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 it
- when choosing a file it doesn't update the select file input line.
-
-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.
-
- * How do we handle the inline viewing? we may need to show the same image
- in several formats (color, monochrome, grayscale) or even in different
- sizes, not to mention rotations!
-
-TODO Basics:
-
- * Add support for more features so that it will be better than insetfig.
- * Keep aspect ratio radio button
-
- * Create the GraphicsCache and FormatTranslator
- * Add inline viewing of image.

+ Note that browseRelFile in helper_funcs.* provides a file name

+ level or below, and an absolute path if the file name is not a
+ `natural' relative file name. In any case,
+ MakeAbsPath(filename, buf->filePath())
+ is guaranteed to provide the correct absolute path. This is what is
+ done know for include insets. Feel free to ask me -- JMarc

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.
-
- * Pop up a dialog if the widget version is higher than what we accept.
- * 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.

/* 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
- * Get into lyx-devel as an unactivated inset for the benefit of those
- * who really need it.
*
- * 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
