C++ Pixel Scanner

[radnomguywfq3]

I wrote this and released it else where under a different name, but I never made use of it and neither did they so here you go :O Tool lazy to clean it up, although the code looks pretty neat already soh. Don't redistribute it in any form(be it compiled or not) without my permission. Under

Header :

#ifndef PIXELSCANNINGWRAPPER_H_
#define PIXELSCANNINGWRAPPER_H_
#include <windows.h>
struct Img
{
COLORREF crPixSearch[30][30];
int iX,iY;
int iWidth, iHeight;
};

struct Vector2D {
int iX,iY;
};

struct Rect {
int iX,iY,iWidth,iHeight;
};

Vector2D searchForImg(Img &Input, Rect &SearchBounds, float delay);
HBITMAP getImage(LPCWSTR path, bool resource);
int loadImage(Img &Input, HBITMAP &hBitmapSource,Rect rect, float delay);

[b] I wrote this a while ago, I'm not doing it, but when you use this you should find problems(such as returning whole structs instead of pointers to them. So fix that.
