/** * \file insetgraphics.C * This file is part of LyX, the document processor. * Licence details can be found in the file COPYING. * * \author Baruch Even * \author Herbert Voß * * Full author contact details are available in file CREDITS. */ /* TODO * 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. * 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. * 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. * Add support for the 'picins' package. * Add support for the 'picinpar' package. * Improve support for 'subfigure' - Allow to set the various options that are possible. */ /* NOTES: * Fileformat: * The filename is kept in the lyx file in a relative way, so as to allow * moving the document file and its images with no problem. * * * Conversions: * Postscript output means EPS figures. * * PDF output is best done with PDF figures if it's a direct conversion * or PNG figures otherwise. * Image format * from to * EPS epstopdf * PS ps2pdf * JPG/PNG direct * PDF direct * others PNG */ #include #include "insets/insetgraphics.h" #include "insets/render_graphic.h" #include "buffer.h" #include "BufferView.h" #include "converter.h" #include "cursor.h" #include "debug.h" #include "dispatchresult.h" #include "exporter.h" #include "format.h" #include "funcrequest.h" #include "FuncStatus.h" #include "gettext.h" #include "LaTeXFeatures.h" #include "lyx_main.h" #include "lyxlength.h" #include "lyxlex.h" #include "metricsinfo.h" #include "mover.h" #include "outputparams.h" #include "sgml.h" #include "frontends/Alert.h" #include "frontends/LyXView.h" #include "support/convert.h" #include "support/filetools.h" #include "support/lyxalgo.h" // lyx::count #include "support/lyxlib.h" // lyx::sum #include "support/lstrings.h" #include "support/os.h" #include "support/systemcall.h" #include #include #include namespace support = lyx::support;
