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]
-
- * If we are trying to create a file in a read-only directory and there
- are graphics that need converting, the converting will fail because
- it is done in-place, into the same directory as the original image.
- This needs to be fixed in the src/converter.C file
- [ This is presumed to be fixed, needs testing.]
-
- * We do not dither or resize the image in a WYSIWYM way, we load it at
- its original size and color, resizing is done in the final output,
- but not in the LyX window.

TODO Before initial production release:
- * Replace insetfig everywhere
- * Search for comments of the form
- // INSET_GRAPHICS: remove this when InsetFig is thrown.
- And act upon them. Make sure not to remove InsetFig code for the
- 1.2.0 release, only afterwards, after deployment shows InsetGraphics
- to be ok.
- * What advanced features the users want to do?
- Implement them in a non latex dependent way, but a logical way.
- LyX should translate it to latex or any other fitting format.
