No matter what your image processing needs are, LEADTOOLS has the world's leading SDK to complete all the heavy work. In previous articles, we discussed viewing images, saving images, combining images into one file, and splitting one file into multiple images. LEADTOOLS can also draw and edit annotations and markup objects on the image.
In today's world full of digital collaboration and image sharing, comprehensive annotation support is essential. People and organizations use various types of annotations throughout the day to draw attention to specific aspects of images or documents and enhance user experience, productivity, and security. The LEADTOOLS annotation library supports marking objects and tools, including highlighting, referring to drawings, adding annotations, making measurements, redacting or underlined text, and more powerful collections.
The code below will help you get started, or you can always check out our complete tutorial on graphical annotations. We will also explain how to create custom annotations for your documents or images.
private void Form1_Load(object sender, EventArgs e)
{
// Initialize Image Viewer object
viewer = new ImageViewer();
viewer.Dock = DockStyle.Fill;
// Initialize Automation Control for Image Viewer
automationControl = new ImageViewerAutomationControl();
automationControl.ImageViewer = viewer;
// Initialize a new RasterCodecs object
RasterCodecs codecs = new RasterCodecs();
// Load the main image into the viewer
viewer.Image = codecs.Load(@"C:\LEADTOOLS21\Resources\Images\ocr1.tif");
// Initialize the Interactive Mode for the Image Viewer
AutomationInteractiveMode automationInteractiveMode = new AutomationInteractiveMode();
automationInteractiveMode.AutomationControl = automationControl;
// Add the Interactive Mode to the Image Viewer
viewer.InteractiveModes.BeginUpdate();
viewer.InteractiveModes.Add(automationInteractiveMode);
viewer.InteractiveModes.EndUpdate();
if (viewer.Image != null)
{
// Create and set up the Automation Manager
annAutomationManager = new AnnAutomationManager();
annAutomationManager.RestrictDesigners = true;
// Instruct the Manager to create all the default Automation objects.
annAutomationManager.CreateDefaultObjects();
// Initialize the Manager Helper and create the Toolbar
// Add the Toolbar and the Image Viewer to the Controls
AutomationManagerHelper managerHelper = new AutomationManagerHelper(annAutomationManager);
managerHelper.CreateToolBar();
Controls.Add(managerHelper.ToolBar);
Controls.Add(viewer);
// Set up the Automation (it will create the Container as well)
automation = new AnnAutomation(annAutomationManager, automationControl);
// Set this Automation as the active one
automation.Active = true;
// Set the size of the Container to the size of the Image Viewer
automation.Container.Size =
automation.Container.Mapper.SizeToContainerCoordinates(LeadSizeD.Create(viewer.Image.ImageWidth,
viewer.Image.ImageHeight));
