Description

This problem is probably really easy for someone with VC++ 6 experience.

I have an old program that I am trying to decipher (I am not a VC++6 programmer) so I am not sure exactly how the bitmap stuff works. But what I need to do is the following

1) Read as 32bit GrayScale or monochrome bitmap from a file;
2) Reduce it to 16 Bit;
3) Display it with the following function

So basically I need to get the reduced 16 bit data and placed in the UCHAR *ViewBuff like this

ShowCapturedPrint(0,0,640,480,ViewBuff );

See attached bitmap file

/******************************************************
// function: ShowCapturedPrint
// parameters: none
// return value: none
// purpose: show the last live print
/******************************************************/
void ShowCapturedPrint(short xoff, short yoff, short Width, short Height, UCHAR *ViewBuff)
{
HDC hDC;

short nx, ny;

hDC = GetDC(h_MainWindow);
Rectangle(hDC,0,0,n_ParentVideoWidth,n_ParentVideoHeight);
for(nx = xoff; nx<Width+xoff; nx++)
{
for(ny = yoff; ny<Height+yoff; ny++)
{
if(ViewBuff[nx + ny*Width] != 0)
SetPixel(hDC, nx, ny, RGB(0,0,0)); // offset the picture by the cropping values
}
}
ReleaseDC(h_MainWindow, hDC);
}
