使用 MSDN 中关于如何打印 Windows 窗体的代码示例,我有一个修改后的我的,先调出打印机选项然后打印,但我一直收到一个空白页。使用CopyFromScreen
,我给出了表单源 X 和 Y 的坐标,但是对于我尝试过的目的地0
以及this.Location.X & Y
. 有没有另一种方法来捕获图像?
private void printButton_Click(object sender, EventArgs e)
{
CaptureScreen();
printDialog1.AllowSomePages = true;
printDialog1.ShowHelp = true;
printDialog1.Document = printDoc1;
DialogResult result = printDialog1.ShowDialog();
if (result == DialogResult.OK)
{
printDoc1.Print();
}
}
private void CaptureScreen()
{
Graphics myGraphics = this.CreateGraphics();
Size s = this.Size;
memoryImage = new Bitmap(s.Width, s.Height, myGraphics);
Graphics memoryGraphics = Graphics.FromImage(memoryImage);
memoryGraphics.CopyFromScreen(this.Location.X, this.Location.Y, 0, 0, s);
}
void printDoc1_PrintPage(object sender, PrintPageEventArgs e)
{
e.Graphics.DrawImage(memoryImage, 0, 0);
}
