Bonjour, je me suis créé une application de sudoku (pour l'instant juste disponible sur 
[ Lien ] mais bientot disponible sur Codes-sources) et je travaille avec la classe System.Drawing.Graphics pour imprimer mais je me demandais si il y avait un moyen de transformer en Bitmap (juste de sauvegarder en png)? j'ai essayé en vain de transférer dans un PictureBox mais ca refusait de sauvegarder. Voici un bout de code:
private void docToPrint_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e){
System.Drawing.Font printFont = new Font("Arial", 20, FontStyle.Regular);
e.Graphics.DrawString("Fait par Mykeys Sudoku",printFont,new SolidBrush(Color.Gray),100,200);
e.Graphics.DrawString("http://cyberquebec.ca/mykeys",printFont,new SolidBrush(Color.Gray),100,400);
e.Graphics.DrawString("David L.Pratte",printFont,new SolidBrush(Color.Gray),100,600);
e.Graphics.DrawLine(new Pen(Color.Black,3),40,40,820,40);
e.Graphics.DrawLine(new Pen(Color.Black,3),40,40,40,820);
e.Graphics.DrawLine(new Pen(Color.Black,3),40,820,820,820);
e.Graphics.DrawLine(new Pen(Color.Black,3),820,40,820,820);
e.Graphics.DrawLine(new Pen(Color.Black,3),300,40,300,820);
e.Graphics.DrawLine(new Pen(Color.Black,3),560,40,560,820);
e.Graphics.DrawLine(new Pen(Color.Black,3),40,300,820,300);
e.Graphics.DrawLine(new Pen(Color.Black,3),40,560,820,560);
//Horizontal
e.Graphics.DrawLine(new Pen(Color.Black,1),126,40,126,820);
e.Graphics.DrawLine(new Pen(Color.Black,1),212,40,212,820);
e.Graphics.DrawLine(new Pen(Color.Black,1),386,40,386,820);
e.Graphics.DrawLine(new Pen(Color.Black,1),472,40,472,820);
e.Graphics.DrawLine(new Pen(Color.Black,1),646,40,646,820);
e.Graphics.DrawLine(new Pen(Color.Black,1),732,40,732,820);
//Vertical
e.Graphics.DrawLine(new Pen(Color.Black,1),40,126,820,126);
e.Graphics.DrawLine(new Pen(Color.Black,1),40,212,820,212);
e.Graphics.DrawLine(new Pen(Color.Black,1),40,386,820,386);
e.Graphics.DrawLine(new Pen(Color.Black,1),40,472,820,472);
e.Graphics.DrawLine(new Pen(Color.Black,1),40,646,820,646);
e.Graphics.DrawLine(new Pen(Color.Black,1),40,732,820,732);
e.Graphics.DrawString("Fait par Mykeys Sudoku",printFont,new SolidBrush(Color.Gray),100,850);
e.Graphics.DrawString("http://cyberquebec.ca/mykeys",printFont,new SolidBrush(Color.Gray),100,910);
e.Graphics.DrawString("David L.Pratte",printFont,new SolidBrush(Color.Gray),100,970);
}
Merci de m'aider 
David
