I think this is all expected behavior, although the documentation may be incorrect.
LABELPNT draws a marker on the geographic position the label is attached to. This corresponds to the center of the label text only if the label is in position CC. To draw a label at the center of the label text, another geomtransform would have to be implemented, named e.g. LABELBBOXCENTROID. regards, thomas On Sun, Dec 11, 2011 at 19:34, Brent Fraser <[email protected]> wrote: > Hey Jeff, > > I've been looking into this too (not finished yet).
