Use the bounding box tool to draw boxes around each line of text:

1. Draw a rectangle using your mouse over each line of text
2. Make sure the box covers all of each line and, leave a 2 - 3 pixel margin
3. If lines are overlapping, draw a box around each object, include all contiguous parts the lines in their respective boxes.
4. Do not include parts of the line that cannot be seen, even though you think you can interpolate the whole shape of the target.
5. If the line goes off the screen, label up to the edge of the image.
