C++，实现图像的翻转和变色

C++，实现图像的翻转和变色，实践周纪念一下
主要上下左右，180度翻转，和其他变色
需要用到头文件 atlimage.h，类CImage，COLORREF
编译器：VS，安装ATL for 142生成工具
字符集设置为宽字符，或者利用LPCTSTR直接定义，不过 dev-C++可以不用考虑定义LPCTSTR，也无需设置，直接使用，不过就是不能用atlimage.h这个头文件是了，基本的文件输入输出没问题
修改的图文件都是jpg格式

左右颠倒

void reverseRGB(COLORREF& c1, COLORREF& c2)//左右颠倒上下颠倒
{
	c1 = RGB(GetRValue(c2), GetGValue(c2), GetBValue(c2));
	c2 = RGB(GetRValue(c1) , GetGValue(c1) , GetBValue(c1));
}
void Work_3()//实现左右颠倒
{
	LPCTSTR regionFilePath = _T("2a.jpg");//源文件路径
	LPCTSTR finalFilePath = _T("2d.jpg");//目标图像路径
	CImage regionmage;
	regionmage.Load(regionFilePath);
	int width = regionmage.GetWidth();
	int height = regionmage.GetHeight();
	for (int x = 0; x < width/2; x++)
	{
		for (int y = 0; y < height; y++)
		{
			COLORREF c1 = regionmage.GetPixel(x, y);
			COLORREF c2 = regionmage.GetPixel(width-x-1, y);
			reverseRGB(c1, c2);
			regionmage.SetPixel(x, y, c1);
			regionmage.SetPixel(width - x - 1,y, c2);
		}
	}
	regionmage.Save(finalFilePath);
}

上下颠倒

void reverseRGB(COLORREF& c1, COLORREF& c2)//左右颠倒上下颠倒
{
	c1 = RGB(GetRValue(c2), GetGValue(c2), GetBValue(c2));
	c2 = RGB(GetRValue(c1) , GetGValue(c1) , GetBValue(c1));
}
void Work_4()//实现上下颠倒
{
	LPCTSTR regionFilePath = _T("2a.jpg");//源文件路径
	LPCTSTR finalFilePath = _T("2e.jpg");//目标图像路径
	CImage regionmage;
	regionmage.Load(regionFilePath);
	int width = regionmage.GetWidth();
	int height = regionmage.GetHeight();
	for (int x = 0; x < width; x++)
	{
		for (int y = 0; y < height/2; y++)
		{
			COLORREF c1 = regionmage.GetPixel(x, y);
			COLORREF c2 = regionmage.GetPixel(x, height-y-1);
			reverseRGB(c1,c2);
			regionmage.SetPixel(x, y, c1);
			regionmage.SetPixel(x, height - y - 1, c2);
		}
	}
	regionmage.Save(finalFilePath);
}

180度顺势针翻转（请指正，有瑕疵）

void reverseRGB(COLORREF& c1, COLORREF& c2)//左右颠倒上下颠倒
{
	c1 = RGB(GetRValue(c2), GetGValue(c2), GetBValue(c2));
	c2 = RGB(GetRValue(c1) , GetGValue(c1) , GetBValue(c1));
}
void Work_5()//实现180度翻转
{
	LPCTSTR regionFilePath = _T("2a.jpg");//源文件路径
	LPCTSTR finalFilePath = _T("2f.jpg");//目标图像路径
	CImage regionmage;
	regionmage.Load(regionFilePath);
	int width = regionmage.GetWidth();
	int height = regionmage.GetHeight();
	for (int x = 0; x < width; x++)
	{
		for (int y = 0; y < height ; y++)
		{
			COLORREF c1 = regionmage.GetPixel(x, y);
			COLORREF c2 = regionmage.GetPixel(width-1-x, height-1-y);
			reverseRGB(c1, c2);
			regionmage.SetPixel(x, y, c1);
			regionmage.SetPixel(width - 1 - x, height - 1 - y,c2);
		}
	}
	regionmage.Save(finalFilePath);
}

只将黄色变为红色（原图涉及人脸的颜色，所以要避免人脸的肤色变换）

void yellowRGB(COLORREF& c)//黄色气球变红色
{
	int r = GetRValue(c);
	int g = GetGValue(c);
	int b = GetBValue(c);
	if (r>150&&g>150&&r>=b+20&g>=b+20)
	{
		g = b;
	}
	c = RGB(r, g, b);
}
void Work_6()//黄色变红色
{
	LPCTSTR regionFilePath = _T("2a.jpg");//源文件路径
	LPCTSTR finalFilePath = _T("2g.jpg");//目标图像路径
	CImage regionmage;
	regionmage.Load(regionFilePath);
	int width = regionmage.GetWidth();
	int height = regionmage.GetHeight();
	for (int x = 0; x < width; x++)
	{
		for (int y = 0; y < height; y++)
		{
			COLORREF c = regionmage.GetPixel(x, y);
			yellowRGB(c);
			regionmage.SetPixel(x, y, c);
		}
	}
	regionmage.Save(finalFilePath);
}
