Overview

This example shows how to create and use images. The following use cases have been implemented in this example:

  • Draw a .PNG image with transparency, pre-generated during the application build
  • Draw a .PNG image without transparency, pre-generated during the application build
  • Draw a .PNG image with transparency, decoded at runtime (using the runtime PNG decoder)
  • Draw a .PNG image without transparency, decoded at runtime (using the runtime PNG decoder)

Requirements

  • MICROEJ SDK 6.
  • A VEE Port that contains:
    • EDC-1.3 or higher.
    • BON-1.4 or higher.
    • MICROUI-3.4 or higher.

This example has been tested on:

Usage

Follow MICROEJ SDK 6 Installation Guide to setup the SDK.

By default, the sample will use the NXP i.MX RT1170 VEE Port 3.0.0. The sample retrieves the VEE Port as a module.

Refer to the Select a VEE Port documentation to use another VEE Port in your project.

Configuration

Configuration options can be found in: configuration/common.properties.

The images heap size has been set to 500kB for the PNG images runtime decoding.

Run on Simulator

Run the following command in your IDE (or click the Play button next to the line below when opening this README in IntelliJ IDEA):

./gradlew :microui.image:runOnSimulator

Alternative ways to run in simulation are described in the Run on Simulator documentation.

Run on Device

Complete the Getting Started for NXP i.MX RT1170 Evaluation Kit to make sure your environment is fully setup.

If you are using another VEE Port, make sure to properly setup the VEE Port environment before going further. Refer to the dedicated VEE Port README or Getting Started for more information.

Run the following command in your IDE (or click the Play button next to the line below when opening this README in IntelliJ IDEA):

./gradlew :microui.image:runOnDevice

Alternative ways to run on device are described in the Run on Device documentation.

Expected Behavior

The images stored in src/main/resources/images are displayed on the screen.

Dependencies

The dependencies defined in build.gradle.kts are configured in libs.versions.toml.

All dependencies are retrieved transitively by Ivy resolver.
