Use the Image > Burn In Info command, to burn additional information, such as the scale bar or the info stamp into the active image. Measurement data can also be burnt into the image in this way.
What exactly does it mean to burn something in?
When you burn in information, you write this additional information irrevocably into the image. This additional information will then become an integral part of the image. All of the pixels that lie beneath the additional information displayed on the image, e.g., beneath the scale bar, will be overwritten by the burning in. In this way, image information will, of course, be lost.
When you burn in image information, please pay attention to the points listed below:
Which information will be burnt in?
All of the additional information that is on display on your monitor when you use the above command, will be burnt in. This means that a scale bar will only be burnt in when it is on display at that time.
How will the information be burnt in?
Please note that additional information will not always be burnt into an image in the size it is displayed on your monitor.
When you burn in a scale bar, its length will be automatically adapted to match the image. Where a very large image is concerned, the scale bar you burn in will be correspondingly longer than with a smaller image.
The information in the info stamp is burned into the image exactly as it appears in the image window when the whole image is displayed in the image window. To do so, click the Fit to Window button on the Zoom toolbar. This guarantees that the information will be visible even with very large images.
Converting an image type when burning in information
When you burn additional information into an image, this is often only possible when in this process, the image type is changed. For example, you can't burn colored labeling into a gray-value image, without either turning the image into a colored one, or setting the color of the writing at one or the other gray value.
Loss of data by burning in
By burning information into an image you will, in every case, lose image data, namely the data that lies beneath the information that you burn in.
You may, however, lose still more data, owing to the automatic conversion of the image type, that occurs. For example, a 16-bit gray-value image will be automatically converted into a 24-bit true color image by the burning in. In this case, the image contains considerably less data but nevertheless still looks the same in the image window.
Time stacks
Where time stacks are concerned, the additional information will be burnt into every frame.
A time stack is then still a time stack. However, the burning in process converts every frame in the time stack into a 24-bit true-color image.
When you burn in the info stamp: The relevant acquisition time will be burnt into each frame.
