是否有iText的方式画一个PDF文档中的矩形？
Answer 1:
这里是解决方案。 由于迪伦麦克朗。
PdfWriter writer = ...;
PdfContentByte cb = writer.getDirectContent();
cb.saveState();
cb.setColorStroke(Color.black);
cb.rectangle(x,y,x1,y1);
cb.stroke();
cb.restoreState();
Answer 2:
在.NET版本我只是创建带有边框的表格。 我知道这是不是Java，但也许下面的代码将帮助你。
iTextSharp.text.Document document = new iTextSharp.text.Document(PageSize.LETTER, 20, 20, 20, 20);
PdfPTable table;
PdfPCell cell;
// single element w/ border
table = new PdfPTable(1);
cell = new PdfPCell(new Phrase("BOLD WORDS", FontFactory.GetFont(FontFactory.HELVETICA_BOLD, 11, Font.BOLD)));
cell.BorderWidth = 2;
cell.Padding = 5;
cell.PaddingTop = 3;
cell.HorizontalAlignment = Element.ALIGN_CENTER;
table.AddCell(cell);
table.SetWidthPercentage(new float[1] { 598f }, PageSize.LETTER);
table.HorizontalAlignment = Element.ALIGN_CENTER;
document.Add(table);

一个更完整的例子是： http://www.mikesdotnetting.com/Article/88/iTextSharp-Drawing-shapes-and-Graphics
Answer 4:
public static void drawRectangle(PdfContentByte content, float width, float height) {
content.saveState();
PdfGState state = new PdfGState();
state.setFillOpacity(0.6f);
content.setGState(state);
content.setRGBColorFill(0xFF, 0xFF, 0xFF);
content.setLineWidth(3);
content.rectangle(0, 0, width, height);
content.fillStroke();
content.restoreState();
}
从iText的API的
Answer 5:
private static void rect(PdfWriter writer) {
PdfContentByte cb = writer.getDirectContent();
try {
cb.setFontAndSize(BaseFont.createFont(BaseFont.HELVETICA, BaseFont.WINANSI, false), 24);
cb.rectangle(140f,140f,280f,420f);
cb.stroke();
} catch (DocumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
