KLV Field	Upper left X	Upper left Y	Scaling, Font	Field, Format

H Scaling

Horizontal scale shifted left 5 (e.g. 32 means no scaling. 0 is also interpreted as no scaling). Not used for font ID 5 and higher.

V Scaling

Vertical scale shifted left 5. Not used for font ID 5 and higher.

Spacing

Pixels between a font to the next font. If 0, then uses the font's default spacing. Not used for font ID 5 and higher.

Text Extended Object Type

Parameter	Bits	Description
c	0-7	Horizontal scaling is value of (Bits 0-7)/32, 0 = no scaling
c	8-15	Vertical scaling is value of (Bits 8-15)/32, 0 = no scaling
d	0-4	Font ID 0 = Courier, 1 = Courier bold, 5 = Arial, 6 = Arial Bold, 7 = Verdana, 8 = Verdana Bold, 9 = Calibri, 10 = Calibri Bold
d	5	Enable fixed width – applicable to fonts with ID 5 and higher
d	6	Enable outline effect – applicable when background color set to transparent
d	7	Enable shadow effect – applicable when background color set to transparent
d	8-15	Pixels between a font to the next font; 0 = font default spacing

Message ID 0x3B

Byte Offset	Name	Description
4	objId	Unique object ID ID Description - Maximum number of unique objects is 128 0 Used for destroying all objects when Action==Destroy 1 - 199 Unique ID for each object created 200 - 255 Reserved
5	action	Action to perform 0 = Destroy specified object ID 1 = Create new object with specified object ID
6	propertyFlags	Bits Description 0 - 3 1 Coordinates are specified in source coordinate space and object is drawn at the specified location in the source image 2 Coordinates are specified in display coordinate space and object is moved along with scene motion – equivalent to scene mode tracking with a custom overlay 4 Static overlays that do not move (such as text), coordinates are specified in display coordinate space (default) other Reserved 4 - 5 Reserved 6 0 – don't save this object, 1 – save this object (only valid if action is set to create). New 2.24 7 0 – coordinate origin (0,0) is at the center of the image, 1 – coordinate origin is at the upper left corner of the image

10-11	b	Object Type Specific Parameters
12-13	c	Object Type Specific Parameters
14-15	d	Object Type Specific Parameters
16	backgroundColor	Object Color Bits Description 0-3 Background color: for vertical and horizontal lines, the background color is drawn as a shadow; use transparent (14) to disable drawing of shadow 4-7 Foreground color: for filled objects "Automatic" will result in object being filled with a partially transparent middle gray value which can be used as a background for drawing text to ensure the text is always visible. For non filled objects it will be either white or black depending on the scene content.
17	text	Text and KLV objects only: text string (64 characters max) For KLV objects use "%s" for time, mission ID, latitude, and longitudes and "%f" for all others. Example "Time: %s" Example "Slant Range: %05.0f (ft)" Example "HFOV: %2.1f (deg)" Example "Sensor Position: %s"
