The DISPANNOTATIONPROPS structure contains options for controlling the annotation objects appearance and behavior.

Description

uStructSize

Size of this structure in bytes, for versioning. Use the sizeof() function to calculate this value.

crAnnotationColor

COLORREF value that specified the annotation color. This color will be applied as the default color for the newly created annotation if uFlags was set to DCANNOTATION_APPLYCOLOR_FORNEW.

bSimpleRuler

Flag that indicates whether to show the annotation ruler with tick marks. Possible values are:

 

Value

Meaning

 

TRUE

The ruler will not have tick marks; it will be like a simple line. This is the default value.

 

FALSE

The ruler will have tick marks and gauges.

 

uFlags

Flags the control the behavior of the annotation object. You can combine values together when appropriate by using a bitwise OR ( | ). Possible values are:

 

Flags that determine on which annotation object the new setting will be applied:

 

Value

Meaning

 

DCANNOTATION_APPLYTO_SELECTED

[0x00000000] Apply on selected object.

 

DCANNOTATION_APPLYTO_ALLOBJECT

[0x00000010] Apply on objects that have the same type. (All rulers or all arrows).

 

DCANNOTATION_APPLYTO_ALL

[0x00000020] Apply on all annotation objects.

 

Flag that sets the options in this structure as the default options for the newly created annotation objects:

 

Value

Meaning

 

DCANNOTATION_APPLYCOLOR_FORNEW

[0x00000100] The new setting will be the default setting for the annotation object that will be created.

Comments

This structure is used by LImageViewer::SetActionProperties and LImageViewer::GetActionProperties functions.

This structure is mainly used to change or retrieve the properties of the annotation objects, and it works only with the following actions:

CONTAINER_ACTION_ANNOTATION_RULER

CONTAINER_ACTION_ANNOTATION_ANGLE

CONTAINER_ACTION_ANNOTATION_TEXT

CONTAINER_ACTION_ANNOTATION_ARROW

CONTAINER_ACTION_ANNOTATION_RECTANGLE

CONTAINER_ACTION_ANNOTATION_ELLIPSE

CONTAINER_ACTION_ANNOTATION_HILITE
