Introduction

This application demonstrates the functionality of a mosaic image generation using OpenGL. It takes in an input image and generates a 2x2 mosaic of that image.

Supported plaforms

Platform	Linux x86_64	Linux+RTOS mode	QNX+RTOS mode	SoC
Support	NO	YES	YES	J721e / J721S2 / J784S4 / J742S2 / J722S

Steps to run the application

1. Build the application and related libraries as mentioned in Build Instructions
2. The input file comes from "${VX_TEST_DATA_PATH}/test_data/psdkra/app_opengl_mosaic/input1_file.bin"
3. In Linux+RTOS or QNX+RTOS mode
   1. VX_TEST_DATA_PATH environment variable is set as part of vision_apps_init.sh
   2. Run the app as shown below on the J7 EVM target

      cd /opt/vision_apps
      source ./vision_apps_init.sh
      ./vx_app_arm_opengl_mosaic.out

4. The output mosaic image will be output to a file called "mosaic_output_file.bin" at the location "/opt/vision_apps/test_data/output/".
5. The output image is in RGB format with dimensions 1920x1080. It can be viewed with an image viewer that supports this file format, such as 7YUV.
