Message ID 0x4D

Byte Offset	Name	Description
4	absOffZoom	Bit 1: Zoom mode; 0 = (1..255) maps to (0.9..1.1), 1 = (1..255) maps to (0.004..0.996) Bits 0 and 2-7 reserved
5	up	Number of pixels warp image is shifted up
6	right	Number of pixels warp image is shifted right
7	down	Number of pixels warp image is shifted down
8	left	Number of pixels warp image is shifted left
9	rotation	Rotation of warp image (1..255) maps to (-5..5) degrees
10	zoom	Scale factor applied to warp image (1..255) maps to (0.9..1.1) or to (0.004..0.996) depending on value of absOffZoom
11	mode	Blend mode (see SLASetBlendParameters_t)
12	amt	Amount of luminance information from the EO (visible) camera to include in the blended result. Applies to: Frame Blend, Night Blend, Color Blend, Thermal Blend and Color IR Blend modes.
13	hue	Amount of yellow hue to apply from bright areas in the EO camera. Applies to: FrameBlend and NightBlend modes
14	flags	See SLASetBlendParameters_t
15	reserved	Reserved
16	warpIndex	Image from camera with this index into the space of the other camera through the calibration settings before blending
17	fixedIndex	Image from camera with this index is not warped before blending with warp image
18	usePresetAlign	Image alignment parameter index. 0 Use the alignment parameters in this message. 1 Use a preset alignment (defined by SLASetMultipleAlignment_t or SLAFourAlignPoints_t) and set index of preset alignment parameters to value of presetAlignIndex
19	presetAlignIndex	Indicate index of preset alignment parameters – ignored if usePresetAlign is 0. Indexes 0..4 are used for alignment sets defined by SLASetMultipleAlignment_t. Indexes 10..14 are used for alignment sets defined by SLAFourAlignPoints_t.
20	hzoom	Horizontal zoom scale applied to EO camera (1..255, 0=no change) on top of zoom. maps to (0.9..1.1) Verical zoom = zoom Horizontal zoom = hzoom * zoom
21	hotStart	Applies to: ThermalBlend, beginning value for hot palette.
22	coldEnd	Applies to: ThermalBlend, ending value for cold palette.
