1、使用 C/C+进行图像处理 本系列仅针对 BMP 格式的图像 实现的 功能 包括读，存，二值化， 缩放 ， 反色 ， 均值滤波 ， 中值滤波 ， 增强 ， 腐蚀 ， 膨胀 功能 ： 缩放 （ 运行本程序需要参考“ 数字图像处理 1” ） /w 代表宽度 变为原来的 w 倍 ， h 代表高度变为原来的 h 倍 /本程序可以正常放大； 但是当 w、 h 小于 1 时，可以实现缩小，但会出现异常 ，如果你发/现了 错误的地方，还请私信我，我会进行改正。谢谢 RGBQUAD* suofang(RGBQUAD* dataOfBmp_src,DWORD width, DWORD height, float
2、 w, float h) DWORD nwidth = w*width; DWORD nheight = h*height; RGBQUAD* dataOfBmp_dst=NULL; dataOfBmp_dst = new RGBQUAD*nheight; for(DWORD n=0; n 0) float r1=dataOfBmp_srciijj.rgbRed;float r2=dataOfBmp_srciijj+1.rgbRed; float g1=dataOfBmp_srciijj.rgbGreen;float g2=dataOfBmp_srciijj+1.rgbGreen; float
3、 b1=dataOfBmp_srciijj.rgbBlue;float b2=dataOfBmp_srciijj+1.rgbBlue; dataOfBmp_dstij.rgbRed = (1.0-k)*r1+k*r2; dataOfBmp_dstij.rgbGreen = (1.0-k)*g1+k*g2; dataOfBmp_dstij.rgbBlue = (1.0-k)*b1+k*b2; continue; if(kmbnum; /将像素颜色数据（ RGBA）保存到数组中对应的位置 dataOfBmp_srcij.rgbRed = pRgbmixIndex.rgbRed; dataOfBmp
4、_srcij.rgbGreen = pRgbmixIndex.rgbGreen; dataOfBmp_srcij.rgbBlue = pRgbmixIndex.rgbBlue; dataOfBmp_srcij.rgbReserved = pRgbmixIndex.rgbReserved; if(bitInfoHead.biBitCount = 16) if(!bitInfoHead.biCompression) for( i=0;i3)+(pColorDatak5); dataOfBmp_srcij.rgbRed=(pColorDatak+13; dataOfBmp_srcij.rgbRese
5、rved = 0; if(bitInfoHead.biBitCount = 24 & !bitInfoHead.biCompression) for( i=0;iheight;i+) int k0 = (height-i-1)*l_width; for( j=0;jwidth;j+) k = k0+(j*3); dataOfBmp_srcij.rgbRed = pColorDatak+2; dataOfBmp_srcij.rgbGreen = pColorDatak+1; dataOfBmp_srcij.rgbBlue = pColorDatak; dataOfBmp_srcij.rgbRes

8、(bitInfoHead.biBitCount24 & pRgb) delete pRgb; for(i=0; iheight; i+) if(dataOfBmp_srci) delete dataOfBmp_srci; if(dataOfBmp_src) delete dataOfBmp_src; for(i=0; iheight; i+) if(dataOfBmp_dsti) delete dataOfBmp_dsti; if(dataOfBmp_dst) delete dataOfBmp_dst; for(i=0; iheight; i+) if(dataOfBmp_grayi) delete dataOfBmp_grayi; if(dataOfBmp_gray) delete dataOfBmp_gray; if(pColorData) delete pColorData;
