The DICOMGRAPHICLAYER structure is used by the functions LDicomDS::CreateLayer to create a layer, and by LDicomDS::GetLayerInfo and LDicomDS::SetLayerInfo to get and set the attributes that describe a DICOM graphic layer.

Comments

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

Special note about the following members: pszLayerName, puGrayscale, pRGBLayerColors, and pszLayerDescription:

When you call a function, which updates this structure (ex. LDicomDS::GetLayerInfo), 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. LDicomDS::SetLayerInfo), 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.
