Hello, I keep trying to load a 8-bit bitmap and when I extract the values/color of a pixel at x, y I always get the wrong color from the palette. Does anyone know of a function, and/or site that will tell me how to do it correctly? My function is in my class here: (*note* this is a 8-bit bitmap for a height map - grayscale) #ifndef CXHEIGHTMAP_H #define CXHEIGHTMAP_H #include void SetError(char* String){ OutputDebugString( "ERROR: " ); OutputDebugString( String ); OutputDebugString( "\n" ); } class CXHeightMap { public: CXHeightMap(); ~CXHeightMap(); // Function public: int LoadMap( char* szPath ); // Variables public: BITMAPFILEHEADER bitmapfileheader; BITMAPINFOHEADER bitmapinfoheader; PALETTEENTRY palette[256]; BYTE *buffer; int nWidth, nHeight; }; //--------------------------------------------------------------- // //--------------------------------------------------------------- inline CXHeightMap::CXHeightMap() { for( int i = 0; i < 256; i++){ palette.peBlue = i; palette.peGreen = i; palette.peRed = i; palette.peFlags = PC_NOCOLLAPSE; } buffer = NULL; } //————————————————————— // //————————————————————— inline CXHeightMap::~CXHeightMap() { if(buffer) delete[] buffer; } //————————————————————— // //————————————————————— inline int CXHeightMap::LoadMap( char* szPath ) { if(lstrlen(szPath) <= 2){ SetError( "szPath <= 2" ); return 0; } int file_handle; OFSTRUCT file_data; if((file_handle = OpenFile( szPath, &file_data, OF_READ)) == -1){ SetError( "file_handle == -1"); return 0; } // load the bitmap file header _lread(file_handle, &bitmapfileheader, sizeof(BITMAPFILEHEADER)); // see if the image from the path is a bitmap file if( bitmapfileheader.bfType != 0x4D42 ){ SetError( szPath ); SetError( "Is not a bitmap!" ); _lclose(file_handle); return 0; } _lread(file_handle, &bitmapinfoheader, sizeof(BITMAPINFOHEADER)); _lseek(file_handle, -(int)(bitmapinfoheader.biSizeImage) , SEEK_END); if(bitmapinfoheader.biBitCount == 8){ if( buffer ) delete[] buffer; buffer = new BYTE[bitmapinfoheader.biSizeImage]; UINT nRead = 0; nRead = _lread(file_handle, buffer, bitmapinfoheader.biSizeImage); cout << "nRead = " << nRead << endl; } else{ SetError( "biBitCount != 8 bits" ); return 0; } nHeight = bitmapinfoheader.biHeight; nWidth = bitmapinfoheader.biWidth; _lclose(file_handle); return 1; } #endif </i> Edited by - David_Kay on October 23, 2001 8:36:38 PM Edited by - David_Kay on October 23, 2001 8:37:09 PM
