C# 打印多页tif

注意点：

1.计算image对象总页数

image.GetFrameCount(FrameDimension.Page);

2.初始化当前页，并获取指定页内容

image.SelectActiveFrame(FrameDimension.Page, m_CurrentPage);

3.设置PrintPage时间PrintPageEventArgs参数值，判断是否有额外页打印（次数是打印多页关键）

e.HasMorePages = (m_CurrentPage < m_PageCount);

　　

基本DEMO（转载）

private Image m_Image;
private Int32 m_CurrentPage;
private Int32 m_PageCount;

private void Form1_Load(object sender, EventArgs e)
{
    m_Image = Image.FromFile(".\\Test-2-Page-Image.tif");
    m_PageCount = m_Image.GetFrameCount(FrameDimension.Page);
}

private void printDocument_BeginPrint(object sender, PrintEventArgs e)
{
    m_CurrentPage = 0;
    m_PageCount = m_Image.GetFrameCount(FrameDimension.Page);
}

private void printDocument_PrintPage(object sender, PrintPageEventArgs e)
{
    m_Image.SelectActiveFrame(FrameDimension.Page, m_CurrentPage);
    e.Graphics.DrawImage(m_Image, 0, 0);
    ++m_CurrentPage;
    e.HasMorePages = (m_CurrentPage < m_PageCount);
}

private void btnPrint_Click(object sender, EventArgs e)
{
    printDocument.Print();
}
