Question

我正在使用Aspose.PDF .NET 10.4（撰写本文时最新）。我正在使用他们的DOM api（不是生成器，因为它被弃用）。

如何将表格单元格中的文字逆时针旋转90度？

这是我尝试的但是矩形的旋转没有影响。

Table table =  new Table();
table.DefaultCellBorder = new BorderInfo(BorderSide.All, 1f, Color.Black);
table.DefaultCellPadding = new MarginInfo(5, 5, 5, 5);

var headerRow = table.Rows.Add();
headerRow.FixedRowHeight = 100;
headerRow.DefaultCellTextState.HorizontalAlignment = HorizontalAlignment.Center;

for (int hc = 0; hc < 20; hc++)
{
    var cell = headerRow.Cells.Add();
    cell.BackgroundColor = Color.Red;
    cell.DefaultCellTextState.ForegroundColor = Color.White;
    cell.DefaultCellTextState.FontStyle = FontStyles.Bold;

    var h = new TextFragment("header-" + hc);
    h.Rectangle.Rotate(270); //this does nothing
    cell.Paragraphs.Add(h);
}

for (int r = 0; r < 15; r++)
{
    var row = table.Rows.Add();
    for (int c = 0; c < 20; c++)
    {
        row.Cells.Add(r + "-" + c);
    }
}

Document doc = new Document();
Page page = doc.Pages.Add();
page.Paragraphs.Add(table);
doc.Save("c:\temp\table.pdf");

Answer 1

如下：

row.Cells[0].VerticalTextRotationAngle = VerticalTextRotationType.AntiClockWise;

Answer 2

开始Aspose.Pdf 17.5的最新版本，可以添加旋转的文本片段。将角度值（以度为单位）设置为TextState.Rotation属性。

string myDir = @"D:\Temp\000\";
Aspose.Pdf.Table table = new Aspose.Pdf.Table();
table.DefaultCellBorder = new Aspose.Pdf.BorderInfo(Aspose.Pdf.BorderSide.All, 1f, Aspose.Pdf.Color.Black);
table.DefaultCellPadding = new Aspose.Pdf.MarginInfo(5, 5, 5, 5);

Row headerRow = table.Rows.Add();
headerRow.FixedRowHeight = 100;
headerRow.DefaultCellTextState.HorizontalAlignment = Aspose.Pdf.HorizontalAlignment.Center;

for (int hc = 0; hc < 4; hc++)
{
    Cell cell = headerRow.Cells.Add();
    cell.BackgroundColor = Aspose.Pdf.Color.Red;
    cell.DefaultCellTextState.ForegroundColor = Aspose.Pdf.Color.White;
    cell.DefaultCellTextState.FontStyle = FontStyles.Bold;

    TextFragment h = new TextFragment("header-" + hc);

    //Set rotation
    h.TextState.Rotation = 270;

    cell.Paragraphs.Add(h);
}

for (int r = 0; r < 15; r++)
{
    Row row = table.Rows.Add();
    for (int c = 0; c < 4; c++)
    {
        row.Cells.Add(r + "-" + c);
    }
}

Document doc = new Document();
Page page = doc.Pages.Add();
page.Paragraphs.Add(table);
doc.Save(myDir + "TextRotate_inCell_17_5.pdf");
