How can i keep the points im drawing on the image in the picturebox1 when moving the trackBar1?
<p>I am using a <code>trackBar1</code> to move between images I have on the hard disk and I display each image in <code>pictureBox1</code>.</p>

<p>Now I also can draw points red points on each image in the <code>pictureBox1</code>.</p>

<p>What I want to do is that if I drew some points on the current image that is show in the <code>pictureBox1</code> so what I drew will be saved/keep on the current displayed image in the <code>pictureBox1</code>.</p>

<p>I mean that if I drew something then I move the <code>trackBar1</code> forward one tick to the next image so the points will not be show on the next image but if I move the <code>trackBar1</code> backward once I will see on the other image what I drew before. I don't want to save it to the hard disk as file but to visualy to keep what I'm drawing in the <code>pictureBox1</code> on the current position where the <code>trackBar1</code> is now.</p>

<p>And if i move the trackBar1 to another image so the points will be deleted and if i move back ill see the points i drawed on the other image. And so on. Where ever i drawed something to keep it so if i move back ill see what i drawed.</p>

<p>Now in my program i can save each image to the hard disk painted or not painted. So i could also load from the hard disk this images i saved.
But i want to do it in real time without loading the images from hard disk.
Maybe somehow to save it to memory ?</p>
