RoboRealm Server API - COM functions

The following COM functions are examples on how to use the provided COM object to execute certain functions against the RoboRealm API Server. Note that the function references are provided in CSharp format. When used in other languages you may have to check that language's capabilities for object passing. All provided examples assume that a connection has already been made to the RoboRealm API Server using something akin to: 


using RR_COM_APILib;

private const int VARIANT_TRUE = -1;
private const int VARIANT_FALSE = 0;

RR_COM_APILib.API_Wrapper rr = new API_Wrapper();

if (connection.Startup() == VARIANT_TRUE)
{
 ....
}
In other languages

set rr=CreateObject("RoboRealm.API.1")

if rr.Startup() <> 0 then
  ....

  rr.Disconnect()
end if
may be sufficient.

SetCOMType - Switches between API and DLL

The API (network connection to RoboRealm server) and the DLL (incorporate RoboRealm within your application) can be accessed using the same function calls mentioned here. It is normally best to start application integration using the API since the calls to RoboRealm can be made visible (assuming RoboRealm is used in GUI mode). Once the integration is complete, once can switch to using the DLL using the SetCOMType which will move the access type from the network based API to loading in the RoboRealm DLL instead. 

SetComType ( [input]0 or 1 )


rr.SetCOMType(1) ' sets the calls to use DLL instead of API.

Startup - Starting and connecting to RoboRealm

This request will attempt to connect to the RoboRealm API. If it fails, it will attempt to start the RoboRealm application with the API enabled. If that fails an error is returned. Note this uses registry information to determine where the RoboRealm.exe is stored. 

Startup ( )

return
	VARIANT_TRUE on success

if (rr.Startup()==VARIANT_TRUE)
{
...
}

Open - Starting RoboRealm

Creates a new RoboRealm program instance given the specified path. This is useful if you want better control over starting RoboRealm.exe from a specific folder. 

Open ( [input]filename, [input]port )

parameters
	filename - the RoboRealm.exe path/filename needed to create a new instance
	port - API port to use (typically 6060)

return
	VARIANT_TRUE on success

if (rr.Open("c:\\Program Files (x86)\\RoboRealm\\RoboRealm.exe", 6060)
	==VARIANT_TRUE)
{
	if (rr.Connect("localhost", 6060)==VARIANT_TRUE)
	{
	...
	}
}

OpenEx - Starting RoboRealm

Simliar to Open but adds an additional parameter to pass arguments to the RoboRealm.exe program. See API Parameters for what parameters are valid. 

OpenEx ( [input]filename, [input]args, [input]port)

parameters
	filename - the RoboRealm.exe path/filename needed to create a new instance
	args - program parameters (typically "-faceless")
	port - API port to use (typically 6060)

return
	VARIANT_TRUE on success

if (rr.OpenEx("c:\\Program Files (x86)\\RoboRealm\\RoboRealm.exe", 6060, "-faceless")
	==VARIANT_TRUE)
{
	if (rr.Connect("localhost", 6060)==VARIANT_TRUE)
	{
	...
	}
}

Connect - Connecting to RoboRealm

Opens a network connection to the RoboRealm API. If this fails, check that you have enabled the RoboRealm API by going to RoboRealm Interface->Options Button->API tab. 

Connect ( [input]hostname, [input]port )

parameters
	hostname - the machine name where RoboRealm is located
		(typically 'localhost' or '127.0.0.1')
	port - API port to use (typically 6060)

return
	VARIANT_TRUE on success

if (rr.Open("c:\\Program Files (x86)\\RoboRealm\\RoboRealm.exe", 6060)==VARIANT_TRUE)
{
	if (rr.Connect("localhost", 6060)==VARIANT_TRUE)
	{
	...
	}
}

IsConnected - Indicates active connection

Returns true or false depending on if an active connection is currently connected to RoboRealm. 

