SLASetDisplayParameters_t Struct Reference

Description

Set new display parameter settings.

typedef struct {
  u16 rotationDegrees;
  u16 rotationLimit;
  u8 decayRate;
  u8 falseColorZTT;
  u8 zoom;
  s16 panCol;
  s16 tiltRow;
  u8 cameraIndex;
  u16 extendedZoom10;
  u16 zoomRate;
  u8 flipMode;
} SLASetDisplayParameters_t;

Current rotation is smoothly changed to specified value, digital zoom, and false color are directly controlled.
NOTE: For 1500, these parameters are applied to the Command Camera.

Message ID 0x16

Byte Offset	Name	Description
4-5	rotationDegrees	Rotation angle in degrees (0..360) * 128
6-7	rotationLimit	Rotation rate limit in degrees (0..360) * 128 per frame, (default 256). See Rotation angle NOTE above.
8	decayRate	Rotation decay rate per frame, 0(0%) to 255(100%) (default 50). See Rotation angle NOTE above.
9	falseColorZTT	Bits 0 - 6: False Color Modes Bit 7: Zoom mode: 0 = zoom to center of display, 1 = zoom to tracking box
10	zoom	Zoom – digital image magnification factor times 64. NOTE: Zoom may be further limited for some camera and display combinations. NOTE: If extendedZoom10 and zoomRate are set, this field is ignored Value Result 0 to 15 No zoom(1X) (subject to change) 16 to 63 Zoom out by 0.25 to 0.98 64 No zoom(1X) 65 - 255 Zoom in by 1.01 to 3.98
11-12	panCol	Display pan column offset in pixels
13-14	tiltRow	Display tilt row offset in pixels
15	cameraIndex	(Optional) Ignored for 1500. Settings applied to this camera index: Omit and current Command Camera will be used. 255 = All cameras.
16-17	extendedZoom10	Value Result 0 to 255 No zoom(1X) (subject to change) 256 to 511 Zoom out by 0.25 to 0.499 512 to 1023 Zoom out by 0.5 to 0.999 1024 No zoom(1X) 1025 to 4095 Zoom in by 1.001 to 3.999 4096 to 16383 Zoom in by 4.0 to 15.999
18-19	zoomRate	0 to 1023 Measured in frames per X16 For example, a display with a zoom rate of 45 and a framerate of 30fps will move from X1 to X16 zoom in 1.5 seconds.
20	flipMode	Mirror and Flip mode: 0 = normal 1 = mirror (flip left to right) 2 = flip (flip top to bottom) 3 = mirror and flip (flip left to right and top to bottom)
