/*
-Major tasks:
- * Switch to convert the images in the background, this requires work on
- the converter, the systemcontroller and the graphics cache.
-
-Minor tasks:
- * Pop up a dialog if the widget version is higher than what we accept.
- * Provide sed/awk/C code to downgrade from InsetGraphics to FigInset(?)
-

+TODO
-/*
-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.
-
- * 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.
-
- * The scale option is only handled for the horizontal part, the vertical
- part will not work. For now it is also shown only for horizontal
- resizing on the form.
-
- * EPS figures are not fully detected, they may have a lot of possible
- suffixes so we need to read the file and detect if it's EPS or not.
- [Implemented, need testing]
-
-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.
-
-TODO Extended features:
-
- * Advanced Latex tab folder.
- * Add support for more features so that it will be better than insetfig.
- * Keep aspect ratio radio button
- * 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.
- * Add resizing by percentage of image size (50%, 150%) - usefull for two
- images of different size to be resized where they both should have
- the same scale compared to each other.

/* 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:
* 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
- * JPG/PNG direct
- * PDF direct
- * others PNG
+ * Image format
+ * from to
+ * EPS epstopdf
+ * PS ps2pdf
+ * JPG/PNG direct
+ * PDF direct
