- This chapter lists the major known problems in IRIS
- Annotator 1.1.2
-
- +o The Annotator file format has changed. Although
- Annotator 1.1.2 can read both the new and the old
- format, Annotator 1.0 cannot read the new 1.1.2 file
- format. To work around this, you can convert the
- Annotator 1.1.2 file using the _i_v_d_o_w_n_g_r_a_d_e utility
- program, shipped with the Open Inventor 2.1 (or 2.1.1,
- 2.1.2) Execution Environment. Note that _i_v_d_o_w_n_g_r_a_d_e
- produces an ASCII file, which is much larger than the
- original Annotator binary file.
-
- +o The Annotator User's Guide has not been updated to
- reflect the new items in the ``Notes'' menu. Nor has it
- been updated to document the change from MedaiMail to
- Netscape mail.
-
- +o Some model data may not be transferred correctly when
- you mail an annotated scene, or when you copy a model
- from one Annotator session and paste it into another
- (or into another application). The problem occurs when
- the model refers to other files through SoFile nodes,
- or SoTexture2 nodes; the receiver of the mail, or the
- application doing the paste, may not find the
- referenced files. To work around this you can expand
- the model file to include all the data inline before
- reading it into IRIS Annotator. Use 'ivcat -tfb
- oldmodel > newmodel' to expand the model.
-
- +o Sometimes you cannot pick objects constructed from
- NURBS surfaces. When that happens, try moving the
- cursor a little, or adjust the view slightly, before
- trying again.
-
- +o Sometimes when you switch to the orthographic camera in
- the viewer, you can no longer pick objects, or attach
- arrow markers to objects. When this happens, switch to
- the perspective camera again (using the bottom icon in
- the icon column on the right hand side of the Annotator
- main window).
-
- +o If you hit "Cancel" in the capture tool while recording
- a Movie note, the movie data will be deleted, but the
- note icon remains attached to the marker. However, if
- you try to play the note, it won't find the data.
- Remove the icon by clicking on it, and then selecting
- ``Delete'' in the Edit menu.

-
- +o The first time you run Annotator, when you start the
- capture tool to create a new note, capture may not
- start in the correct mode, or the capture window may
- flash briefly, then disappear. If it starts in the
- wrong mode, you can fix the problem by selecting the
- correct mode using the button pop-up menu in the lower,
- left corner of the capture window. If the capture
- window flashes, then disappears, you can fix the
- problem by running capture once from the desktop.
- (Select ``Find->Media Tools'' from the toolchest, then
- double click on the capture icon. When the capture
- window appears, select ``Quit'' from the ``Actions''
- menu).
-
- +o If the Texture Editor is open when you iconify the
- Annotator window, the selected object will no longer be
- visible in the Texture Editor when you de-iconify the
- window. To get the object back into the Texture
- Editor's viewer, close the Texture Editor, and then
- re-open it.
-
- +o When you change the material of an object (using the
- Material Palette or Editor) while the Texture Editor is
- open, the material change is not always reflected in
- the Texture Editor's viewer. When this happens,
- deselect the object in the main Annotator window, and
- then re-select it. Alternatively, you can close the
- Texture Editor, and then re-open it.
-
- +o When you undo/redo a texture mapping operation, the
- operation is undone/redone in the main Annotator
- window, but not in the Texture Editor's viewer. To see
- the change also in the Texture Editor, deselect the
- object in the main Annotator window, and then re-select
- it. Alternatively, you can close the Texture Editor,
- and then re-open it.
-
- +o The -r and -R options require an absolute pathname for
- the input file. For example, the following sequence of
- commands will cause an Annotator error message to pop
- up indicating that the file Pear.iv cannot be found:
- % annotator
- % cd /usr/share/data/models
- % annotator -r Pear.iv
-
- However, the following sequence will correctly insert
- the Pear.iv model into the Annotator scene:
- % annotator
- % annotator -r /usr/share/data/models/Pear.iv

-
- +o Playing Movie notes may alter the hardware audio
- sampling rate. Consequently, any Sound notes that
- follow may not sound right.
-
- +o Cut or Copy of existing multimedia notes, sometimes
- gets a bus error and core dump.
