本文详细介绍了如何利用DirectX库从内存中加载图片数据，包括解析常见的图像文件格式，设置纹理对象，以及在3D场景中应用这些纹理的步骤。通过实例代码，演示了内存中图像数据到DirectX渲染过程的关键转换操作。
#include <fstream>
using namespace std;
//方法一
ifstream inFile(filename, ios::binary);
inFile.seekg(0, ios::end);
int len = inFile.tellg();
inFile.close();
BYTE* encodeBuffer = new BYTE[len];
FILE *fp = fopen(filename.c_str(), "rb");
len = fread(encodeBuffer, 1, len, fp );
hResult = D3DXLoadSurfaceFromFileInMemory(surface, NULL, NULL, (BYTE*)encodeBuffer, len,NULL, D3DX_FILTER_NONE, 0, &imageInfo);
delete []encodeBuffer;
if (FAILED(hResult))
