Inset-icons are auto-scaled according to their width.
This is problematic, if converted from SVG
with the bounding box set to content (ignoring the page size)
and the content is not square.
OTOH, ignoring page size is done for good reasons - we usually want just
the drawing area when inserting an image into a document.
An invisible square with fixes this problem.
Some icons had spurious invisible elements outside the page -- leading
to too small results in the PDF. These were removed.
These icons are for lfuns that are not very interesting for users, but quite
often used when working on the LyX documentation. Now we can create a special
LyX documentation toolbar.
- Restore proportion between icons, such that, for example, \imath
is not confused with a lower case 'l' or \textdegree with \circ
- Use real \mathbb and \mathcal TeX icons
I'll revise also the other sets in the Math Panels toolbar along
these lines. It is important to see whether a symbol has ascendents
or descendents or what is their relative size.
- Use paths, not fonts. Have a look at the sqrt icon in the image attached
here http://thread.gmane.org/gmane.editors.lyx.devel/154179/focus=154183
to see what may happen when a font is not present on a given system.
- Make uniform the height of the parentheses.
- Move a couple of icons to the oxygen subdir (I was not sure it was Ok
replacing them. If yes, they can be simply deleted).
I did not notice that all icons in math/ are shared and in a0895046 I have
overwritten some of them. I am restoring them in the proper subdir.
Two of them, namely font.svgz and frac.svgz, give warnings that should
be addressed. Anyway, I see that these icons use fonts. They are better
substitued with paths (a menu entry in inkscape) because if the fonts
are missing on a system, the icons look different and, in general, they
may look ugly.
You have to manually delete the lib/images/svg directory as git
tracks only files.
There may be warnings on the terminal due to some faulty icons that have
to be found and corrected. Moreover, some of the icons are not rendered
too well at the default size. These ones should be properly tweaked.
Kudos to Jürgen for putting together such a large number of icons.
The svg files produced by vector editors may end up containing a lot
of unused elements that increase their size without any impact on
quality. For example, this occurs when copy/pasting between images
such that unused effects or shadings simply clutter the files.
Removing these elements in some cases may reduce the size to one half
or one third of the original one, leaving unmodified the image quality.
I also tweaked some existing icons to make them look better at default size.
Moreover, some text was replaced with paths, because the required font may
not exist on a system and font substitution would take place, making the
icons look different on different systems.
I am also replacing some existing icons with reworked ones that
look better at small sizes. I think that these icons are now
comparable to the png ones as regards quality at the default size.
These are SVGs from the Tango icon set as well as some theme-independent self-made icons. Many icons are missing. This set s a wild mixture of Tango, old KDE icons and some self-made icons drawing on (to me) unknown models.
I leave the task to finish this set (and thus the SVG icons generally) to others.
These are automatically generated via the generate_symbols_svg script. Some were modified manually afterwards.
These certainly need some manual care, and a number of icons are missing (cannot be created automatically). But it is a start.
This is a follow-up of bug #8967. The implementation is self-explaining, the
only part which needs a comment is lyx2lyx: Since a 100% correct solution is
not possible, it has been decided not to switch amsmath off in the forward
conversion if no other ams command than \smash[t] and \smash[b] is used, but
to consider it a bug that older versions do not load amsmath automatically for
these commands. In the backward direction it is easy to keep the document
compilable, so just do that.
The autogenerated icons are in most cases ugly, do not conform to the
style of the other icons, and do not respect relative dimensions and
positions. The math icons have a vertical dimension of 19 pixel, defining
a grid that has to be respected for obtaining correct alignment.
The only autogenerated icons that remain are those of the Misc (extra)
toolbar. I plan to also replace them in the near future.
Somehow I overlooked that \sideset also supports nonscript arguments for
left and right. This is now fixed, although I do not like the toolbar names.
If somebody knows something better, please improve.
The toolbar image is the one Uwe attached to the bug report. Note that
\sideset works only for operators like \sum in the nucleus. LyX allows
any content, so you might get a LaTeX error. I don't know how to prevent
wrong content in the nucleus.
This patch implements 'move row' and 'move column' features for tabular.
The purpose is to provide a useful behavior in tabular that is
consistent with PARAGRAPH_MOVE_UP and PARAGRAPH_MOVE_DOWN so that the
user can, for example, do alt-<up> to move a row up. Alternatively,
icons for these features are also added to the table toolbar and
context menu.
If there is any selection, the feature is disabled. This is consistent
with how PARAGRAPH_MOVE_UP works in other contexts. Additionally, 'move
row' is disabled if there is a multi-row in the current or target row;
and 'move column' is disabled if there is a multi-column in the current
or target column.
'move row' moves only the left and right borders of a cell along with
the row. Similarly, 'move column' moves only the the top and bottom
borders.
Implementing similar functionality for other insets, such as arrays and
array environments, is on my TODO list.
Most images are generated by development/tools/generate_symbols_images.py, but
some were drawn manually. Now there is no image missing from the ones the
script can generate.
The fix is basically mechanical, the additional code for fraction like insets
with three arguments was stolen from \unitfrac. As any math package,
stackrel.sty needs a buffer parameter to switch it off.
I also added the two stackrel flavours to the toolbar.
These are all generated by development/tools/generate_symbols_images.py, the
only manual adjustments were renamings due to case sensitive file systems on
windows.
stmaryrd.sty sets these symbols up as variable size math delimiters (i.e.
they may be used with \left and \right). Now LyX knows about that and offers
them in the delimiter dialog as well as single symbols.
Now that we have module support for literate programming, it is possible to do a noweb cleanup. This is basically a patch from Kayvan Sylvan:
- get rid of literate-xxx classes
- rename Scrap to Chunk, since this is the name noweb doc uses (Scrap is from nuweb)
- update lyx file format and add lyx2lyx support for gettting rid of literate-xxx classes
- update documentation
On the top of it, update tex2lyx to
- avoid creating files with literate-xxx class
- fix conflict between parsing << as a quote and parsing it as a Chunk
- create Chunk layouts instead of Scrap ones.
