How to draw a line with my point drawing method?

Question

Java

I have my own method for drawing a point, you can't use another one. I need to draw a line. We need some ready-made line drawing method that can be easily changed.

Answer 1

Most likely, your method takes X and Y coordinate parameters. Therefore, you just need to call it in a loop, changing one of the coordinates in each iteration: X for a horizontal line, Y for a vertical one. Well, or both - for the diagonal)

Answer 2

You can use the Bresenham algorithm

Answer 3

width=300;
height=300;
CreateWindowEx(hwnd,width,height);
color = red;
x = 100;
for(int i=0;i<100;i++)
{
    SetPixel(i,x,red);//горизонтальная линия
    SetPixel(x,i,red);//вертикальная линия
    SetPixel(i,i,red);//диагональная линия
}
SwapBuffers(doubleBuffer,hwnd);

I can't vouch for the correctness of the code I haven't coded for a long time
