Using OnEndPage, I add a footer to my PDF created with iTextSharp. The footer font gets progressively bolder with each page.
How can I create consistent NORMAL fonts in my footer?
Here is my code:
public override void OnEndPage(PdfWriter writer, Document doc)
{
iTextSharp.text.Image gif = null;
if (FooterImage)
{
if (File.Exists(PathImages))
{
gif = iTextSharp.text.Image.GetInstance(PathImages);
gif.ScaleToFit(75f, 75f);
gif.SetAbsolutePosition(0, 0);
}
}
string sFooter = string.Empty;
if (FooterURL != null && FooterURL.Length > 0)
{
sFooter = FooterURL + " ";
}
if (FooterDate != null && FooterDate.Length > 0)
{
sFooter += FooterDate + " ";
}
if (FooterPage)
{
sFooter += "Page " + doc.PageNumber.ToString();
}
PdfPTable footerTbl = new PdfPTable(1);
footerTbl.TotalWidth = 900;
footerTbl.HorizontalAlignment = Element.ALIGN_CENTER;
Phrase ph = new Phrase(sFooter, FontFactory.GetFont(FontFactory.TIMES, 10, iTextSharp.text.Font.NORMAL));
PdfPCell cell = new PdfPCell(ph);
cell.Border = 0;
cell.PaddingLeft = 10;
footerTbl.AddCell(cell);
if (FooterImage)
{
PdfContentByte cbfoot = writer.DirectContent;
PdfTemplate tpl = cbfoot.CreateTemplate(gif.Width / 5, gif.Height / 5);
tpl.AddImage(gif);
cbfoot.AddTemplate(tpl, doc.PageSize.Width - 100, 10);
}
footerTbl.WriteSelectedRows(0, -1, 10, 30, writer.DirectContent);
}
In the old days, when there wasn't as much choice as today regarding fonts, people used workarounds to create bold fonts. One way to make a font bold, was by adding the same text over and over again at the same position. I think that this is happening to you.
When you use page events correctly, the onEndPage() method is triggered automatically each time a page ends. My guess is that you're doing something very wrong that triggers the onEndPage() many times. Maybe you are called the onEndPage() from your code, maybe you're adding the page event to the writer more than once (and page events are cumulative).
If I have to guess, I would guess that you are doing the latter. My guess is based on the fact that you are using variables such as FooterImage in your onEndPage() method. How are you setting that variable. If you are setting it in the constructor of the page event and you're adding the new page event over and over again to the writer, then you're doing it wrong.

Does anyone have an idea how we can add outlines to text (text outline) within powerpoint templates (ppxt) using Apache POI? What I have gathered so far is that the XSLFTextRun class does not have a method to get/ set the text outline for a given run element.
And as such, I could only persist the following font/ text styles:
def fontStyles(textBox: XSLFTextBox, textRun: XSLFTextRun): Unit = {
val fontFamily = textRun.getFontFamily
val fontColor = textRun.getFontColor
val fontSize = textRun.getFontSize
val fontBold = textRun.isBold
val fontItalic = textRun.isItalic
val textAlign = textRun.getParagraph.getTextAlign
textBox.getTextParagraphs.foreach { p =>
p.getTextRuns.foreach { tr =>
tr.setFontFamily(fontFamily)
tr.setFontColor(fontColor)
tr.setFontSize(fontSize)
tr.setBold(fontBold)
tr.setItalic(fontItalic)
tr.getParagraph.setTextAlign(textAlign)
}
}
}
Is it possible to add text outline?
Any assistance/ suggestions would be highly appreciated.
Apache poi uses underlying ooxml-schemas classes. Those are auto generated from Office Open XML standard. So they are more complete than the high level XSLF classes. Of course they are much less convenient.
