With newer versions of the driver new properties will appear without the need to compile the application with new header files. These properties will be registered during the initialization of the device and will vary from device to device. Handles to the properties and methods can be obtained via device specific functions like DMR_FindList() or DMR_CreateSetting().

The complete source code can be found in the examples section: ContinuousCapture.c (for the GenICam interface please refer to ContinuousCaptureGenICam.c instead).įirst the library is initialized and a device is opened:Īpart from the device specific functions which either require a handle to the device itself ( HDEV) or to the devices interface( HDRV) there is a large set of device independent functions to set and read dynamic properties and execute certain functions from GUI applications.

This short section shows how to capture and display a live image together with the output of some statistical information with this interface on Windows®.

These include (among others) functions to capture and access images and functions to load a save settings made for this device. All the functions called for a certain device will start with a leading DMR_. This handle is needed to call most of the other functions interacting with the actual device. Once a device has been initialized the user will receive a handle to the devices interface ( HDRV).

To change device properties using the GenICam interface layout please refer to Changing Device Settings For GenICam-Devices.

Details regarding the interfaces supported by which device Which Interface Is Supported By Which Device?.

Because of this all example applications as well as complex GUI applications like wxPropView will either silently or explicitly switch to the dilGenICam interface layout if possible and the user didn't say otherwise so if an application copies code from example code make sure your application is aware of the interface layout! Further details regarding interface layouts: Since the settings are located at a different position within the property tree off the device, it might cause unexpected behaviour if a property is modified or read based on incorrect assumptions. This will lead to a less extensive feature set. Without setting the interface layout, dilDeviceSpecific will be used by default for all non GenICam devices and all mvBlueCOUGAR-X/XD devices. When the corresponding device has been located, this device can be initialized or closed via calls to the functions DMR_OpenDevice() and DMR_CloseDevice() Note In case of a GenICam compliant device it is important to select the correct interface layout ( dilDeviceSpecific or dilGenICam(recommended)) before opening the device. This function can be called multiple times, but for each time DMR_Init() is called the user must make sure that later, when this library is not needed anymore the function DMR_Close() is called, as otherwise resource leaks will occur.Īfter the library has been initialized successfully (the return value of most of the functions in this module will be an error code), the user can start to locate a certain device by using the function DMR_GetDevice(). Note Please carefully read the detailed description of the DMR_Init() at least once as there are some important things to keep in mind when designing your application! Not doing so might result in severe headache so be warned! Calling this function for the first time will initialize internal data structures and will force the device manager to scan the system for recognized device types. To this the functions DMR_Init() must be used. The standard way of using this library roughly works like this:īefore any device can be accessed the user need to initialize the library. It internally calls the functions described in this interface and will greatly reduce the development time and will result in a more readable code without introducing any disadvantages. The complete C++ interface is available in source code and adds NO relevant overhead to the application. Note If a C++ compiler is available it is highly recommend to work with the C++ interface instead of this C interface as it is much easier to use. This interface represents the basis for the C++ interface but it can also be access with pure C-compilers or from other programming languages that can take advantage of C compliant exported dynamic library functions. This is the documentation for developers who want to work with the C compliant interface of the driver.
