Cambria: integral sign has wrong size

Cambria: integral sign has wrong size

[Julian Becker]

[-- Attachment #1.1: Type: text/plain, Size: 499 bytes --]

Hello everybody!
I tried doing some math typesetting with Cambria, but somehow the integral
sign comes out somewhat smaller than it should be.
Running the following   in the latest beta produces the  attached pdf. Does
anybody have an idea about what's going wrong here, or how to fix it?

It is a regression (it was ok with older context versions) but I am not
sure what is causing it. The most likely cause is that the metrics
patch to CambriaMath is no longer applied, but I do not quite remember
how to check that.

Best wishes,
Taco

This is a known bug in the Cambria font, the size of the big operators 
is not set correctly, but AFAIK ConTeXt already accounts for this by 
applying a custom font patch.

In this case, is there a quick workaround? I tried something like redefining
\int
using
\def\int{\getglyph{CambriaMath}{\char"F05C2}\intlimits}

This gives the desired result in displaystyle, but is incompatible with
scriptstyle math. Is there a way to adapt this workaround to account for
this in some way?

Best regards,
Julian

Try setting \Umathoperatorsize\displaystyle=2em or so until you find a
suitable value.

It will be fixed in the next beta, in the meantime you can replace 
cambria-math.lfg by this:

local function FixDisplayOperatorMinHeight(value,target,original)
     local o = original.mathparameters.DisplayOperatorMinHeight
     if o < 2800 then
         return 2800 * target.parameters.factor
     else
         return value -- already scaled
     end
end

return {
     name = "cambria-math",
     version = "1.00",
     comment = "Goodies that complement cambria.",
     author = "Hans Hagen",
     copyright = "ConTeXt development team",
     mathematics = {
         parameters = {
             DisplayOperatorMinHeight = FixDisplayOperatorMinHeight,
         }
     }
}
