我想获得图像像素的R,G和B值。我已经使用HDC完成了它,但现在我想用Gdi +和输入图像完成它。
到目前为止,这是我的代码:
#include <iostream>
#include <stdlib.h>
#include <windows.h>
#include "gdiplus.h"
#include "stdio.h"
#include "iostream"
using namespace Gdiplus;
using namespace std;
void main(int argc, char* argv[])
{
Bitmap* mybitmap = new("bink.bmp");
int x=0;
int y=0;
Color pixelColor;
//Color pixelcolor[1000][1000];
for ( x = 0; x < 640; x++ )
{
for ( y = 0; y < 480; y++ )
{
//Color pixelColor[x][y] = mybitmap->GetPixel(x,y);
mybitmap->GetPixel(x,y, &pixelColor);
cout << "Pixel color " << x << ", " << y; "is " << pixelColor;
//cout << "Pixel color " << x << ", " << y; "is " << pixelColor[x][y];
}
}
}
它不起作用......你能以某种方式帮助吗?
答案 0 :(得分:0)
你应该使用pixelColor.GetGreen,pixelColor.GetRed,pixelColor.GetBlue
