Text Roi

[Abdul Muqeet Khan]

I am using text annotation and drawing some text on the image. Problem
 is when i am saving the text roi and trying to load it again it shows
 the rectangle roi instead of the text. Firstly does the text gets stored
 in the .roi file and if yes what i need to do if i would like to
 reload it on the image.
   
  Thanks in advance

Without using the text roi how could one write/draw text on the image. Can i use
imp.getProcessor().drawString("TEXT", x, y);  but this doesn't work.

When the user clicks on the image canvas i open a dialog box and asks the user to enter the text. I have the text and would like to draw this text on the image. Using text roi is the text in a rectangle, and looks its not simple doing in this way.

Help is needed. Thanks in advance

problem by using macros. For example, here is a macro tool that
replaces the built in text tool.

    // This tool draws text when the user
    // clicks on the image. Double click on
    // the tool icon to change the text.
     var size = 18;
     var text = "This is some text";
     macro "Text Tool - C00fT4e16T" {
         getCursorLoc(x, y, z, flags);
         setFont("SansSerif", size, "bold");
         drawString(text, x, y);
     }
     macro "Text Tool Options" {
         text = getString("Text: ", text);
     }

Rois gets flickered when i say updateAndDraw() after drawString. I m doing in this way
  class ImageCanvas
   
  showAllROIs(Graphics g) {
  ....
  ...
  if(textRoi) {
  imp.getProcessor().drawString("ImageJ", roi.x, roi.y);
  imp.updateAndDraw();
  } else {
  drawRoi(g, roi, i);
  }
   
  Thanks in advance

You have to also update the display using imp.updateAndDraw().
