====== Add an image ======

It is possible to add an **image along the distance axis**
to enrich the readability of the Time-Location schedule.

This feature can be used, for example, to display:

  * an orthophoto
  * a project plan
  * an infrastructure diagram
  * a map background

The image is then displayed **directly below the schedule**
and aligned with the distance axis.

===== Add an image line =====

In the **Distance axis** tab, click **+** to add
a new line.

Then select the **Image** type.

Click **Import image** to load the image to display.

-----

===== Position the image along the project =====

An image is positioned on the schedule using two values:

  * **Value 1**: starting chainage
  * **Value 2**: ending chainage

These two reference points define the **portion of the project covered by the image**.

The image is automatically **stretched between these two points**
so that it matches the real distance of the project.

-----

===== Adjust the display =====

Several parameters allow the image display to be adjusted:

  * **Line height**  
  defines the height of the image band

  * **Fixed ratio**  
  preserves the proportions of the image

These settings help adapt the image to the readability
of the schedule.

-----

Using images allows you to add **visual geographical context**
to the Time-Location schedule and improves
the understanding of the project.
