The following information on images being acquired or being stored to the recorder container is displayed:

● image size (width/height)
● pixel format
● frame rate (frames/sec)
● line rate (lines/sec)
● data rate (Megabytes/sec)
● delivered buffers
● diagnostic counters for Coaxlink sources:
□ rejected scans: number of scans completely missed (line-scan camera)
□ rejected frames: number of frames completely missed (area-scan camera)
● diagnostic counters for Gigelink sources:
□ lost frames: number of frames completely missed
□ lost packets: number of GigE Vision stream packets missed

Recorder container opened for playback

The following information related to the records stored in the container is displayed:

● timestamp
● pixel format
● image size (width/height)

When you click to enable the pixel component display, the mouse cursor turns into .

As you hover over the image, a small table displays the components of hovered-over pixel, as shown on the screenshots below:

● X/Y: horizontal/vertical position of the pixel on the image
● L: luminance decimal value
● RGB: red/green/blue decimal values
● Offset: pixel position in bytes in the pixel definition table
● Bytes: luminance or RGB expressed in hexadecimal values

With Bayer pixel formats, the offset and bytes values are displayed in two lines as the red, green and blue data are spread in two pixel lines.
