\dogetobject and pdf

[Peter Münster]

[-- Attachment #1: Type: TEXT/PLAIN, Size: 555 bytes --]

Hello Hans,
I'm sorry, your patch of the May 17 works well for dvi, but not for pdf:
the figure is again shifted down and to the left.

Here an example:
\setupoutput[pdftex]
\starttext
X\externalfigure[example][width=5cm]X
\stoptext

example.pdf is attached, also the resulting pdf.


Concerning the issus with \useencoding[ffr] and FitBH:
Do you think, you could solve the problems? If not, I'll go on trying to
find solutions.

Greeting, Peter

i ran into that last week as well -)

can you try:

\def\dogetobject#1#2#3#4#5#6#7%
  {\initializepaper
   \forgetall
   \dontshowcomposition
   \setbox\scratchbox\vbox
     {\doinsertobject{#1}{#2}}%
   \setbox\scratchbox#3%
     {\vbox to #5\scaledpoint
        {\ifdim\ht\scratchbox>#5\scaledpoint
           \vss\hbox to #4\scaledpoint{\hss\box\scratchbox\hss}\vss
         \else\ifdim\wd\scratchbox>#4\scaledpoint
           \vss\hbox to #4\scaledpoint{\hss\box\scratchbox\hss}\vss
         \else
           \vss\box\scratchbox
         \fi\fi}}%
   \box\scratchbox
   \elabelgroup}

if this does not work i 'll do an upload

pdf ok now, but the dvi is shifted up and to the right... :(

Now I use a workaround in form of an environment:

\startenvironment pdf-figures
\input ifpdf.sty
\ifpdf
\def\dogetobject#1#2#3#4#5#6#7%
  {\initializepaper
   \forgetall
   \dontshowcomposition
   \setbox\scratchbox\vbox
     {\doinsertobject{#1}{#2}}%
   \setbox\scratchbox#3%
     {\vbox to #5\scaledpoint
        {\ifdim\ht\scratchbox>#5\scaledpoint
           \vss\hbox to #4\scaledpoint{\hss\box\scratchbox\hss}\vss
         \else\ifdim\wd\scratchbox>#4\scaledpoint
           \vss\hbox to #4\scaledpoint{\hss\box\scratchbox\hss}\vss
         \else
           \vss\box\scratchbox
         \fi\fi}}%
   \box\scratchbox
   \elabelgroup}
\fi
\stopenvironment

Greetings, Peter

Can you try this? You need to remake the format

Yes, dvi and pdf ok, after deleting the \dogetobject definition in
cont-new.tex.

Thank you!

Oh, excuse me. It was the old one, that fails. The new one is ok. But
without any \dogetobject in cont-new.tex it is ok too.
