bug in \externalfigure

bug in \externalfigure

[Jannik Voges]

Hello everyone,


I found a bug in the current ConTeXt Beta with externalfigure. The following minimal example will show you what happens


\starttext

\externalfigure[cow]

\externalfigure[cow][width=10cm]

\page

\externalfigure[test]

\page

This text will appear.

This text will not appear.

\externalfigure[test][width=10cm]

This text will not appear.

\stoptext


The first two \externalfigure-commands (with cow) will give a grey placeholder with 'state:unknown' in it. The third \externalfigure-command (\externalfigure[test]) will work, and the last one won't. In this example, you will get an empty third page and the text after the \externalfigure-command doesn't appear in the pdf. 'test' can be a pdf-file or jpeg-file (I only tested whose types of files).


Thanks

Jannik

This reads in the file

  texmf-modules/doc/fonts/urw/garamond/test.tex

which is not desired. But I assume you have a “test” graphic in your
current directory which is used instead, so this is unrelated to
your problem.

When I change \externalfigure[test] to \externalfigure[cow] it works
here. The text appears.

Hi Macro,


your are right, I put a file called test.pdf (test.jpg) in my working directory.

I put an attachment with the minimal example and the pdf to this Mail. perhaps that might be better. 


Thanks

Jannik

See 
http://wiki.contextgarden.net/Using_Graphics#Specifying_image_directories

You need to add

\setupexternalfigures
     [location={local,global,default}]

I don't have the latest beta yet, so cannot comment on this.

Yes, you need "\setupexternalfigures[location=default]" for finding the
sample files of the distribution.

If you want, that other people can reproduce your problem, you have at
least 2 possibilities:
1.) You use "\setupexternalfigures[location=default]" and the sample
    files of the distribution.
2.) Or if 1.) doesn't work, you provide somewhere the needed files for
    reproducing the problem.

I think that the advice of omitting the file extension given in most LaTeX 
introductions is more trouble than it is worth in ConTeXt. Omitting file 
extensions is important if you are generating both dvi and pdf outputs. In 
ConTeXt, one never uses the DVI output, so I think that one should ALWAYS 
specify the file extension. That removes a lot of headaches with the wrong 
file being sourced.

I agree with you on that one. However, I think it's unexpected that
files from the texmf-modules/doc directory are included by default.
Hasn't it been made more strict some time ago? Why does this still
work (or better: fail):

  %% \setupexternalfigures[location=default]
  \starttext
    \externalfigure[test]
  \stoptext

One might have png, jpeg, pdf, eps and other figure files. The choice
of which will be used depends eventually on where the file is to be
found... (and setupexternalfigures). This is a *feature*. It has
nothing to do with LaTeX.

Of course, one can always specify an extension explicitly if one so
wishes...

Furthermore, the file extension is simply a convenient label which
makes no difference whatsoever on any serious system. (but not so on
more primitive operating systems. ;)

actually it's not that primitive as it helps to identify what we're 
dealing with (e.g. in the source and backend use different code paths 
for identifying the dimensions, conversion and inclusion)

Re: bug in \externalfigure

[Jannik Voges]

You are right. I was a little bit confused, because I didn't know, that you have to add 'location=default' to get the sample files, so I thought, that might also be buggy. 'test' is a test-file (pdf, jpeg, ...) in the current directory (I have not mentioned that). In my second Mail I included the source files with 'test.pdf'. You can see the bug there or when you compile the example below. This time, the sample files are loaded correctly and you will see, that the second graphic and sentence are missing.

\setupexternalfigures[location=default]

\starttext

\externalfigure[cow.pdf]

\page

This text will appear.

\externalfigure[cow.pdf][width=10cm]

This text will not appear.

\stoptext

Okay, a reader dependent bug/error. I used Preview (OS X 10.8.4). The second figure (\externalfigure[cow.pdf][width=10cm]) and the following sentence didn't appear. The same happens when you use height instead of width.

Perhaps you could add this issue to the tracker: http://tracker.luatex.org/

Hi,


yes its a tricky bug. When you view the pdf with Preview under Mac OS X (10.8.4) you will see, that the second graphic and sentence isn't displayed. When you use evince (linux) the pdf is displayed correctly. I attache a zip-file with the pdf-file of the minimal example and a screenshot of the second page, when you view it with Apple's Preview (Preview.png) and evince (Evince.png). Peter Münster reported, that he can confirm the problem with acrobat reader (I have not installed Acrobat), so I think, there is a problem with the generated pdf.

You can see the bug there or when you compile the example below. This time, the sample files are loaded correctly and you will see, that the second graphic and sentence are missing.

can you try with \nopdfcompression (that way we can look into the file)

ok, i see the problem ... will try to fix it (cannot upload from where i 
am now)

you can try this in back-pdf.lua:

function nodepool.pdfsetmatrix(rx,sx,sy,ry,tx,ty)
     local t = copy_node(pdfsetmatrix)
     if type(rx) == "string" then
         setfield(t,"data",rx)
     else
         setfield(t,"data",formatters["%s %s %s %s"](rx or 1,sx or 0,sy 
or 0,ry or 1)) -- todo: tx ty
     end
     return t
end

I added the function in back-pdf.lua, but that doesn't fix the problem.

and remake the format
