Class
AravisCamera
Description [src]
class Aravis.Camera : GObject.Object
implements Gio.Initable {
/* No available fields */
}ArvCamera is a class for the generic control of cameras. It hides the complexity of the genicam interface
by providing a simple API, with the drawback of not exposing all the available features. See ArvDevice
and ArvGc for a more advanced use of the Aravis library.

arv_camera_get_chunk_mode
Check wether chunk data mode is active. Please see arv_camera_set_chunk_mode().
since: 0.8.0
arv_camera_get_chunk_state
Gets state of chunk data. Chunk data are be embedded in ArvBuffer only
if chunk mode is active. Please see arv_camera_set_chunk_mode().
since: 0.8.0
arv_camera_get_device
Retrieves the ArvDevice object for more complete access to camera features.
since: 0.2.0
arv_camera_get_payload
Retrieves the size needed for the storage of an image. This value is used for the creation of the stream buffers.
since: 0.8.0
arv_camera_get_trigger_source
Gets the trigger source. This function doesn’t check if the camera is configured to actually use this source as a trigger.
since: 0.8.0
arv_camera_get_x_binning_bounds
Retrieves the valid range for image horizontal binning.
since: 0.8.0
arv_camera_gv_auto_packet_size
Automatically determine the biggest packet size that can be used data streaming, and set GevSCPSPacketSize value accordingly. This function relies on the GevSCPSFireTestPacket feature. If this feature is not available, the packet size will be set to a default value (1500 bytes).
since: 0.8.0
arv_camera_gv_select_stream_channel
Select the current stream channel. Negative channel_id is ignored.
since: 0.8.0
arv_camera_gv_set_ip_configuration_mode
Sets the IP address configuration mode. Available modes are ARV_GV_IP_CONFIGURATION_MODE_DHCP, ARV_GV_IP_CONFIGURATION_MODE_PERSISTENT_IP, ARV_GV_IP_CONFIGURATION_MODE_LLA.
since: 0.8.22
arv_camera_gv_set_packet_delay
Configure the inter packet delay to insert between each packet for the current stream
channel. This can be used as a crude flow-control mechanism if the application or the network
infrastructure cannot keep up with the packets coming from the device. Negative delay_ns is ignored.
since: 0.8.0
arv_camera_gv_set_packet_size
Specifies the stream packet size, in bytes, to send on the selected channel for a GVSP transmitter or specifies the maximum packet size supported by a GVSP receiver.
since: 0.8.0
arv_camera_gv_set_packet_size_adjustment
Sets the option for packet size adjustment that happens at stream object creation.
since: 0.8.3
arv_camera_gv_set_stream_options
Sets the options used during stream object creation. These options mus be set before the call to arv_camera_create_stream().
since: 0.6.0
arv_camera_set_access_check_policy
Sets the feature access check policy. When enabled, before being accessed, the actual read/write access of register is checked using AccessMode properties. On some devices, it helps to avoid forbidden writes to registers that may put the device in a bad state.
since: 0.8.22
arv_camera_set_binning
Defines binning in both directions. Not all cameras support this
feature. Negative dx or dy values are ignored.
since: 0.8.0
arv_camera_set_chunk_mode
Controls wether chunk data mode is active. When active, chunk data
are appended to image data in ArvBuffer. A ArvChunkParser must be used in
order to extract chunk data.
since: 0.8.0
arv_camera_set_chunk_state
Sets state of a chunk data. Chunk data are be embedded in ArvBuffer only
if chunk mode is active. Please see arv_camera_set_chunk_mode().
since: 0.8.0
arv_camera_set_chunks
Convenience function for enabling a set of chunk data. Chunk mode is activated, or deactivated
if chunk_list is NULL or empty. All chunk data not listed are disabled.
since: 0.8.0
arv_camera_set_exposure_time
Sets exposure time. User should take care to set a value compatible with
the desired frame rate. Negative exposure_time_us is ignored.
since: 0.8.0
arv_camera_set_frame_rate
Configures a fixed frame rate mode. Once acquisition start is triggered, the video stream will be acquired with the
given frame rate. A negative or zero frame_rate value disables the frame rate limit.
since: 0.8.0
arv_camera_set_range_check_policy
Sets the feature range check policy. When enabled, before being set, the value of all nodes with an ArvGcFloat or
ArvGcInteger interface will be checked against their Min and Max properties.
since: 0.8.8
arv_camera_set_region
Defines the region of interest which will be transmitted in the video
stream. Negative x or y values, or not strictly positive width or height values are ignored.
since: 0.8.0
arv_camera_set_trigger
Configures the camera in trigger mode. Typical values for source are “Line1” or “Line2”. See the camera documentation for the allowed values. Source can also be “Software”. In this case, an acquisition is triggered by a call to arv_camera_software_trigger().
since: 0.8.0
arv_camera_set_trigger_source
Sets the trigger source. This function doesn’t check if the camera is configured to actually use this source as a trigger.
since: 0.8.0
arv_camera_software_trigger
Sends a software trigger command to camera. The camera must be previously
configured to use a software trigger, using arv_camera_set_trigger().
since: 0.8.0
arv_camera_uv_set_bandwidth
Set the bandwith limit or, if bandwith is not strictly positive, disable the limit.
since: 0.8.0
