-Immediate tasks:
- * Make the inline viewing work, there is a preliminary work going on,
- need to finish it up.
-
- * Polishing tasks:
- * Add messages in the empty rectangle to say how are we doing.
- - Implemented, needs testing.
- * Clean up GraphicsCacheItem(_pimpl)
- * Pop up a dialog if the widget version is higher than what we accept.
- * Prepare code to read FigInset insets to upgrade upwards
- * Provide sed/awk/C code to downgrade from InsetGraphics to FigInset.

-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.
- * Bug in FileDlg class (src/filedlg.[hC]) when selecting a file and then
- pressing ok, it counts as if no real selection done. Apparently
- when choosing a file it doesn't update the select file input line.
- * Inline viewing is still not completely operational, in fact it is no
- disabled. To enable it enable the define:
- INSETGRAPHICS_INLINE_VIEW
-
-Current PROBLEMS:
-
- * How to support both PDF and PS output, should we do the conversion
- or should we just give the bounding box and tell latex how to do the
- conversion itself?
- I (Baruch Even) tend towards doing the conversion ourselves, otherwise
- we need to give latex quite a few translation commands and from the
- graphicx package docs it appears that it takes quite a bit of memory
- on the side of TeXing.
-
-TODO Basics:
-
- * Add support for more features so that it will be better than insetfig.
- * Keep aspect ratio radio button
-
- * Work on inline viewing of image.
-
-TODO Before initial production release:
- * Replace insetfig everywhere
- * Read it's file format
- * Get created by all commands used to create figinset currently.
- * Search for comments of the form
- // INSET_GRAPHICS: remove this when InsetFig is thrown.
- And act upon them.
-
- * Finish the basic To-do list.
- * Extract the general logic of the dialog in order to allow easier porting
- to Gnome/KDE, and put the general logic in frontends and the inherited
- platform dependent code in the appropriate dirs.
-
-TODO Extended features:
-
- * Advanced Latex tab folder.
- * Add even more options to make it better than insetfig.
- * Support for complete control over the latex parameters for TeXperts
- * 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.
+ * 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.
- * 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.
- * 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:
- *
- * Intentions:
- * This is currently a moving target, I'm trying stuff and learning what
- * is needed and how to accomplish it, since there is no predefined goal or
- * way to go I invent it as I go.
- *
- * My current intention is for seperation from LaTeX, the basic needs are
- * resizing and rotating, displaying on screen in various depths and printing
- * conversion of depths (independent of the display depth). For this I'll
- * provide a simple interface.
- *
- * The medium level includes clipping of the image, but in a limited way.
- *
- * For the LaTeX gurus I'll provide a complete control over the output, but
- * this is latex dependent and guru dependent so I'd rather avoid doing this
- * for the normal user. This stuff includes clipping, special image size
- * specifications (\textwidth\minus 2in) which I see no way to generalize
- * to non-latex specific way.
- *
- * Used packages:
- * 'graphicx' for the graphics inclusion.
- * 'subfigure' for the subfigures.
- *
* Fileformat:
- *
- * Current version is 1 (inset file format version), when changing it
- * it should be changed in the Write() function when writing in one place
- * and when reading one should change the version check and the error message.
- *
* 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:
- *
- * Apparently the PNG output is preferred over PDF images when doing PDF
- * documents (i.e. prefer imagemagick eps2png over eps2pdf)
- */
-
-/* Current Stage:
- * Embryonic.
*
- * PLAN:
- * Finish basic support:
- * Inline image viewing
- *
- * Do Release quality support:
- * Allow to change display depth
- * Make default figure instead of InsetFig
- * Add to LyX (probably after 1.1.6 is released)
- *
- * Extended features:
- * Output format conversion
- * Print depth changes
- * Image file tracking of changes.
+ * Conversions:
+ * Postscript output means EPS figures.
*
- * Extended^2:
- * Image roll-in (how? when? why?)
- * This means to add the image inside the LyX file, usefull when
- * transferring the file around.
+ * 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
