Convert custom bitmap to CBitmap/CImage bits format

[mesajflaviu]

I am open to give any information that I got about this member variable, but this is only from source code, is the only information source. I come back little bit later.

@VictorN: you helped me a lot in the past and I thank you. Even if you have enough time to answer me or not, from respect to you I'll try to explain as much as I could of what is about this variable:

The definition of this class is

	class CCustomBitmap
	{
	private:
		std::vector<float> data;
		int m_nWidth;
		int m_nHeight;
		int channels;

	public:
		CCustomBitmap()
			: m_nWidth(0),
			m_nHeight(0),
			channels(0) {}

		CCustomBitmap(int m_nWidth, int m_nHeight, int channels)
			: data(m_nWidth * m_nHeight * channels),
			m_nWidth(m_nWidth),
			m_nHeight(m_nHeight),
			channels(channels) {}

		const float& operator [](size_t i) const { return data[i]; }
		float& operator [](size_t i) { return data[i]; }

		int getChannels() const { return channels; }
	....
	}

channels is declared here but seem not be involved into serializing method:

	CCustomBitmap loadImage(const std::string& filename)
	{
		std::ifstream file(filename, std::ios::binary);
		int C = 3;
		int nHeight, nWidth;
		file >> nWidth >> nHeight;

		float scale;
		file >> scale;			// I noticed that scale is -1
		scale = fabs(scale);	        // so here scale is 1.0

		CCustomBitmap image(nWidth, nHeight, C);

		for (int h = 0; h < nHeight; ++h)
		{
			for (int w = 0; w < nWidth; ++w)
			{
				for (int c = 0; c < C; ++c)
				{
					float x;
					file.read((char*)&x, sizeof(float));
					image[((nHeight - 1 - h) * nWidth + w) * C + c] = x * scale;  // scale is 1, so image[((nHeight - 1 - h) * nWidth + w) * C + c] = x is enough here
				}
			}
		}

		return image;
	}

but CCustomBitmap:: data is populated on 3 dimension array somehow ... the problem is that I don't know how to populate this CCustomBitmap:: data which has 3 d array from CImage, which has a 2 dimension array GetPixel(w, h). I don't have any extra-information about that variable, channels.

Because I am stuck here, any opinion/hint/solution will be very valuable !!! Thank you.
