**** dogfoot note ****

wxWidgets과 FreeImage의 조합이 필요하다면 아래의 소스를 분석해본다.

아래의 코드도 보고.

void MyFrame::Test(wxCommandEvent& event)
{
	if ( false == m_image.load("a.jpg") )
	{
		wxMessageBox(_T("can not load"), _T("warning"), wxOK, this);
		return;
	}
 
	m_image.convertTo32Bits();
 
 
	{
		int width = m_image.getWidth();
		int height = m_image.getHeight();
		int scanWidth = m_image.getScanWidth();
 
		// Create the wxBitmap object
		m_pBitmap = new wxBitmap(width, height, 32);
 
		typedef wxPixelData<wxBitmap, wxAlphaPixelFormat> PixelData;
		wxAlphaPixelData data(*m_pBitmap);
		data.UseAlpha();
 
		PixelData::Iterator p(data);
 
		// Iterate the image lines:
		for(int y = height-1; y >= 0; --y)
		{
		     PixelData::Iterator rowStart = p;
 
		     // Iterate the current line pixels:
		     BYTE* pLineData = m_image.getScanLine(y);
 
		     for(int x = 0; x < width; ++x, ++p, pLineData += 4)
		     {
		          p.Red() = pLineData[2];
		          p.Green() = pLineData[1];
		          p.Blue() = pLineData[0];
		          p.Alpha() = pLineData[3];
		     }
 
		     p = rowStart;
		     p.OffsetY(data, 1);
		}
	}
	wxClientDC dc(this);
	dc.DrawBitmap(*m_pBitmap, wxPoint(0,0));
}

아래는 FreeImage를 이용하여 이미지를 보여주는 예제이다.
