virtual L_INT LAnnContainer::SaveTag(uFormat=ANNFMT_TIFFTAG, bSelected=FALSE)
Copies the annotation objects into a memory location so that the next TIFF saved will contain these annotations in a Wang compatible TIFF tag.
Format for saving annotation data. Possible values are:
Value | Meaning |
---|---|
ANNFMT_TIFFTAG | [0x0002] Save the object in WANG format, along with all LEAD properties not supported by the Wang specification. |
ANNFMT_WANGTAG | [0x0003] Save only the properties supported by the Wang specification. |
Flag that indicates which objects to save. Possible values are:
Value | Meaning |
---|---|
TRUE | Save all objects that have the selected property set to TRUE. For getting and setting the selected property, use the LAnnotation::IsSelected and LAnnotation::SetSelected functions. |
FALSE | Save only the specified object. |
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
After calling this function, saving an image as a TIFF format will cause the annotations to be saved in a tag in the TIFF file.
The annotations will not be saved unless you also save an image in one of the TIFF formats:
This tag can be cleared using LFileSettings::SetTag.
Win32, x64.
