSaveSurfaceToFile

//参数错误但不是问题

D3DXSaveSurfaceToFile（）;


我得到的错误：MainFrom中不存在该名称...... bla bla


换句话说，我无法找到该功能。在哪里？

请帮助。


如果有帮助，这里是我想要做的链接。链接在C ++中唯一的

问题。

您必须使用interop来调用dll中的API方法。网上有大量的例子，我建议你检查google或codeproject。

想法是将dll中的条目（你需要的）映射到一个C＃

等价的方法，并调用映射的方法。

感谢您的帮助。

您必须从API中映射您使用的功能，其中包括

参数映射和返回值（也称为编组）。在API中使用

应该映射，这涉及内存布局和打包

规范。问题是你使用的dll不是为.NET编写的

或C＃（如果我正确读取）但是对于C / C ++。那么如果你想使用dll，那么除了使用.NET中的互操作性功能之外别无选择。

网上的文章，例如google，或 http：//www.codeproject .com 或
http://www.codeguru.com 有很多。


否则，试着找一个.NET组件这是一样的。我没有直接使用DirectX的

程序，所以我无法帮助你。

This is really starting to piss me off. Someone please prove me wrong.

Here is a link to the function in DX 9 sdk.
http://msdn.microsoft.com/library/de...facetofile.asp

Following dll''s are referenced in my program.
Microsoft.DirectX.dll
Microsoft.DirectX.Direct3D.dll
Microsoft.DirectX.Direct3DX.dll

The code:

using Microsoft.DirectX;
using Microsoft.DirectX.Direct3D;
..
..
//here trying to call D3DXSaveSurfaceToFile
//the parameters are wrong but thats not the problem
D3DXSaveSurfaceToFile();

The eror I get: "The name does not exist in MainFrom..." bla bla

In other words, I cannot locate the function. Where is it?
Please help.

If it helps, here is the link to what I am trying to do. The only
problem the link is in C++.

I''m sorry if I am missing something, but how do I know the C# equivalent
method? The only documentation of the method that I found is in C++.

The following is from the header file d3dx9tex.h, which is part of dx 9 sdk.

//----------------------------------------------------------------------------
// D3DXSaveSurfaceToFile:
// ----------------------
// Save a surface to a image file.
//
// Parameters:
// pDestFile
// File name of the destination file
// DestFormat
// D3DXIMAGE_FILEFORMAT specifying file format to use when saving.
// pSrcSurface
// Source surface, containing the image to be saved
// pSrcPalette
// Source palette of 256 colors, or NULL
// pSrcRect
// Source rectangle, or NULL for the entire image
//
//----------------------------------------------------------------------------

HRESULT WINAPI
D3DXSaveSurfaceToFileA(
LPCSTR pDestFile,
D3DXIMAGE_FILEFORMAT DestFormat,
LPDIRECT3DSURFACE9 pSrcSurface,
CONST PALETTEENTRY* pSrcPalette,
CONST RECT* pSrcRect);

HRESULT WINAPI
D3DXSaveSurfaceToFileW(
LPCWSTR pDestFile,
D3DXIMAGE_FILEFORMAT DestFormat,
LPDIRECT3DSURFACE9 pSrcSurface,
CONST PALETTEENTRY* pSrcPalette,
CONST RECT* pSrcRect);

#ifdef UNICODE
#define D3DXSaveSurfaceToFile D3DXSaveSurfaceToFileW
#else
#define D3DXSaveSurfaceToFile D3DXSaveSurfaceToFileA
#endif

-------------------------------------------------------------------------------

I would really apreciate it if you could help me get this function to work.

This is what I have so far.

[DllImport("Direct3DX.dll",EntryPoint="D3DXSaveSurf aceToFile")]
//I have no clue about the last two arguments so I left them out, they
//can be null, but I still need a C# equivalent.
//ImageFileFormat I basically guessed, so dont know if thats the right
//equivalent to D3DXIMAGE_FILEFORMAT
//I''m pretty sure that HRESULT in C# is Int32
//and LPCSTR is String
static extern Int32 D3DXSaveSurfaceToFile(String
pDestFile,ImageFileFormat DestFormat,Surface pSrcSurface);

//and then use it as
D3DXSaveSurfaceToFile("2.bmp",ImageFileFormat.Bmp, mySurface);

The program doesn''t crash or anything, but 2.bmp is not there. =(

Also, I tried running "tdump Direct3DX.dll" and the funtions were not
listed.

Thank you for the help.

Thank you for the help.

You will have to map the functions you use from the API, which includes
mapping of parameters & return values (aka marshalling). Also structs used
in the API should be mapped, which involves memory-layout and packing
specifications. The problem is that the dll you use is not written for .NET
or C# (If I Read Correctly) but for C/C++. Then there is no choice but to
use interoperability features in .NET if you want to use the dll. Check for
articles on the net, e.g. google, or http://www.codeproject.com or
http://www.codeguru.com. There are plenty.

Otherwise, try to find a .NET assembly which does the same. I don''t make
programs that use DirectX directly, so I can''t help you with that.
