Field Documentation

◆ burst_recorded

uint8_t burst_recorded

If non-zero, this image was captured during a Burst Record operation.

◆ channel_mode

AxChannelMode channel_mode

Channel selected (single channel, vector sum, interleaved channels.

◆ data_type

AxDataType data_type

Data type (signed or unsigned, 8-, 16-, or 32-bits, big endian or little endian, etc.

◆ force_trig

uint8_t force_trig

If non-zero, image_sync trigger is too slow; image was force-triggered.

Examples
AxsunOCTCapture_example.c.

◆ height

int32_t height

Height (pixels).

◆ image_number

uint32_t image_number

Unique image number. A value of zero indicates a force-triggered image.

Examples
AxsunOCTCapture_example.c.

◆ last_packet_metadata

axpacket_t last_packet_metadata

Packet metadata for the last packet in this image (for internal use).

◆ pipeline_mode

AxPipelineMode pipeline_mode

Pipeline mode (raw data, windowed, log compressed, JPEG compressed, etc.

◆ shift_adj

uint8_t shift_adj

Dynamic range adjustment for conversion of pixel values into physical units (e.g. volts).

◆ size_bytes

uint32_t size_bytes

Total image size (bytes): the required size of a buffer allocated by the user for image retrieval using axRequestImageAdv() or axRequestImage(), assuming no cropping or JPEG downsampling is requested.

◆ subsampling_factor

uint8_t subsampling_factor

The subsampling factor used during capture of this image.

◆ test_vector_data

uint8_t test_vector_data

If non-zero, this image's data source is FPGA test vectors, not sampled ADC data.

◆ time_stamp

struct axtimeval_t time_stamp

Image acquisition time stamp in UNIX Epoch time (seconds since 00:00:00 UTC on 1 Jan 1970).

◆ trig_too_fast

uint8_t trig_too_fast

If non-zero, image_sync trigger is too fast; image width possibly affected by missed trigger.

Examples
AxsunOCTCapture_example.c.

◆ width

int32_t width

Width (pixels).

Examples
AxsunOCTCapture_example.c.
