Graphic Overlays Selection
Enable and disable generation of specific overlay graphics.
| Bit | 0 = do not show, 1 = show as overlay |
| 0..1 | Reserved = 0 |
| 2 | Overlay for SLATrackingBoxPixelStats_t |
| 3 | Histogram - Capture histogram green, Display histogram blue. Display histogram not supported on 17XX, 4000. |
| 4 | Track index |
| 5 | Track motion trails. NOTE: not available on 3000 with a single camera configured |
| 6 | Auto focus metric and ROI for SLASetLensParameters_t |
| 7 | Registration ignore edges for SLARegistrationParameters_t |
| 8 | MTI track index |
| 9 | Logo – Enabling this bit will insert an overlay on the video of a file that has been loaded by the user as 'userLogo.png'. To load, place the file in the user\AppData\Roaming\SightLineApplications directory, and use the firmware upgrade application to put the file on the SLA hardware. If it is not 640X150 it will not be downscaled by 2. |
| 10 | Overlay for SLALandingAid_t (turn landing aid overlays on/off) |
| 11 | Landing keep out |
| 12 | Overlay for SLADrawObject_t (turn user overlay objects on/off) |
| 13 | Draw track reticle dashed when coasting |
| 14..15 | Reserved |
Message ID 0x06
| Byte Offset | Name | Description |
| 4 | primaryReticle | Color and shape of primary track overlay.
|
| 5 | secondaryReticle | Color and shape of secondary track overlays.
|
| 6-7 | graphics | Graphic overlays selection |
| 8 | mtiColor | Color for detected tracks.
|
| 9 | mtiSelectableColor | Color for tracks which may be transitioned to primary tracks.
| Bits 0..3 | MTI selectable track color mode, BlackWhite is not supported |
| Bits 4..7 | Reserved |
|
| 10 | cameraIndex | Camera Index
255 = all cameras. If not present, applies to all cameras. |
| 11 | selectedReticle | Color and shape of selected track overlay. If not present secondaryReticle will be used for selected tracks.
|
| 12 | personReticle | Shape of track overlay when in person tracking mode. If not present default person reticle will be used
| Bits 0..3 | Person mode primary track color mode, default is cyan |
| Bits 4..7 | Reserved - reticle used will match type set in Primary, Secondary, Selected |

|
| 14 | lineThickness | Thickness of lines used for reticles, cursors, etc. Default = 1. Ignored by 1500/3000. |
| 15 | fontScale | Font scaling is used for all internal text rendering, for example this applies to drawing track index, focus metrics, track pixel stats, etc. This does not apply to user overlays. Scaling is calculated as fontScale/32. 32 is 100% scale, 0 is also treated as 100%. Default = 32. Ignored by 1500/3000. |
| 16 | fontID | Font ID for non-user objects, such as track ID etc. follows the same IDs as fonts used by the user for text strings. |
