我正在创建一个带有 pdf 的内存流。pdf 应该有一个包含 4 个不同图像的表格。相反，pdf 有一个表格完全填满了第一张图片，第二页有正确的 4 张图片。它应该看起来像这样
正确的输出
但相反，此图像位于其之上， 输出不正确
当fourPerPage 传入true 时会发生错误。当传递 false 时，它可以正常工作，并将 4 个图像放在没有表格的两页上。
这是代码：
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)
{
Bitmap bmp = new Bitmap(Bitmap.FromFile("copy2.bmp"));
MemoryStream tempImageStream = new MemoryStream();
var writer = PdfWriter.GetInstance(document, tempImageStream);
var employeeCityStateZipCode = CityStateZipDelimiter(property.CityStateZip);
var employerCityStateZipCode = CityStateZipDelimiter(employerInfo.CityStateZip);
document.Open();
writer.CloseStream = false;
for (int i = 1; i < 5; i++)
{
switch (i)
{
case 1:
bmp = new Bitmap(Bitmap.FromFile("copy2.bmp"));
break;
case 2:
bmp = new Bitmap(Bitmap.FromFile("copy2.bmp"));
break;
case 3:
