C++ (Cpp) Image2D::GetMaxMinNormalizationFactor Examples

Example #1

File: pngfile.cpp Project: jjdmol/LOFAR

void PngFile::Save(const Image2D &image, const ColorMap &colorMap) throw(IOException)
{
	long double normalizeFactor = image.GetMaxMinNormalizationFactor();
	
	png_bytep *row_pointers = RowPointers();
	
	for(unsigned long y=0;y<image.Height();++y) {
		for(unsigned long x=0;x<image.Width();++x) {
			int xa = x * PixelSize();
			row_pointers[y][xa]=colorMap.ValueToColorR(image.Value(x, y) * normalizeFactor);
			row_pointers[y][xa+1]=colorMap.ValueToColorG(image.Value(x, y) * normalizeFactor);
			row_pointers[y][xa+2]=colorMap.ValueToColorB(image.Value(x, y) * normalizeFactor);
			row_pointers[y][xa+3]=colorMap.ValueToColorA(image.Value(x, y) * normalizeFactor);
		}
	}
}
