-Known BUGS:
-
- * If the image is from the clipart, and the document is moved to another
- directory, the user is screwed. Need a way to handle it.
- This amounts to a problem of when to use relative or absolute file paths
- We should probably use what the user asks to use... but when he chooses
- by the file dialog we normally get an absolute path and this may not be
- what the user meant.
-
- Note that browseRelFile in helper_funcs.* provides a file name
- which is relative if it is at reference path (here puffer path)
- level or below, and an absolute path if the file name is not a
- `natural' relative file name. In any case,
- MakeAbsPath(filename, buf->filePath())
- is guaranteed to provide the correct absolute path. This is what is
- done know for include insets. Feel free to ask me -- JMarc
- 14/01/2002
-
-TODO Before initial production release:
+TODO
* What advanced features the users want to do?
Implement them in a non latex dependent way, but a logical way.
* Add a way to roll the image file into the file format.
* When loading, if the image is not found in the expected place, try
to find it in the clipart, or in the same directory with the image.
- * Keep a tab on the image file, if it changes, update the lyx view.
* The image choosing dialog could show thumbnails of the image formats
it knows of, thus selection based on the image instead of based on
filename.
