Hi

Thanks for your very quick response and a "work-around" solution(?).
It is the first time I see someone promptly spring into action for a quick help.
I thought this was impossible here, too. I needed about 4 - 5 day only to get
the pointer form wikimedia to ask here after public question. :-/

Of cource the prominantly displayed and wrongly rendered image is still there
 (800×457 not equivalent 7x4 ). Hopefully most can understand english text.

*LOL* You are pulling my leg. :) Integers are perfect and 7.00567... or
whatever is no integer, like 7:4 is a different ratio than 800 : 457.  :)

Okay -- by convenince and "arbitrary" sizes (with a large history usage) ...
well ....

No, no .... see my proposal on

Depends on what you call render ....

Well, This I didn't know, but I knew(guessed) if doing two passes this would
be a work-around!

Well ... if this is the case, I did not know, maybe -- but I'm not an admin.
Noone told me how the original SVG size is converted to a wanted png-size.

Well ... how many sizes do you want? And in which size-range?

I guess: 4 different sizes  from 200 upto 2000 ? (as now)
A quick look to http://en.wikipedia.org/wiki/Highly_composite_numbers shows:

120     2^3.3.5         16
180     2^2.3^2.5       18
240     2^4.3.5         20
360     2^3.3^2.5       24
720     2^4.3^2.5       30
840     2^3.3.5.7       32
1,260   2^2.3^2.5.7 36
1,680   2^4.3.5.7       40
2,520   2^3.3^2.5.7 48

Well, let me suggest: 180, 360, 720, 1680  (because smaller sizes probable will 
be used more frequently). But I'm open to a different choice (or larger set).
Alle these sizes are divisible by 3 and many even by 9, but all only by 5 no by 
25! But we may bargin. ;)

Yes, but an "arbitrary" size, chosen from convinience as the just discussed? ;-)


2 points  are still open:  "Allahu Akbar"  is the correct wording not
'Alkmar Allah' as you copy from my mistakenly stated/chosen words. If you or
Valhallasw who (in the version-diff look apparently) do the change) tell me how
I could change this part of a file-description page in general, I will do it. 

2nd point in a different email.

Thanks
