我在设置包含“a&b”之类的 & 符号的页眉文本时遇到了问题。'&' 后面的文字 在 pdf 中消失可能是因为它是Aspose中的保留键。我的代码如下所示:
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,我在所有其他文本的 pdf 标题中只得到“a”。请为此建议我一个解决方案。我正在使用 aspose 18.2
