Configuration & Usage

Configuration Setup​

After installation, the configuration file VxConfig.conf and VxExposure.yaml will be located at:

/vizionsdk_c-{version}-{os}/bin/VxConfig.conf
/vizionsdk_c-{version}-{os}/bin/VxExposure.yaml

This configuration file allows vizionsdk_c to recognize TechNexion series camera devices.

If you haven’t installed the native VizionSDK library, please set the VIZIONSDK_CONFIG_PATH environment variable as shown below:

  1. Windows
    • PowerShell: 
      $env:VIZIONSDK_CONFIG_PATH = "path\to\vizionsdk_c-{version}-{os}\bin"
    • Command Prompt (CMD): 
      set VIZIONSDK_CONFIG_PATH=path\to\vizionsdk_c-{version}-{os}\bin
  2. Linux 
    export VIZIONSDK_CONFIG_PATH=/path/to/vizionsdk_c-{version}-{os}/bin
info

Alternatively, you can place the VxConfig.conf and VxExposure.yaml files in the same directory as your executable.

How to use vizionsdk_c​

You can link the vizionsdk_c library with CMake. For more details, see the Sample Build Guide.

Prerequisites​

  • CMake (version 3.0 or newer)
  • C compiler

Import the library​

Add the vizionsdk_c header in your code:

#include "vizionsdk.h"

Build the project with CMake​

Link vizionsdk_c library from the extracted folder, update the paths manually:

# Set path to the vizionsdk_c library directory
# NOTE: Update this path to match your vizionsdk_c location
set(VIZIONSDK_C_PREFIX <your_vizionsdk_c_path>)

list(APPEND CMAKE_PREFIX_PATH ${VIZIONSDK_C_PREFIX})
find_package(vizionsdk_c REQUIRED)

target_include_directories(${PROJECT_NAME}
  PRIVATE
  ${VIZIONSDK_C_INCLUDE_DIR}
)

# Link libraries
target_link_libraries(${PROJECT_NAME}
  PRIVATE
  vizionsdk_c::vizionsdk_c
)
info

vizionsdk_c automatically links to VizionSDK if it is available in the system PATH.
If not found, it will link to the native library located in the same directory as vizionsdk_c.

For more detailed information and advanced usage, please refer to the API documentation or the examples on GitHub.