So if somewhat is not implemented in high level XSLF classes, we can get the underlying CT classes and do it using those. In case of XSLFTextRun we can get the CTRegularTextRun object. Then we can look whether there are run properties already. If not, we add one. Then we look whether there is outline set already. If so, we unset it, because we want set it new. Then we set a new outline. This simply is a line having a special color. That line is represented by CTLineProperties object. So we need to have methods to create that CTLineProperties, to set CTLineProperties to the XSLFTextRun and get CTLineProperties from XSLFTextRun.

I have created a report using dynamic reports and add a page number component and set its horizontal Alignment as right. But in printed report, page number doesn't seem to be fully right aligned.
Check this image to see the alignment issue
Note :- No right padding for page number and no trailing white spaces in page number expression.
versions used :-
dynamicreports - 3.0.2
jasperreports - 4.8.0
After lots of time spent on debugging and checking source code of dynamic reports I found the issue. I am posting this for anyone who find its helpful.
When we add PageXofYBuilder, what dynamic reports actually doing is create two text fields for 'x' and 'y'. If the component is right aligned then text field for 'x' is right aligned and text field for 'y' is left aligned with fixed width. The width of text field for 'y' is calculated as width required for a 6 digit number based on the selected font, font size and horizontal padding.
Check out the below code of pageXofY method in the class ComponentTransform which is responsible for creating the page number field in jasper design for more details :
private DRDesignList pageXofY(DRIPageXofY pageXofY, DefaultStyleType defaultStyleType) throws DRException {

I've started using PDFClown some weeks ago. My purpose is multi-word highlighting, mainly on newspapers. Starting from the org.pdfclown.samples.cli.TextHighlightSample example, I succeeded in extracting multi-word positions and highlighting them. I even solved some problems due to text ordering and matching in most cases.
Unfortunately my framework includes FPDI and it does not consider PDFAnnotations. So, all the content outside of a page content stream, like text annotations and other so called markup annotations, get lost.
So any suggestion on creating "Text Highlighting" with PdfClown and without using PDF annotations?
To not have the highlight in an annotation but instead in the actual page content stream, one has to put the graphic commandos into the page content stream which in case of the org.pdfclown.samples.cli.TextHighlightSample example are implicitly put into the normal annotation appearance stream.
This can be implemented like this:
org.pdfclown.files.File file = new org.pdfclown.files.File(resource);
Pattern pattern = Pattern.compile("S", Pattern.CASE_INSENSITIVE);
TextExtractor textExtractor = new TextExtractor(true, true);
for (final Page page : file.getDocument().getPages())
{
final List<Quad> highlightQuads = new ArrayList<Quad>();
Map<Rectangle2D, List<ITextString>> textStrings = textExtractor.extract(page);
final Matcher matcher = pattern.matcher(TextExtractor.toString(textStrings));
textExtractor.filter(textStrings, new TextExtractor.IIntervalFilter()
{
#Override
public boolean hasNext()
{
return matcher.find();
}
#Override
public Interval<Integer> next()
{
return new Interval<Integer>(matcher.start(), matcher.end());
}
#Override
public void process(Interval<Integer> interval, ITextString match)
{
{
Rectangle2D textBox = null;
for (TextChar textChar : match.getTextChars())
{
Rectangle2D textCharBox = textChar.getBox();
if (textBox == null)
{
textBox = (Rectangle2D) textCharBox.clone();
}
else
{
if (textCharBox.getY() > textBox.getMaxY())
{
highlightQuads.add(Quad.get(textBox));
textBox = (Rectangle2D) textCharBox.clone();
}
else
{
textBox.add(textCharBox);
}
}
}
highlightQuads.add(Quad.get(textBox));
}
}
#Override
public void remove()
{
throw new UnsupportedOperationException();
}
});
// Highlight the text pattern match!
