Public Attributes |
| AIReal | segmentOffset |
| | An AIReal in which the integer part is an anchor point index into the AIPathSegment list of a path, and the fractional part is a t-value along the bezier between that anchor point and the next one (usually 0).

| AIReal | fractionalOffset |
| | An AIReal in which only the fractional part is significant, and represents the t-value along the entire flattened path length.

Detailed Description
Identifies a specific point along a path, in two different ways.
Used to keep track of the point selections on a partially selected path, if they will be needed after the path is modified. These values (along with the number of points the path had before modification) can be used to match a point value to its corresponding point after the modification. Depending on the type of modification, one of the representations changes, but the other remains invariant.
- If the number of points after an edit is the same as when the match was specified, use
segmentOffset. Use for transformations or distortions of the whole path, as well as edits that move some or all of the points.
- If the number of points after an edit is different from when the match was specified, use
flattenedOffset. Use for edits that add or delete points without changing the geometry of the path.
Member Data Documentation
An AIReal in which only the fractional part is significant, and represents the t-value along the entire flattened path length.
This can change if anchor or control points are moved.
An AIReal in which the integer part is an anchor point index into the AIPathSegment list of a path, and the fractional part is a t-value along the bezier between that anchor point and the next one (usually 0).
This is the same as the offset. See AITextPathSuite::GetTextPathOffset().
This can change after points are inserted or deleted in the path.
