Question

我确实有问题,我有一个有短语的细胞, 我想在短语的左边有一个小图标, 但是每个元素都是在一条新线上

这是我的代码返回单元格:

var cell = new PdfPCell();
Bitmap bitmap = new Bitmap(21, 21);
Graphics g = Graphics.FromImage(bitmap);

g.Clear(Color.White);

SolidBrush brush = new SolidBrush(colour);
g.FillEllipse(brush, 0, 0, 20, 20);
brush.Dispose();

g.DrawImageUnscaled(bitmap, 0, 0);

g.Dispose();

var imgIcon = iTextSharp.text.Image.GetInstance(bitmap, System.Drawing.Imaging.ImageFormat.Jpeg);
bitmap.Dispose();
//imgIcon.Alignment = iTextSharp.text.Image.TEXTWRAP | iTextSharp.text.Image.ALIGN_RIGHT;
cell.AddElement(imgIcon);

var phrase = new Phrase(o.ToString(), Report.Fonts.Table);
cell.AddElement(phrase);

//this code scales the image so that it does not fit the cell
foreach (IElement element in cell.CompositeElements)
{
     PdfPTable tblImg = element as PdfPTable;
     if (tblImg != null)
     {
         tblImg.TotalWidth = 10;
         tblImg.LockedWidth = true;
     }
}
return cell;

这是输出 :

如有任何帮助,将不胜感激。

--edit: here is the output with imgIcon s alignment property set

Answer 1

iTextSharp < code> Image 对象显示为 < em> block 元素( 在 CSS 术语中) 。您需要将 < code> Image 明确包裹在 < code > Chunk 中, 才能获得 < em > inline 显示, 类似 :

PdfPTable table = new PdfPTable(1) {
  TotalWidth = 100, LockedWidth = true, 
  HorizontalAlignment = Element.ALIGN_LEFT
};
PdfPCell cell = new PdfPCell();
Phrase p = new Phrase(new Chunk(image, 0, 0));
p.Add(new Phrase("Print"));
cell.AddElement(p);
table.AddCell(cell);

cell = new PdfPCell();
p = new Phrase(new Chunk(image, 0, 0));
p.Add(new Phrase("A long phrase that will make the PdfPCell wrap it s containing text."));
cell.AddElement(p);
table.AddCell(cell);
document.Add(table);

Answer 2

我认为,这一答案:

文本中的图像对齐?

可能找到答案。您需要设置图像对齐 :

....
imgIcon.Alignment = 6;
cell.AddElement(imgIcon);
....
