The Image Editor allows you to create your own image and text and then display it on your NXTs display screen. You can also edit existing image files.
The editing screen displays the exact number of pixels featured on the NXT display: 100 pixels wide by 64 pixels high. The Image Editor opens four types of formats: .ric, .jpg, .png, and .bmp.

What you need to do
The editing process has 3 steps:
- Click on Open to select and import an existing image file from your computer or use the tool palette to begin creating your own image from scratch.
- Edit the image using the tool palette to the left of the editing screen.
- Save the file on your computer.
Importing an image file
- 1. Choose an image to edit by browsing through your computer. By default, the program opens the Image folder in the LEGO® MINDSTORMS® Software.
- 2a. Crop the section of the image you want to use by zooming in and out and pan the image by clicking and dragging it.
- 2b. Set the level of detail you want displayed using the threshold slider.
- 3. The editing screen features the same number of pixels as the NXT display screen, so any image you edit or create will always fit the display on the NXT.
- 4. The Preview window will let you see your image exactly as it will be shown on the NXT display.

TIP: How to save in other formats
The NXT software automatically saves all images using the .ric extension. To save an image file in another format, manually change the extension using .jpg or .png after the file name. For example, if the image file is saved as "smile.ric", simply change the .ric extension to "smile.jpg" or "smile.png" and click Save to change the format.
