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.
