The DICOMTEXTOBJECT describes the attributes of a "Text Annotation" object.

Members

uStructSize

The size of the structure (use sizeof (DICOMTEXTOBJECT)).

DICANN_UNIT_DISPLAY [0x00000002] "DISPLAY"

bAnchorPointVisible

"Anchor Point Visibility" (0070,0015) attribute value. Possible values are:

Value Meaning
TRUE "Y"
FALSE "N"

pReserved

Reserved for internal use -- Pass 0.

uCompoundGraphicInstanceId

TAG_COMPOUND_GRAPHIC_INSTANCE_ID

uOptions

pTextStyle

TAG_TEXT_STYLE_SEQUENCE

uGraphicGroupId

TAG_GRAPHIC_GROUP_ID

Comments

The members of this structure are based on some of the attributes of the "Graphic Annotation Module", please see "Graphic Annotation Module Attributes" in the DICOM standard for more details.

Special note about the following members: pszLayerName, pszTextValue, pTLHCorner, pBRHCorner and pAnchorPoint:

When you call a function, which updates this structure (ex. L_DicomGetTextObjectInfo), LEADTOOLS will fill these members with pointers to the internal memory, which LEADTOOLS manages. You must not free these pointers. When you call a function, which updates internal data from the structure you provide (ex. L_DicomSetTextObjectInfo), LEADTOOLS expects you to fill these members with pointers to memory that you have allocated and that you manage. You must free these pointers when they are no longer needed.
