Re: [O] Failure to display more than 18 images with captions

This looks like a user configurable option, e.g.

(setq org-latex-default-figure-position "htbp")

Fair enough. I changed the default value for the variable.

Thank you for the explanation.

Re: [O] Failure to display more than 18 images with captions

I think Jean Louis is right: it _is_ an org issue.   The problem is that
the default value of org-latex-default-figure-position is "htb", which is a
very bad idea.  The string always needs to contain a "p" in it somewhere,
otherwise latex will never be able to find a solution for figure placement
in cases with many floats and little or no text.

Fuller explanation: The position specifiers "h" (here), "t" (top), and "b"
(bottom) are all for placing floats on a page that has some "normal" text
on.  For all 3 cases, there is a minimum fraction of the page that must be
occupied by text (controlled by the parameter \textfraction, which by
default is 0.2).  To get pages that are entirely occupied by floats, you
need to use the specifier "p" (page).  So, by just using "htb" you are
giving latex a set of requirements that are impossible to satisfy if there
are many floats and no text.  Hence the problem with "Too many unprocessed
floats".  I would recommend that the default be "htbp" instead.

Re: [O] Failure to display more than 18 images with captions

[Jean Louis]

IMHO, the program Org Mode shall not give error when exporting PDF, or
it should be documented that certain number of pictures are not
tolerated and how to increase that number or how to avoid the problem.

Maybe something like explained here:
http://tex.stackexchange.com/questions/46512/too-many-unprocessed-floats

like "morefloats" package:
ctan.org/pkg/morefloats

or \extrafloats{100}

But I did not get that working, I have simply turned off floats.

It looks to me like no part. It is a Latex issue.

Re: [O] Failure to display more than 18 images with captions

[Jean Louis]

Thank you. It is possible to increase the number of floats in LaTeX, but
I could not succeed.

I found out that problem is also in compilation of the table of
contents, so when I turned toc off, I could see pictures.

Further, I am now using non-floats with:

#+ATTR_LATEX: :float nil

and I can get now the file to work fully as I am expecting, including
pictures are on the place where I wanted them to be.

It is solved for me, not solved in general as a problem in Org mode.

Re: [O] Failure to display more than 18 images with captions

[John Kitchin]

this looks like an issue related to floats. It works with out the
caption because they are not floats in that case. But, with floats,
there are limits.

see
http://tex.stackexchange.com/questions/46512/too-many-unprocessed-floats.

According to that page:

LaTeX can, by default, only cope with 18 outstanding floats; any more,
and you get the error “too many unsuppressed floats”. This package
releases the limit; TeX itself imposes limits (which are interdependent
of the help offered by e-TeX). However, if your floats can’t be placed
anywhere, extending the number of floats merely delays the arrival of
the inevitable error message.

You may be able to add \clearpage every few figures or use a package
that makes this work.

Majority of LaTeX errors are like following:

[O] Failure to display more than 18 images with captions

[Jean Louis]

Hello,

I have problem with Org Mode, that it fails to display more than 18
images correctly, while exporting to PDF (LaTeX export).

I am using images in following manner:

#+CAPTION: Title of image
#+NAME: fig:pic001
[[/some/image001.jpg]]

#+CAPTION: Title of image
#+NAME: fig:pic002
[[/some/image002.jpg]]

#+CAPTION: Title of image
#+NAME: fig:pic003
[[/some/image003.jpg]]

 and so on until 40-50 images ...

#+CAPTION: Title of image
#+NAME: fig:pic060
[[/some/image060.jpg]]

If I only put links without CAPTION and NAME, the export is working
well, but images are not nicely formatted. If I am using CAPTION without
NAME, I get the same problem, so only 18 images are displayed.

I have tried to display random images, to verify is it about the link or
what would be the cause, but always 18 images are displayed.

Few images are displayed on the side of the PDF, cut, not visible,
covering the right side border of the PDF file.

I would really need help to get it working, as I use Org Mode for
reporting.

Thank you,
J. Louis
