\getfiguredimensions again in mkiv

\getfiguredimensions again in mkiv

[Aditya Mahajan]

Hans,

Something is also wrong with getting the width and height of a figure in 
mkiv. Minimal example:

\starttext
\getfiguredimensions[filename]
\figurewidth
\figureheight
\stoptext

To be precise, I get 0sp 0sp as output, rather than the correct dimensions 
of the figure.

The results in MkII and MkIV are inconsistent. Minimal example:

\setupexternalfigures[location={local,default}]
\starttext
\getfiguredimensions[cow]

\startlines
width: \figurewidth
height:\figureheight
\stoplines
\stoptext

In MkII I get,

width: 276.03125pt
height: 200.75pt

In MkIV I get,

width: 7592528sp
height: 5694396sp

which translates to (why doesn't MkIV use pt as units?)

width:115.85pt
height:86.889pt

I don't know if this is a bug in grph-inc.lua or in luatex.

i'll look into it

concerning pt ... tex internally uses sp so this is what mkiv uses
in tex-lua communications

you can use:

\startlines
width:  \the\dimexpr\figurewidth\relax
height: \the\dimexpr\figureheight\relax
\stoplines

This is still wrong. Using the following example,

It appears that the dimension for width is being used for height. I could 
not find an obvious mistake in grph-inc.

I mean that the dimension for height is being used for width.

For unscaled images you can use \figurenaturalwidth and 
\figurenaturalheight.

I was using 2010.02.09. The current version, 2010.02.23 works fine. Sorry 
about the noise.
