Hi Regina --
I saw that you had already made some changes yesterday re i118191
https://issues.apache.org/ooo/show_bug.cgi?id=118191
I have not investigated color renderings in AOO at all in terms of
values,
but my first thought is we should be consistent across modules on
how this
is done. RGB vs HTML?
I have compared Calc to StarMath to HTML in the attachments. There is
currently no consistence between Calc and Math.
Kind regards
Regina
Thanks for your research. I started thinking maybe making these
consistent
across all modules (really I have not looked into this yet), would be a
good "easy" fix for a new volunteer. What do you think?
For module Math it is too late to make it an "easy" fix, because the fix
is finished, beside the question, what color to use. When I started I
had no idea how easy or hard it would be.
Right, I saw your changes but didn't evaluate the extent.
For Calc I have looked around, but could not find the place yet. So if
someone can provide a pointer, then it might work. But I'm not sure
because localization is involved.
Back to the question, which color to use:
Foreign (not OpenOffice or LibreOffice) .odf documents will use the
html-color-names and those names are standardized. So for that names I
think, there is no choice, we have to render them as they are defined in
the standard. Do you agree?
Of course, we have to use what is defined in the standard.
sure, I see this as a rethorical question. ;-)
So the color name "red" will be #ff0000 in Math as it is already in
Calc, and the color name "blue" will be #0000ff in Math as it is already
in Calc. That gives a more consistent use and solves issue i118191. But
old documents will be rendered different.
The color name green in Math has the same rendering as green in html, so
that can stay. For Calc it can be solved, when the color name "lime" is
allowed too and mapped to the light green and "green" to the dark green.
Color names are not stored in the Calc files and therefore old documents
are not affected.
The question is, what to do with names "cyan" and "magenta"? These names
do not belong to the standard. So we can decide, which color OpenOffice
renders and which color it writes to the file. If Math will use them the
same way as Calc, then "cyan" has to be rendered same as "aqua" and
"magenta" same as "fuchsia". OpenOffice writes currently "aqua" and
"fuchsia" to the MathML part of the file already. That would make the
names consistent between Math and Calc and between rendering via
StarMath and rendering via pure MathML. But old documents would be
rendered different. Shall I change the rendering of "cyan" and "magenta"
to the light colors too?
Personally, I would make them consistent from this day forward, so I
would say "yes" make MathML the same as Calc.
I just found this reference area for color codes/names--
http://www.rapidtables.com/web/color/cyan-color.htm
cyan = aqua in rgb
http://www.rapidtables.com/web/color/purple-color.htm
same for magenta = fuchsia
Others may have a different opinion though.
Another thing is to take the compatibility to older documents into account.
When changing the colors so that they look like the user would expect
due to the standard, then OK. But if this means also that colors in
older documents will now look different, then ... hm ... it needs to be
investigated how bad it really would be.
