CADImage from CADImage to BMP

[Javier]

I want to know how I can save my .PLT file into BMP format in C#.

I tried with this but it does not work.[xx(]

Code: Select all

private void btnConvert_Click(object sender, System.EventArgs e)
		{
			float AbsWidht=0, AbsHeight=0;
			CADDraw CrDraw= new CADDraw();
			FRect CrDraw1= new FRect();
			long r=0;
			double K= 0;

			DLLWin32Import.GetBoxCAD(DLLWin32Import.CADFile, AbsWidht, AbsHeight);
			DLLWin32Import.GetClientRect(DLLWin32Import.CADFile, ref CrDraw.R);
			if (AbsWidht==0)
				K= 1;
			else
				K= AbsHeight/ AbsWidht;
			//DLLWin32Import.GetExtentsCAD(DLLWin32Import.CADFile, ref CrDraw1);
			CrDraw.Size= Marshal.SizeOf(CrDraw);
			CrDraw.R.Top= 0;
			CrDraw.R.Left= 0;
			
			CrDraw.R.Right= CrDraw.R.Right * 100 / 100;
			CrDraw.R.Bottom= Convert.ToInt32(((double)(CrDraw.R.Right * K)));
			CrDraw.R.Bottom= CrDraw.R.Bottom * 100 / 100;
			CrDraw.DrawMode= 0;
			
			IntPtr hImagen= DLLWin32Import.DrawCADtoBitmap(DLLWin32Import.CADFile, ref CrDraw);
			long Size = DLLWin32Import.GlobalSize(hImagen);
			
            IntPtr P = DLLWin32Import.GlobalLock(hImagen);
            IntPtr FHnd = DLLWin32Import.CreateFile("c:\\ejemplo.bmp", GENERIC_WRITE, FILE_SHARE_READ, 0, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, IntPtr.Zero);
			DLLWin32Import.WriteFile (FHnd,ref P, Size,ref r, 0);
            DLLWin32Import.CloseHandle( FHnd);
            DLLWin32Import.GlobalUnlock( hImagen);
            DLLWin32Import.GlobalFree( hImagen);
}
