2 * \file InsetGraphics.cpp
3 * This file is part of LyX, the document processor.
4 * Licence details can be found in the file COPYING.
9 * Full author contact details are available in file CREDITS.
15 * What advanced features the users want to do?
16 Implement them in a non latex dependent way, but a logical way.
17 LyX should translate it to latex or any other fitting format.
18 * When loading, if the image is not found in the expected place, try
19 to find it in the clipart, or in the same directory with the image.
20 * The image choosing dialog could show thumbnails of the image formats
21 it knows of, thus selection based on the image instead of based on
23 * Add support for the 'picins' package.
24 * Add support for the 'picinpar' package.
29 * The filename is kept in the lyx file in a relative way, so as to allow
30 * moving the document file and its images with no problem.
34 * Postscript output means EPS figures.
36 * PDF output is best done with PDF figures if it's a direct conversion
37 * or PNG figures otherwise.
