Annotations:Implement more annotation support: labels, notes, and dimensions| Project Report

The project was divided into two parts:

  • Fixing bugs in the annotation primitive.
  • Extending the current annotation to have more features.

Fixing bugs in the annotation primitive

    • Annotation leader line bug: the annotation leader line was invisible because of uninitialized variable.
    • Short annotations bug: using numbers for label results in no label "short annotation is not drawn":

the cause of this bug is that all the annotation points are in display space and we should consider just the point that exists in the model space.
    • new bounding box function:

the existed bounding box function was dealing in a wrong way with the long annotations because it's vlist is constructed from more than one memory chunk so the display mode was not memorized by the old function.
