Dear Anchal,
To include such a feature you should customize the Objective-C/Java framework .
You need to implement the image selection yourself based on your requirements.
To add an image attachment, you can use the method Page.AddAnnotAttachment
Code:
page.AddAnnotAttachment("/mnt/sdcard/image.png", 0, new float[]{300,500,330,530})
Code:
/**
* add a file as an attachment to page.<br/>
* you should re-render page to display modified data.<br/>
* this can be invoked after ObjsStart or Render or RenderToBmp.<br/>
* this method require professional or premium license, and Document.SetCache invoked.
* @param path absolute path name to the file.
* @param icon icon display to the page. values as:<br/>
* 0: PushPin<br/>
* 1: Graph<br/>
* 2: Paperclip<br/>
* 3: Tag<br/>
* @param rect 4 elements: left, top, right, bottom in PDF coordinate system.
* @return true or false.<br/>
* the added annotation can be obtained by Page.GetAnnot(Page.GetAnnotCount() - 1), if this method return true.
*/
final public boolean AddAnnotAttachment(String path, int icon, float[] rect)
