1.实现红色部分变蓝

\#include<iostream>

\#include<atlimage.h>

using namespace std;

void swapRGWhenGedMax(COLORREF &c)

int r = GetRValue(c);

int g = GetGValue(c);

int b = GetBValue(c);

if (r > g && r > b)

swap(r, b);

c = RGB(r, g, b);

int main()

const char \*srcFilePath = "1a.jpg";

const char \*destFilePath = "1b.jpg";

CImage srclmage;

srclmage.Load(srcFilePath);

int width = srclmage.GetWidth();

int height = srclmage.GetHeight();

for (int x = 0; x < width; x++)

for (int y = 0; y < height; y++)

COLORREF c = srclmage.GetPixel(x, y);

swapRGWhenGedMax(c);

srclmage.SetPixel(x, y, c);

srclmage.Save(destFilePath);

return 0;

2.实现图片反色

\#include<iostream>

\#include<atlimage.h>

using namespace std;

void swapRGWhenGedMax(COLORREF &c)

int r = GetRValue(c);

int g = GetGValue(c);

int b = GetBValue(c);

c = RGB(255 - r, 255 - g, 255 - b);

int main()

const char \*srcFilePath = "2a.jpg";

const char \*destFilePath = "2b.jpg";

CImage srclmage;

srclmage.Load(srcFilePath);

int width = srclmage.GetWidth();

int height = srclmage.GetHeight();

for (int x = 0; x < width; x++)

for (int y = 0; y < height; y++)

COLORREF c = srclmage.GetPixel(x, y);

swapRGWhenGedMax(c);

srclmage.SetPixel(x, y, c);

srclmage.Save(destFilePath);

return 0;

3.提取

\#include<iostream>

\#include<atlimage.h>

using namespace std;

void swapRGWhenGedMax(COLORREF &c)

int r = GetRValue(c);

int g = GetGValue(c);

int b = GetBValue(c);

if (70 < r && r< 99 && b < 30) //防止后期洞的出现，将r调到大于99

r = 103;

g = 29;

b = 4;

if (r < 99)

r = 255;

g = 255;

b = 255;

c = RGB(r, g, b);

int main()

const char \*srcFilePath = "3a.jpg";

const char \*destFilePath = "3b3.jpg";

CImage srclmage;

srclmage.Load(srcFilePath);

int width = srclmage.GetWidth();

int height = srclmage.GetHeight();

for (int x = 0; x < width; x++)

for (int y = 0; y < height; y++)

COLORREF c = srclmage.GetPixel(x, y);

swapRGWhenGedMax(c);

srclmage.SetPixel(x, y, c);

srclmage.Save(destFilePath);

return 0;
