var simg = soImage();
simg.load("C:\Users\popdes\Desktop\f083.png")

winform.picturebox2.image = simg.getBytes("*.bmp")
//垂直翻转, 不执行这个会导致图像上下反的
simg.flip()
var addr = tonumber(raw.toPointer(simg.getBytes("*.bmp")));
var Image = HOperatorSetX.GenImage1( "byte" , simg.getWidth() , simg.getHeight() , addr );
var WindowHandle = HOperatorSetX.OpenWindow( 0 , 0 , winform.picturebox.width , winform.picturebox.height , winform.picturebox.hwnd , "visible", "" );
HOperatorSetX.DispObj( Image , WindowHandle );
winform.show();
win.loopMessage();
return winform;先记录到这里, 明显是有问题的, 正常情况下, 窗口应该两个图像显示的一致, 但是这个显示明显左右分离了

halcon图像变量转普通bitmap图像
代码如下,目前还有问题, 没实现成功, 以后有时间继续研究, 先放一边
var PointerRed , PointerGreen , PointerBlue , Type , Width , Height = HOperatorSetX.GetImagePointer3( Image );
console.varDump(PointerRed)
var PRed = raw.buffer(raw.tostring(topointer(PointerRed)))
var PGreen = raw.buffer(raw.tostring(topointer(PointerGreen)))
var PBlue= raw.buffer(raw.tostring(topointer(PointerBlue)))
console.log(Type , Width , Height)
var bmp5 = gdip.bitmap(Height , Width);
//获取位图数据
var bmpdata = bmp5.lockData32(,0x22009/*_PixelFormat32bppRGB*/);
var bptr = bmpdata.Scan0;
for(i=1;Width*Height;1){
bptr[(i-1)*4+1]=PBlue[i];
bptr[(i-1)*4+2]=PGreen[i];
bptr[(i-1)*4+3]=PRed[i];
bptr[(i-1)*4+4]=255;
}
bmp5.unlockData(bmpdata);
winform.plus.background = bmp5;目前还只是黑色一片.......

上面实现的方式有点问题, 去网上搜了下
参考网址里面的写法https://blog.csdn.net/bingbingxie1/article/details/83344704
实现了 bitmap变量转为 halcon变量
//bitmap变量转为 halcon变量 var bmp2halconPtr = function(bmpPath){ //从文件创建位图 var bmp = gdip.bitmap(bmpPath); //获取位图数据 var bmpdata = bmp.lockData32(,0x30803/*_PixelFormat8bppIndexed*/); var dataBlue = raw.buffer(bmp.width*bmp.height) var ptrdata = tonumber(raw.toPointer(dataBlue)); for(i=0;bmp.height-1;1){ ::CopyMemory(topointer((ptrdata+bmp.width*i)),topointer(tonumber(raw.toPointer(bmpdata.Scan0))+bmpdata.Stride*i),bmp.width); } bmp.unlockData(bmpdata); return ptrdata,bmp.width,bmp.height; } var ptrdata,宽,高 = bmp2halconPtr("C:\Users\popdes\Desktop\f083.png") var Image2 = HOperatorSetX.GenImage1( "byte" , 宽 , 高 , ptrdata ); var WindowHandle2 = HOperatorSetX.OpenWindow( 0 , 0 , winform.picturebox3.width , winform.picturebox3.height , winform.picturebox3.hwnd , "visible", "" ); HOperatorSetX.SetPart( WindowHandle2 , 0 , 0 , 高-1 , 宽-1 ); HOperatorSetX.DispObj( Image2 , WindowHandle2 );
