我使用iTextSharp創建了一個用於檢查打印目的的PDF。我的問題是，我不能在支票信封上的小窗口打印支票上打印的名稱/地址。地址線之間的間隔太大。我在HTML文檔中的字體標籤中設置了行高，但不會繼續。HTML到iTextSharp行高轉換
這裏是地址的一部分，具體爲：
conn.Open();
using (SqlDataReader itemReader = strSQL.ExecuteReader())
{
checksHolder.InnerHtml += "<table cellSpacing=\"0\" cellPadding=\"0\" border=\"0\" width=\"100%\">\n";
while (itemReader.Read())
{
if (i % 3 == 0 && i != 0)
{
checksHolder.InnerHtml += "</table>\n";
checksHolder.InnerHtml += "<!-- pagebreak -->\n";
checksHolder.InnerHtml += "<table cellSpacing=\"0\" cellPadding=\"0\" border=\"0\" width=\"100%\">\n";
f = 0;
}
if (i > 0 && i % 3 != 0)
{
checksHolder.InnerHtml += "<tr><td colspan=\"3\"><br/><br/><br/><br/><br/><br/>";
checksHolder.InnerHtml += "</td></tr>\n";
}
String[] tmpArray = getConsignorInfo(itemReader["check_cs_id"].ToString());
int CheckNum = Int32.Parse(itemReader["check_number"].ToString());

我只有半英寸把名稱/地址轉換。我已經試過用8px和8來指定線高度以防萬一。沒有工作。有誰知道我需要如何格式化HTML以使行高保持不變？提前致謝。
如果您使用不推薦使用的HTMLWorker類或較新的XML Worker，尚不清楚。沒有這些信息，你的問題就無法回答。 –
@BrunoLowagie謝謝你的回覆。我正在使用HTMLWorker類。不知道它已被棄用。不過，我不介意切換到XMLWorker。只要任何工作正確。 – James
