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 * Add a way to roll the image file into the file format.
19 * When loading, if the image is not found in the expected place, try
20 to find it in the clipart, or in the same directory with the image.
21 * The image choosing dialog could show thumbnails of the image formats
22 it knows of, thus selection based on the image instead of based on
24 * Add support for the 'picins' package.
25 * Add support for the 'picinpar' package.
26 * Improve support for 'subfigure' - Allow to set the various options
32 * The filename is kept in the lyx file in a relative way, so as to allow
33 * moving the document file and its images with no problem.
37 * Postscript output means EPS figures.
39 * PDF output is best done with PDF figures if it's a direct conversion
40 * or PNG figures otherwise.
