function Leadtools.Annotations.Core.AnnCodecs()
!MISSING Scrap '_RTJavaScript_Class_SYNTAX'!
This class supports loading and saving annotation objects from/to an XML string as well as getting information on previously saved annotations data.
This class also supports saving and loading multi-page annotation data where each page contains a full Annotation Container.
Use the Save method to save an annotation container as XML data. You can then use the browser capabilities to save this XML data to disk or use a Web Service to store it on a server. The SerializeOptions property can be used to set saving options and monitor the objects being saved.
Use the Load method to load an annotation container from XML data. The XML data must be previously loaded from disk using the browser capabilities or obtained from a server using a Web Service. The DeserializeOptions property can be used to set loading options, monitor the objects being loaded and handle errors.
Use the GetInfo to check if an XML data contains valid annotations data such as the format and number of pages.
LEADTOOLS supports saving multiple annotations into the same data. This can be used to save the annotations of a multi-page document in the same data.
example: function SiteLibrary_DefaultPage$example() { // Create a new annotation container, 8.5 by 11 inches var container = new Leadtools.Annotations.Core.AnnContainer(); // Size must be in annotation units (1/720 of an inch) container.set_size(Leadtools.LeadSizeD.create(8.5 * 720, 11 * 720)); var inch = 720.0; // Add a red line object, from 1in 1in to 2in 2in var lineObj = new Leadtools.Annotations.Core.AnnPolylineObject(); lineObj.get_points().add(Leadtools.LeadPointD.create(1 * inch, 1 * inch)); lineObj.get_points().add(Leadtools.LeadPointD.create(2 * inch, 2 * inch)); lineObj.set_stroke(Leadtools.Annotations.Core.AnnStroke.create(Leadtools.Annotations.Core.AnnSolidColorBrush.create("red"), Leadtools.LeadLengthD.create(1))); container.get_children().add(lineObj); // Add a blue on yellow rectangle from 3in 3in to 4in 4in var rectObj = new Leadtools.Annotations.Core.AnnRectangleObject(); rectObj.set_rect(Leadtools.LeadRectD.create(3 * inch, 3 * inch, 1 * inch, 1 * inch)); rectObj.set_stroke(Leadtools.Annotations.Core.AnnStroke.create(Leadtools.Annotations.Core.AnnSolidColorBrush.create("blue"), Leadtools.LeadLengthD.create(1))); rectObj.set_fill(Leadtools.Annotations.Core.AnnSolidColorBrush.create("yellow")); container.get_children().add(rectObj); // Show the container this.showContainer("Before save", container); // Create the codecs object to save and load annotations var codecs = new Leadtools.Annotations.Core.AnnCodecs(); // Save the container var xmlData = codecs.save(container, Leadtools.Annotations.Core.AnnFormat.annotations, null, 1); // delete the container container = null; // Show information about the data we just saved var info = codecs.getInfo(xmlData); var message; if (info.get_format() == Leadtools.Annotations.Core.AnnFormat.annotations) { message = "Version: "; message += info.get_version(); message += " No. of pages: "; message += info.get_pages().length; message += " page nos: "; for (var i = 0; i < info.get_pages().length; i++) { message += info.get_pages()[i] + " "; } } else { message = "Invalid annotations data"; } alert(message); // Load the container we just saved container = codecs.load(xmlData, 1); // Show it this.showContainer("After load", container); }, showContainer: function SiteLibrary_DefaultPage$showContainer(message, container) { var str = message + "\nContainer size: "; // Add the size var inch = 720; var width = container.get_size().get_width() / inch; var height = container.get_size().get_height() / inch; str += width + " by " + height + " inches" + "\n"; // Add the objects str += "Contains " + container.get_children().get_count() + " objects(s)\n"; for (var i = 0; i < container.get_children().get_count(); i++) { var annObj = container.get_children().get_item(i); str += "Object: " + annObj.get_friendlyName() + " at "; for (var j = 0; j < annObj.get_points().get_count(); j++) { var pt = annObj.get_points().get_item(j); var x = pt.get_x() / inch; var y = pt.get_y() / inch; str += "(" + x + ", " + y + ") "; } str += "\n"; } alert(str); },
