TRACE IMAGE
Use a reference image as a guide

If you need a reference image for your map, for example another map made by someone else, you can use the Trace Image tool to open that reference image as an overlay/background and use it as a guide for your work.


Choose your reference image by clicking on the folder icon (Browse). It will display a new browser window so you can select the image you want to use.

If you want to reset the Trace Image and delete the reference file, click on the arrow icon (Clear).

Once your image is displayed on your map, you can:
Move it by holding click and moving your mouse.
Reset its position by clicking on the Center button.
Change its scale by using the Scale slider or the Mouse Wheel.

Change its opacity with the Opacity slider.

USEFUL INFO
Good to know
At any point in any other tool, you can display or hide the Trace Image by pressing T .
The Trace Image will be displayed over the Water Layer (000) and under the User Layer 1 (100). More info on Layers here.
You can't export your Trace Image with your map. It's built to be used as a guide, not as a background.
If your image isn't displayed, try to use the Clear button and select it again. If that doesn't work, try to save it under a different name and/or format and select it again.
Dungeondraft is working in 256 ppi, so it means each grid square is 256x256 pixels. If your trace image has a different resolution (for example 100 ppi), you can do some simple maths to know the correct scale. For our example here:
256 ppi / 100 ppi = 2.56
. The scale slider of your image will need to be set at 2.56 to be corresponding to your map.
