i Wrote some basic code on something i saw here i while ago and was wondering what people could do with it. it uses a console and you can draw on the console or the entire desktop. i was hopping there was thing people could do to add or improve my code. if you get linker errors you have to add the libgdi32.a library Main.cpp
#define _WIN32_WINNT 0x0500
#include <iostream>
#include <windows.h>
#include "Pen.h"
using namespace std;
int main()
{
Draw draw(0); ///Sets if the drawing is only in the cmd console or in the entire screen
draw.SetPen(255,100,0,10); ///sets pen color and size SetPen(RED,GREEN,BLUE,PEN SIZE);
while(true) // loop
{
draw.Pen(); /// draws pen
Sleep(10);
}//end
return 0;
} Pen.h
