hbitmap_在图片控件中显示传输的HBITMAP_由CreateCompatibleBitmap创建的HBITMAP是黑白的 - 腾讯云开发者社区

Gdiplus::Bitmap转HBITMAP，直接上代码 LPBYTE pBmpBits = NULL; BITMAPINFO bimpi = {0}; bimpi.bmiHeader.biSize...bimpi.bmiHeader.biBitCount = 32; bimpi.bmiHeader.biCompression = BI_RGB; bimpi.bmiHeader.biSizeImage = nCW * nCH*4; HBITMAP...这样HBITMAP里面就是Bitmap的图像数据了。对于HBITMAP转Gdiplus::Bitmap，原本写了代码但是没有保留，就不上代码了。简单说下，其实就是上面的过程反过来了。...1.通过GetBitmapBits()函数获取到HBITMAP的ARGB数据，然后通过 Gdiplus::BitmapData bitmapData; Gdiplus::Bitmap dstBmp(nCW
