savebox within tikzpicture results in an empty savebox
Using savebox
within a tikzpicture
environment seems wipe out the content of the savebox
.
In the MWE below, the following macros define, measure and display the size of a savebox
:
newcommand*{DefineBoxAndItSize}{%
saveboxtempboxA{Hg}%
%% https://tex.stackexchange.com/a/11945/4301
setlengthSizeOfBox{dimexprhttempboxA+dptempboxArelax}%
}%
newcommand*{ShowBoxAndSize}{%
Box fbox{usebox{tempboxA}} is printlength{SizeOfBox}%
}
As long as DefineBoxAndItSize
is invoked outside of a tikzpicture
, using ShowBoxAndSize
both outside (first line of output) and inside a tikzpicture
environment (second line of output) works fine.
However, the third line invokes DefineBoxAndItSize
inside a tikzpicture
before ShowBoxAndSize
, which ends up making the box empty.
Question:
How can I define a savebox
within a tikzpicture
environment?
Code:
documentclass[10pt]{article}
usepackage{tikz}
usepackage{printlen}
newsavebox{tempboxA}
newlength{SizeOfBox}
fboxsep=0pt
newcommand*{DefineBoxAndItSize}{%

the box is saved, but it saves the same text that it would typeset if you used that text at that point. (look in the log for missing character messages)

Background: TikZ happens to gobble text unless it is an argument of a node. Even though this is sort of well known, this also has less obvious implications. In particular, saveboxes may end up being empty. This has already lead to confusion here and here. In the latter post, the OP solves the issue by wrapping their macro in begin{pgfinterruptpicture}
and end{pgfinterruptpicture}
.
The next step of sophistication, which may or may not deserve a new answer, might then be to wrap the savebox definition in an begin{pgfinterruptpicture}
and end{pgfinterruptpicture}
only if the macro is called inside a tikzpicture
environment. To this end, the tests of this post and this post are employed. (Let me remark that the IfInTikzPic
is a bit unusual in that its first argument is the action that is to be taken if one is not in a tikzpicture
environment. Whether or not this is related to the author driving on the other side of the road, I don't know. ;-)

Background: TikZ happens to gobble text unless it is an argument of a node. Even though this is sort of well known, this also has less obvious implications. In particular, saveboxes may end up being empty. This has already lead to confusion here and here. In the latter post, the OP solves the issue by wrapping their macro in begin{pgfinterruptpicture}
and end{pgfinterruptpicture}
.
The next step of sophistication, which may or may not deserve a new answer, might then be to wrap the savebox definition in an begin{pgfinterruptpicture}
and end{pgfinterruptpicture}
only if the macro is called inside a tikzpicture
environment. To this end, the tests of this post and this post are employed. (Let me remark that the IfInTikzPic
is a bit unusual in that its first argument is the action that is to be taken if one is not in a tikzpicture
environment. Whether or not this is related to the author driving on the other side of the road, I don't know. ;-)

I'll be happy to remove this answer if people feel that this question is a duplicate and thus does not deserve a separate answer. (However, at the time of writing this, I am reputation capped, so the reason is certainly not to harvest reputation points, which it is in none of my posts.)
EDIT: Fixed a space, big thanks to Phelype Oleinik!

Deserves one upvote solely for the remark onIfInTikzPic
. Brilliant! (and for the answer, of course). One comment: I'd add a%
afterbegin{pgfinterruptpicture}
to align the last sentence.

Yes, it is rather well know, until you encounter an error and spend time trying to figure out what is going on, without remembering that detail! :-(

@marmot: Nah, its fine. I just end up asking too many embarrassing questions!!! As always, I continue to blame it on lack of sleep.

@PeterGrill Yes, nothing is better than a good amount of hibernation time. (And no, I don't think it is an embarrassing question. I just happen to have come across this a few months earlier.) Ah, I also edited the answer.

the box is saved, but it saves the same text that it would typeset if you used that text at that point. (look in the log for missing character messages)

@marmot: Yep. Using
begin{pgfinterruptpicture} DefineBoxAndItSize end{pgfinterruptpicture}
works. You want to post an answer? Not sure I would imemdiately have seen this as a related issue had I seen the referenced question.– Peter Grill
Nov 13 '18 at 22:09
@PeterGrill Have you also seen this question? It seems to be slightly closer to yours, and the OP added
begin{pgfinterruptpicture} ... end{pgfinterruptpicture}
to their macro (as well). I agree that your question is not a precise duplicate. I can add an answer, but I also think there would be nothing wrong if you answer your own question. Please let me know what you like better.– marmot
