An ImageMap allows you to attach URLs to specific areas, called hotspots, on a picture in your document. An image map is a group of one or more hotspots.
You can draw three types of hotspots: rectangles, ellipses, and polygons. When you click a hotspot, the URL is opened in the browser window or frame that you specify. You can also specify the text that appears when your mouse rests on the hotspot.
Position the cursor where you want the ImageMap in your document.
நுழை - பிம்பம் ஐத் தேர்ந்தெடு, ஒரு பிட்டுபடத்தைத் தேர்ந்து,நுழைத்திடுக.
With the image selected, choose Edit - ImageMap in Writer and Calc or Tools - ImageMap in Impress and Draw. You see the ImageMap Editor, which displays the image at the background.
Use the icons in the ImageMap Editor to draw a hotspot shape, for example a rectangle, over the image at the background.
You can see an extended help text on the functions of each icon when you enable Extended Help in LibreOffice - PreferencesTools - Options - LibreOffice - General.
Enter the "Address" URL that will be shown in a Web browser when the user clicks the hotspot.
Optionally, enter the "Text" that will be shown as a tip when the user points the mouse to the hotspot.
Click the Apply button to apply your changes, and close the ImageMap Editor.
Save the document in the LibreOffice or HTML format.
You may save the ImageMap as a file and upload that file to a Web server, for example.