ExtGState defaultExtGState = new ExtGState(file.getDocument());
defaultExtGState.setAlphaShape(false);
defaultExtGState.setBlendMode(Arrays.asList(BlendModeEnum.Multiply));
PrimitiveComposer composer = new PrimitiveComposer(page);
composer.getScanner().moveEnd();
// TODO: reset graphics state here.
composer.applyState(defaultExtGState);
composer.setFillColor(new DeviceRGBColor(1, 1, 0));
{
for (Quad markupBox : highlightQuads)
{
Point2D[] points = markupBox.getPoints();
double markupBoxHeight = points[3].getY() - points[0].getY();
double markupBoxMargin = markupBoxHeight * .25;
composer.drawCurve(new Point2D.Double(points[3].getX(), points[3].getY()),
new Point2D.Double(points[0].getX(), points[0].getY()),
new Point2D.Double(points[3].getX() - markupBoxMargin, points[3].getY() - markupBoxMargin),
new Point2D.Double(points[0].getX() - markupBoxMargin, points[0].getY() + markupBoxMargin));
composer.drawLine(new Point2D.Double(points[1].getX(), points[1].getY()));
composer.drawCurve(new Point2D.Double(points[2].getX(), points[2].getY()),
new Point2D.Double(points[1].getX() + markupBoxMargin, points[1].getY() + markupBoxMargin),
new Point2D.Double(points[2].getX() + markupBoxMargin, points[2].getY() - markupBoxMargin));
composer.fill();
}
}
composer.flush();
}
file.save(new File(RESULT_FOLDER, "multiPage-highlight-content.pdf"), SerializationModeEnum.Incremental);
(HighlightInContent.java method testHighlightInContent)
You will recognize the text extraction frame from the original example. Merely now the quads from a whole page are collected before they are processed, and the processing code (which mostly has been borrowed from TextMarkup.refreshAppearance()) draws forms representing the quads into the page content.
Beware, to make this work generically, the graphics state has to be reset before inserting the new instructions (the position is marked with a TODO comment). This can be done either by applying save/restore state or by actually counteracting unwanted changed state entries. Unfortunately I did not see how to do the former in PDF Clown and have not yet had the time to do the latter.
I have a JTextPane (or JEditorPane) in which I want to add some buttons to format text (as shown in the picture).
When I change the selected text to Bold (making a new Style), the font family (and others attributes) also changes. Why? I want to set (or remove) the bold attribute in the selected text and other stays unchanged, as they were.
This is what I'm trying:
private void setBold(boolean flag){
HTMLDocument doc = (HTMLDocument) editorPane.getDocument();
int start = editorPane.getSelectionStart();
int end = editorPane.getSelectedText().length();
StyleContext ss = doc.getStyleSheet();
//check if BoldStyle exists and then add / remove it
Style style = ss.getStyle("BoldStyle");
if(style == null){
style = ss.addStyle("BoldStyle", null);
style.addAttribute(StyleConstants.Bold, true);
} else {
style.addAttribute(StyleConstants.Bold, false);
ss.removeStyle("BoldStyle");
}
doc.setCharacterAttributes(start, end, style, true);
}
But as I explained above, other attributes also change:
Any help will be appreciated. Thanks in advance!
http://oi40.tinypic.com/riuec9.jpg
What you are trying to do can be accomplished with one of the following two lines of code:
new StyledEditorKit.BoldAction().actionPerformed(null);
or
editorPane.getActionMap().get("font-bold").actionPerformed(null);
... where editorPane is an instance of JEditorPane of course.
Both will seamlessly take care of any attributes already defined and supports text selection.
Regarding your code, it does not work with previously styled text because you are overwriting the corresponding attributes with nothing. I mean, you never gather the values for the attributes already set for the current selected text using, say, the getAttributes() method. So, you are effectively resetting them to whatever default the global stylesheet specifies.
The good news is you don't need to worry about all this if you use one of the snippets above. Hope that helps.
