我在设置包含&符号的页面标题文本时遇到了问题,例如“ a&b”。 pdf中“&”之后的文本消失了,可能是因为它是 Aspose 中的保留键。我的代码如下:
PageSetup pageSetup = workbook.getWorksheets().get(worksheetName).getPageSetup();
//calling the function
setHeaderFooter(pageSetup, parameters, criteria)
//function for setting header and footer
def setHeaderFooter(PageSetup pageSetup, parameters, criteria = [:])
{
def selectedLoa=getSelectedLoa(parameters)
if(selectedLoa.length()>110){
String firstLine = selectedLoa.substring(0,110);
String secondLine = selectedLoa.substring(110);
if(secondLine.length()>120){
secondLine = secondLine.substring(0,122)+"...."
}
selectedLoa = firstLine+"\n"+secondLine.trim();
}
def periodInfo=getPeriodInfo(parameters, criteria)
def reportingInfo=periodInfo[0]
def comparisonInfo=periodInfo[1]
def benchmarkName=getBenchmark(parameters)
def isNonComparison = criteria.isNonComparison?
criteria.isNonComparison:false
def footerInfo="&BReporting Period:&B " + reportingInfo+"\n"
if (comparisonInfo && !isNonComparison){
footerInfo=footerInfo+"&BComparison Period:&B " +comparisonInfo+"\n"
}
if (benchmarkName){
footerInfo+="&BBenchmark:&B "+benchmarkName
}
//where I encounterd the issue,selectedLoa contains string with ampersand
pageSetup.setHeader(0, pageSetup.getHeader(0) + "\n&\"Lucida Sans,Regular\"&8&K02-074&BPopulation:&B "+selectedLoa)
//Insertion of footer
pageSetup.setFooter(0,"&\"Lucida Sans,Regular\"&8&K02-074"+footerInfo)
def downloadDate = new Date().format("MMMM dd, yyyy")
pageSetup.setFooter(2,"&\"Lucida Sans,Regular\"&8&K02-074" + downloadDate)
//Insertion of logo
try{
def bucketName = parameters.containsKey('printedRLBucketName')?parameters.get('printedRLBucketName'):null
def filePath = parameters.containsKey('printedReportLogo')?parameters.get('printedReportLogo'): null
// Declaring a byte array
byte[] binaryData
if(!filePath || filePath.contains("null") || filePath.endsWith("null")){
filePath = root+"/images/defaultExportLogo.png"
InputStream is = new FileInputStream(new File(filePath))
binaryData = is.getBytes()
}else {
AmazonS3Client s3client = amazonClientService.getAmazonS3Client()
S3Object object = s3client.getObject(bucketName, filePath)
// Getting the bytes out of input stream of S3 object
binaryData = object.getObjectContent().getBytes()
}
// Setting the logo/picture in the right section (2) of the page header
pageSetup.setHeaderPicture(2, binaryData);
// Setting the script for the logo/picture
pageSetup.setHeader(2, "&G");
// Scaling the picture to correct size
Picture pic = pageSetup.getPicture(true, 2);
pic.setLockAspectRatio(true)
pic.setRelativeToOriginalPictureSize(true)
pic.setHeight(35)
pic.setWidth(Math.abs(pic.getWidth() * (pic.getHeightScale() / 100)).intValue());
}catch (Exception e){
e.printStackTrace()
}
}
在这种情况下,在&符号消失后,我在pdf标头中仅得到“ a”所有其他文本。请为我提出解决方案。我正在使用aspose 18.2

我们在带有以下代码段的PDF页面上添加了标头,但标头文本中包含与号时,我们没有发现任何问题。
// open document
Document document = new Document(dataDir + "input.pdf");
// create text stamp
TextStamp textStamp = new TextStamp("a&bcdefg");
// set properties of the stamp
textStamp.setTopMargin(10);
textStamp.setHorizontalAlignment(HorizontalAlignment.Center);
textStamp.setVerticalAlignment(VerticalAlignment.Top);
// set text properties
textStamp.getTextState().setFont(new FontRepository().findFont("Arial"));
textStamp.getTextState().setFontSize(14.0F);
textStamp.getTextState().setFontStyle(FontStyles.Bold);
textStamp.getTextState().setFontStyle(FontStyles.Italic);
textStamp.getTextState().setForegroundColor(Color.getGreen());
// iterate through all pages of PDF file
for (int Page_counter = 1; Page_counter <= document.getPages().size(); Page_counter++) {
// add stamp to all pages of PDF file
document.getPages().get_Item(Page_counter).addStamp(textStamp);
}
// save output document
document.save(dataDir + "TextStamp_18.8.pdf");
请确保在您的环境中使用Aspose.PDF for Java 18.8。有关添加页面标题的更多信息,您可以访问Add Text Stamp in the Header or Footer section。
如果在添加标题时遇到任何问题,请通过Google云端硬盘,Dropbox等与我们分享您的代码段和生成的PDF文档,以便我们进行调查以帮助您。

是的,当通过Aspose.Cells API在MS Excel电子表格中插入页眉/页脚时,“&”是保留字。为了解决您的问题,您必须放置另一个“&”号,以将“&(“&”号)”粘贴到标题字符串中。请参阅示例代码以供参考: 例如 示例代码:
Workbook wb = new Workbook();
Worksheet ws = wb.getWorksheets().get(0);
ws.getCells().get("A1").putValue("testin..");
String headerText="a&&bcdefg";
PageSetup pageSetup = ws.getPageSetup();
pageSetup.setHeader(0, headerText);
wb.save("f:\\files\\out1.xlsx");
wb.save("f:\\files\\out2.pdf");
希望这会有所帮助。