IsConnected ( )

return
	true - a good connection is currently present
	false - connection lost


if (!rr.IsConnected())
{
	if (rr.Connect("localhost", 6060)==VARIANT_TRUE)
	{
	...
	}
}

SetTimeout - Sets connection timeout

Sets the network connection timeout parameter. This is by default set to 30 seconds (30000) but this can be too long or short if your connection tends to fail. If you connection to RoboRealm fails the timeout specifies how long the API will wait until it determines the connection to have failed. 

SetTimeout ( [input] timeout_ms )

return
	timeout_ms - milliseconds to wait on any connection to the API server


rr.SetTimeout (1000);

SetAutoReconnect - Sets reconnection mode

If a connection is lost to RoboRealm, the COM object will attempt to reconnect and issue the same request. If your connection also requires initialization to setup a known state in RoboRealm you will want to DISABLE this and instead use the IsConnected function to determine network connection failure such that you can re-connect and then initialize the state as needed. 

SetAutoReconnect ( [input] true_false )

return
	true - attempt to reconnect if a connection fails
	false - do not attempt to automatically reconnect


rr.SetAutoReconnect (false);

GetDimension - Getting the current image dimensions

This request will return the dimensions of the source, processed or a specified marked image. Note that these dimensions can be different from the camera dimensions due to usage of modules like scaling or cropping. To get the current camera width and height see get_camera_format below.

GetCameraProperties - Getting the active camera's image capture properties

Gets the properties for the current camera using DirectX. Note that not all properties are supported by each camera. The returned list will be of those properties that DirectX reports as being functional. Despite this the list may still contain properties that do not have any effect on the camera.

Note that you can include only those properties that you wish to query in the request list. If no properties are specified then all property values are returned. 

GetCameraProperties ( [output] names, [output] values, [output] min, [output] max,
		[output] automatic, [input]num )

parameters
	names - will contain the list of property names
	values - will contain the list of current property values
	min - value minimums
	max - value maximums
	automatic - indicates if value is automatically determined


object names;
object values;
object min;
object max;
object automatic;
int num = rr.GetCameraProperties(out names, out values, out min, out max, out automatic, 64);

Run - Enable/Disable Processing

This request provides a way to stop processing incoming video. Some image processing tasks can be very CPU intensive and you may only want to enable processing when required but otherwise not process any incoming images to release the CPU for other tasks. The run mode can also be used to processing individual frames or only run the image processing pipeline for a short period. This is similar to pressing the "run" button in the main RoboRealm dialog. 

Run ( mode )

parameters
	mode - can be "toggle", "on", "off", "once", or a number of frames to process

rr.Run("Off");

Pause/Resume - Processing

The following request can be used to pause the RoboRealm pipeline processing. This is most useful if you need to query several variables in different requests that are dependent on each other. For example, you may request a variable with the length of another array variable. By pausing, reading, and then resuming the processing you can be sure that the variables are related to each other correctly and that a new value has not been created or an old one changed.

Note that once paused the application will appear to have locked. You must ensure to follow a pause with a resume command or restart the RoboRealm application to continue normal processing. 


Pause ()

Resume ()



rr.Pause()

rr.Resume()

WaitVariable - Waiting for RoboRealm

There is often a need to pause your own Robot Controller program to wait for RoboRealm to complete its task. The easiest way to accomplish this is to wait on a specific variable that is set to a specific value by RoboRealm. Using the wait_variable request you can pause execution and then continue when a variable changes within RoboRealm. 

WaitVariable ( var_name, var_value, timeout )

parameter

	var_name - name of the variable to wait for
	var_value - the value of that variable which will cancel the wait
	timeout - the maximum time to wait for the variable value to be set


rr.WaitVariable("IMAGE_COUNT", "100", 10000);

WaitImage - Waiting for a new image

If you are rapidly grabbing images you will need to wait inbetween each get_image for a new image to be grabbed from the video camera and processed. The waitImage request ensures that a new image has been processed and is available to grab. Without this routine you may be grabbing the same image more than once. 


WaitImage ( )

WaitImageFor ( timeout )


rr.WaitImage();

rr.WaitImage(2000);

EditModule - Editing a module

This request allows you to cause RoboRealm to display the GUI interface for a specific module. This works even when in faceless mode and allows your application to leverage the interfaces within RoboRealm without needing to recode what already exists. 

