I have been asked several time about quality meter algorithm, in order to understand how it works. Here is Java code for it:

Code:
	public static ArrayList init(
				Color topColor,
				Color middleColor,
				Color bottomColor,
				ArrayList qualityMeterFormats,
				int imageWidth,
				int imageHeight)
	{
		ArrayList result = new ArrayList();
		for (int i = 0; i < qualityMeterFormats.size(); i++)
		{
			QualityMeterFormat qualityMeterFormat = (QualityMeterFormat)qualityMeterFormats.get(i);
			int formatWidth = qualityMeterFormat._width;
			int formatHeight = qualityMeterFormat._height;
			if (formatWidth < formatHeight)
			{
				int thirdGlass = formatWidth;
				formatWidth = formatHeight;
				formatHeight = thirdGlass;
			}
			if (imageWidth < imageHeight)
			{
				int thirdGlass = imageWidth;
				imageWidth = imageHeight;
				imageHeight = thirdGlass; 
			}
			Color color;
			if (   imageWidth >= formatWidth 
				&& imageHeight >= formatHeight)
			{
				color = bottomColor;
			}
			else
				if (   Math.round((double)imageWidth * qualityMeterFormat._maxRatio) >= formatWidth
					&& Math.round((double)imageHeight * qualityMeterFormat._maxRatio) >= formatHeight)
				{
					color = middleColor;
				}
				else
				{
					color = topColor;
				}
			result.add(color);
		}
		return result;
	}
