This file contains all the changes in documentation in the packagecom.itextpdf.kernel.pdf.canvas.parser.listeneras colored differences. Deletions are shownlike this, and additions are shown like this.
If no deletions or additions are shown in an entry, the HTML tags will be what has changed. The new HTML tags are shown in the differences. If no documentation existed, and then some was added in a later version, this change is noted in the appropriate class pages of differences, but the change is not shown on this page. Only changes in existing text are shown here. Similarly, documentation which was inherited from another class or interface is not shown here.
Note that an HTML error in the new documentation may cause the display of other documentation changes to be presented incorrectly. For instance, failure to close a tag will cause all subsequent paragraphs to be displayed differently.
This class is designed to search for the occurrences of a regular expression and return the resultant rectangles. Do note that this class holds all text locations and can't be used for processing multiple pages. If you want to extract text from several pages of pdf document you have to create a new instance of RegexBasedLocationExtractionStrategy for each page.Here is an example of usage with new instance per each page:
PdfDocument document = new PdfDocument(new PdfReader("...")); for (int i = 1; i <= document.getNumberOfPages(); ++i) { RegexBasedLocationExtractionStrategy extractionStrategy = new RegexBasedLocationExtractionStrategy(""); PdfCanvasProcessor processor = new PdfCanvasProcessor(extractionStrategy); processor.processPageContent(document.getPage(i)); for (IPdfTextLocation location : extractionStrategy.getResultantLocations()) { //process locations ... } }