EditModule ( [input] name, [input] count )

parameters
	module_name - the name of the module to enable (eg RGB_FILTER)
	module_count - which module to reference in case you have
		more than one module of the same name (i.e. two Color_Filter modules).


rr.EditModule("RGB_Filter", 1);

EditModuleAtLine - Editing a module

This request allows you to cause RoboRealm to display the GUI interface for a module on the specified line number. This works even when in faceless mode and allows your application to leverage the interfaces within RoboRealm without needing to recode what already exists. 

EditModuleAtLine ( [input] line_number )

parameters
	line_number - the line number of the module to delete (eg 12)


rr.EditModuleAtLine(12);

MinimizeWindow - Minimizing RoboRealm Interface

The following request minimizes the RoboRealm interface such that it disappears into the task bar. 

MinimizeWindow

rr.MinimizeWindow();

MaximizeWindow - Maximizing RoboRealm Interface

The following request maximizes the RoboRealm interface such that it takes up the full screen. 

MaximizeWindow

rr.MaximizeWindow()

ResizeWindow - Resizing the RoboRealm Interface

The following request resizes the RoboRealm interface. Note that you can resize the interface below the recommended size where the interface can become mostly be unusable. 

ResizeWindow ( [input]width, [input]height )

parameters
	width - the width to set the RoboRealm GUI Interface
	height - the height to set the RoboRealm GUI Interface

rr.ResizeWindow(1024, 768);

MoveWindow - Moving the RoboRealm Interface

The following request moves the RoboRealm interface to a new location. Note that you can move the interface offscreen such that the user will not see the interface but will still know it is running as shown by the task bar. 

MoveWindow ( [input]X, [input]Y )

parameters
	X - horizontal location to set the top right of the RoboRealm Interface
	Y - vertical location to set the top right of the RoboRealm Interface

rr.MoveWindow(0, 0);

PositionWindow - Moving and Resizing the RoboRealm Interface

The following request moves and resizes the RoboRealm interface in one command. 

PositionWindow ( [input]X, [input]Y, [input]width, [input]height )

parameters
	X - horizontal location to set the top right of the RoboRealm Interface
	Y - vertical location to set the top right of the RoboRealm Interface
	width - the width to set the RoboRealm GUI Interface
	height - the height to set the RoboRealm GUI Interface

rr.PositionWindow(0, 0, 400, 400);

ShowWindow - Showing and Hiding the RoboRealm Interface

The following request will hide the RoboRealm interface 

ShowWindow ( [input] true|false )

parameter
	true|false - indicates if the main RoboRealm window show be hidden(false) or shown(true)

rr.ShowWindow(false);

EnterKiosk - Enter/exit Kiosk mode

The following request will enter/exit the Kiosk mode 

EnterKiosk ( [input] true|false )

parameter
	true|false - indicates if Kiosk mode should be activated(true) or exited(false)

rr.EnterKiosk(true);

Disconnect - Terminate API Connection

The following request will terminate the current API connection to the RoboRealm server BUT leave the RoboRealm application running. Any subsequent API commands will NOT work as the connection will have been terminated. For example, if you Disconnect and then Close the application will NOT Close since you have already terminated the API connection before the Close command was issued. In this case, just issuing a Close will accomplish the desired result. 

Disconnect ( )

rr.Disconnect()

Close - Exit RoboRealm Application

The following request closes RoboRealm in a nice manner. If you are running RoboRealm on the same machine that your API program is located you can use the "open" routine to start the RoboRealm process and this close request to terminate the application. Note this will also terminate the API connection since you are requesting the server to exit. 

Close ( )

rr.Close()

GetVersion - RoboRealm Version Number

This request returns the current version of RoboRealm running. This is a good test to see if the API is enabled as it is one of the most simplest API calls with the fewest dependencies on cameras, pipeline, etc. 

GetVersion

return
	Current RoboRealm Version X.Y.Z


Console.WriteLine(rr.GetVersion());