I made some minor modifications to your code and it worked here:
private void setBold(boolean flag){
HTMLDocument doc = (HTMLDocument) editorPane.getDocument();
int start = editorPane.getSelectionStart();
int end = editorPane.getSelectionEnd();
if (start == end) {
return;
}
if (start > end) {
int life = start;
start = end;
end = life;
}
StyleContext ss = doc.getStyleSheet();
//check if BoldStyle exists and then add / remove it
Style style = ss.getStyle(editorPane.getSelectedText());
if(style == null){
style = ss.addStyle(editorPane.getSelectedText(), null);
style.addAttribute(StyleConstants.Bold, true);
} else {
style.addAttribute(StyleConstants.Bold, false);
ss.removeStyle(editorPane.getSelectedText());
}
doc.setCharacterAttributes(start, end - start, style, true);
}
I'm trying to discover paragraphs/titles in word documents.
I use Apache POI to do this.
An example that I use is:
fs = new POIFSFileSystem(new FileInputStream(filesname));
HWPFDocument doc = new HWPFDocument(fs);
WordExtractor we = new WordExtractor(doc);
ArrayList titles = new ArrayList();
try {
for (int i = 0; i < we.getText().length() - 1; i++) {
int startIndex = i;
int endIndex = i + 1;
Range range = new Range(startIndex, endIndex, doc);
CharacterRun cr = range.getCharacterRun(0);
if (cr.isBold() || cr.isItalic() || cr.getUnderlineCode() != 0) {
while (cr.isBold() || cr.isItalic() || cr.getUnderlineCode() != 0) {
i++;
endIndex += 1;
range = new Range(endIndex, endIndex + 1, doc);
cr = range.getCharacterRun(0);
}
range = new Range(startIndex, endIndex - 1, doc);
titles.add(range.text());
}
}
}
catch (IndexOutOfBoundsException iobe) {
//sometimes this happens have to find out why.
}`enter code here`
This works for all bold, italic or underlined text.
But what I want is to discover the font that is used most often. And then to discover variations compared to that font style. Anyone an Idea?
Well, some thoughts would be to try some of the following:
cr.getFontSize() could be used at the beginning of a paragraph to see if the range changes font size. That in conjunction with bold, italic or underlined would be a good identifier.
cr.getFontName() could also be used to determine when and where the font changes in a given range.
cr.getColor() would be another possibility to help identify if the user is using different colors for a font.
I guess I would iterate over the range and create multiple CharacterRun items each time the text characteristics change. Then evaluate each item based on position in the paragraph as well as all of the afore-mentioned characteristics (size, color, name, bold, italics, etc.). Perhaps create some sort of weighting scale based on the most common values.
It might also be of value to create a Title object and store the values for each set of characteristics to help optimize searches in later character runs in the same document.
You might want to take a look at the buildParagraphTagAndStyle method in Tika's WordExtractor:
https://svn.apache.org/repos/asf/tika/trunk/tika-parsers/src/main/java/org/apache/tika/parser/microsoft/WordExtractor.java
For HWPF (.doc), to call it you'd do:
StyleDescription style =
document.getStyleSheet().getStyleDescription(p.getStyleIndex());
TagAndStyle tas = buildParagraphTagAndStyle(
style.getName(), (parentTableLevel>0)
);
For XWPF (.docx) you'd do:
XWPFStyle style = styles.getStyle(paragraph.getStyleID());
TagAndStyle tas = WordExtractor.buildParagraphTagAndStyle(
style.getName(), paragraph.getPartType() == BodyType.TABLECELL
);
It will be easier if you process the data by converting it into paragraphs.
WordExtractor we = new WordExtractor(doc);
String[] para = we.getParagraphText();
Then work paragraph wise. If your code already couldn't figure out the titles, then you can check for bold and underlines in each paragraph.
The paragraphs function as follows:
for(int i=0;i<para.length;i++)
{
System.out.println("Length of paragraph "+(i+1)+": "+ para[i].length());
System.out.println(para[i].toString());
}
