In the technical scheme provided by the embodiment of the invention, the terminal can be a Personal Computer (PC) or a mobile terminal. The PC may be a PC of a windows operating system, a PC of a vista operating system, or the like. For the mobile terminal, the terminal may be a terminal of an android system, a terminal of an IOS operating system, a terminal of a saiban system, and the like.
Embodiments of the present invention are further described below with reference to specific application scenarios.
Take a PC of a windows operating system (hereinafter abbreviated as windows PC) and a mobile terminal of an android system (hereinafter abbreviated as android terminal) as examples.
The web server (here, taking FTP server as an example) first determines whether the manuscript to be annotated is in a picture format, and if the manuscript is not in the picture format, the manuscript is converted into a picture in page units (which may not be in page units and is set according to the user's requirements), and the picture is used as the original picture of the annotation tool. Of course, the above-mentioned judgment of whether the annotated manuscript is a picture or not, and if not, the action of converting the manuscript into a picture can be executed by the terminal.
The Windows PC user clicks the button of the annotation tool on the page (taking Windows annotation tool as an example, a core module in the annotation tool externally discloses a MarkWnd class, which is an external interface of the core module.
The user can annotate on the artwork, and the windows PC identifies the selected annotation symbol by the user clicking on the button of the annotation symbol on the annotation tool. When a user clicks or lifts a mouse on an original image, an object ONLButton-Down or ONLButtonUp in the MarkWndImple-like is triggered, the two objects are directly connected with each annotation controller, the annotation controller creates annotation symbols, the size, the shape, the outline, the behavior and the like of the annotation symbols are given, and finally the annotation symbols are drawn. For example, windows PC provides a set of methods for drawing pictures: CGraphSys (graphics system class). Drawing of some basic elements (e.g., straight lines, rectangles, ellipses, etc.) can be performed by this drawing method. The CGraphSys has two sets of coordinate systems, a display coordinate system and a world coordinate system. As with their names, the display coordinate system represents the location of a particular point on the screen, using pixel counts, the display coordinate system can accurately locate the location of a pixel point on the display device; the world coordinate system may represent the actual size, regardless of the display device, in millimeters (e.g., line width of a line, length of a line, etc.). Meanwhile, the CGraphSys provides a method for mutual conversion of two sets of coordinate systems.
And the Windows PC stores the annotated information as an XML file, and stores the XML file in the FTP server in a way of being associated with the original image by calling an interface of the FTP server. The screenshot of the endorsement information after the Windows PC endorsement can also be stored in the FTP server.
An android terminal user clicks a button of the annotation tool on a page, the android terminal identifies the action of the user clicking the button of the annotation tool, the annotation tool is opened, and the XML file and the original image of the windows PC with the annotation information are obtained by calling an FTP server interface.
And the android terminal analyzes the obtained XML file and the original image, and draws the XML file and the original image so as to be correctly displayed on an interface of the annotation tool. The core of the android terminal mobile annotation drawing is a drawing thread and a gesture recognizer (the gesture recognizer can recognize the touch action of a user on a touch screen of the android terminal), the drawing thread draws a packaged annotation note object on an original image in a traversing manner, and the annotation note object is an object corresponding to information (freehand information, text information or picture information) stored in an XML file. The attribute information in the android terminal comprises dot matrix coordinates of the hand-drawn information, creation time, annotation time, error types, revisers, revision time, line width, annotation categories, ID, punctuation areas (the punctuation areas are formed by position coordinates of the current annotation information in an original drawing, the coordinates are stored in the data domain of the annotations and are distributed to the punctuation areas, and the coordinates can be used for judging whether the next annotation is revised for the current annotation) and the like; for the annotation with characters along with the hand painting, the attribute information also comprises a UTF-8 code for inserting the characters, a text area array (the text area is formed by position coordinates of the inserted characters in the original image), and the like; for the hand-drawn annotation of the band diagram, the attribute information further includes a picture BASE64 code, a picture area matrix (which is made up of position coordinates of the outer border of the inserted picture in the original drawing), and the like.
And the android terminal user utilizes the annotation tool to modify the annotations made by the windows PC user or add new annotations, and the like, stores the annotation information as an XML file, and then stores the XML file in the FTP server in association with the original image.
