Im having trouble with displaying any bitmaps that are not ^2 x ^2. I want to display a 24x24 bitmap but something is going wrong and i have a black bar across the bottom. The bitmap looks fine in LView and paint but try as I might I haven''t been able to figure why this happens. Could it be my bitmap loader?

    
LPDIRECTDRAWSURFACE7 LoadBitmap(char *filename, int palette)
{
	BitmapFile				bitmap;
	FILE					*filepointer;
	UCHAR					*surfacebuffer;
	LPDIRECTDRAWSURFACE7	bitmapsurface;
	
	if(!(filepointer = fopen(filename, "r")))
		ErrorBox("Could not open bitmap file");
	
	if(!(fread(&bitmap.bitmapfileheader, sizeof(BITMAPFILEHEADER), 1, filepointer)))
		ErrorBox("Could not read bitmapfileheader");
	
	if(bitmap.bitmapfileheader.bfType != 0x4D42)
		ErrorBox("File is not a bitmap file");
	
	if(!(fread(&bitmap.bitmapinfoheader, sizeof(BITMAPINFOHEADER), 1, filepointer)))
		ErrorBox("Could not read bitmapinfoheader");

	if(bitmap.bitmapinfoheader.biBitCount == 8)
		if(!(fread(&bitmap.palette, sizeof(PALETTEENTRY), 256, filepointer)))
			ErrorBox("Could not read palette");

	if(!(bitmap.buffer = new BYTE[bitmap.bitmapinfoheader.biSizeImage]))
		ErrorBox("Could not allocate memory");
	
	if(!(fread(bitmap.buffer, sizeof(BYTE), bitmap.bitmapinfoheader.biSizeImage, filepointer)))
		ErrorBox("Could not read bitmap image data");

	bitmapsurface = CreateOffScreenPlain(bitmap.bitmapinfoheader.biWidth, bitmap.bitmapinfoheader.biHeight);

	bitmapsurface->Lock(NULL, &ddsd, DDLOCK_SURFACEMEMORYPTR | DDLOCK_WAIT, NULL);

	surfacebuffer = (UCHAR *)ddsd.lpSurface;
	for(int index=0; index < bitmap.bitmapinfoheader.biHeight; index++)
		memcpy(&surfacebuffer[index * bitmap.bitmapinfoheader.biWidth],
			   &bitmap.buffer[(bitmap.bitmapinfoheader.biHeight - (index + 1)) * bitmap.bitmapinfoheader.biWidth],
			   bitmap.bitmapinfoheader.biWidth + ddsd.lPitch);

	bitmapsurface->Unlock(NULL);

	delete [] bitmap.buffer;
	
	if(fclose(filepointer) != 0)
		ErrorBox("Could not close bitmap file");

	if(palette == YES)
		AttachPalette(bitmap.palette);
	
	return(bitmapsurface);
