PdfPTable 创建图像的额外单元格
PdfPTable creating extra cells of an image
我正在创建一个包含 pdf 的内存流。 pdf 应该有 4 个不同图像的 table 写在上面。相反，pdf 有一个 table 完全用第一张图片填写，第二页有正确的 4 张图片。它应该看起来像这样
Correct output
但是这张图片在上面
incorrect output
当 fourPerPage 传入 true 时发生错误。当传递 false 时，它可以正常工作并将 4 张图像放在没有 table.
的两页上
代码如下：
public Dictionary<string, MemoryStream> CreateW2FromBitmapImage2Page(List<Employee> info, Employer employerInfo, bool fourPerPage)
{
StringFormat rightAlign = new StringFormat(StringFormatFlags.NoClip);
PdfPTable imageTable = new PdfPTable(2) { WidthPercentage = 82 };
imageTable.DefaultCell.Border = iTextSharp.text.Rectangle.NO_BORDER;
imageTable.DefaultCell.HorizontalAlignment = Element.ALIGN_CENTER;
rightAlign.Alignment = StringAlignment.Far;
var brushColor = Brushes.Black;
var W2ImageDictionary = new Dictionary<string, MemoryStream>();
var font = new System.Drawing.Font("Courier", 12);
var document = new Document(PageSize.LETTER, 0, 0, 0, 0);
foreach (var property in info)

在 for 循环中。因此，您将 table 添加到文档 四次 !
第一次只有一个单元格，即没有完整的行，什么都不画。
第二次有两个单元格，即一个完整的行，所以画了一行。
Copy 2 | Copy 2
第三次是三个单元格，还是只有一个完整的行，所以重新画第一行。
Copy 2 | Copy 2
Copy 2 | Copy 2
第四次有四个单元格，即完整的两行，现在整个table画完了。
Copy 2 | Copy 2
Copy 2 | Copy 2
Copy 2 | Copy 2
Copy B | Copy C
尝试仅在最后一次迭代中调用该行，即
if (i == 4)
document.Add(imageTable);
现在 table 应该只绘制一次，只有在完成时才绘制。
