Dear list,

Most graphics-able exporters support some form of a scale parameter,
sizing the resultant image as a function of the original graphics file
(intended) size.

This is true for:
  * built-in ODT exporter
  * ox-pandoc Latex/ODT/DOCX exporters.

This possibility comes handy to avoid (or at least master) the side
effects of scaling (fonts amplification, /reduction, bitmap fuzinness,
etc...).

It should be supported on the native LaTeX exporter (and possibly
"scale: 1" may become the default...).

In addition (but this is probably a different problem), some
scaling/sizing mechanism may be implemented for the HTML exporter.

Attached is my proposal for the feature I suggested. My quick tests
pass[1]. Better tests by someone knowledgeable in graphics would be 
useful, as well as a test in the test suite.

HTH,

[1] I get unrelated failures from "make test" :
4 unexpected results:
   FAILED  test-org-clock/clocktable/extend-today-until
   FAILED  test-org-clock/clocktable/step
   FAILED  test-org/timestamp-from-string
   FAILED  test-org/timestamp-from-time

I can't see any link with my proposal. BTW, I get the same failures
from the unmodified master branch (fetched this morning...).

Applied, with some slight fixes.

Could you provide an entry in ORG-NEWS?

Possible duplicate answer (my email provider isn't very reliable at the
moment...).

A patch it is (enclosed).

If this documentation is customaty, this should be mentioned in the
"Contribute" page of Worg (which, IMHO, should be pointed to by the 
"Feedback" section of the manual).

Feel free to edit Worg, it is user-maintained. OTOH, I don' think the
manual should rely on the wiki. We could, instead, augment
"README_contribute".

We are now on June 16. The ELPA-distributed org-plus-contrib still does
not carry these patches (re-attached, FWIW).

I have checked that they are present in the ~master~ branch of the
source tree, but not its ~maint~ branch.

Am I misunderstanding anything ?

+*** New ~LATEX_ATTR~ ~:scale~ supported by the built-in LaTeX exporters
+
+The builtin ~org-latex-export*~ exporters now accept and use a
+~:scale~ attribute, which scales an image by a given factor.
+
+This attribute is wrapped adound the ~scale=~ parameter of LaTeX's
+~\\includegraphics~ (bitmap images) or a ~TiKZ~'s
+~\\scalebox~. Therefore, its value should be some string palatable to
+LaTeX as a positive float Its default value is an empty string
+(i.e. disabled).
+
+This attribute *overrides* the ~:width~ and ~:height~ attributes ;
+therefore, while it can be given a default value, this should be done
+only under exceptional circumstances.

New features are applied to master branch. maint branch is for bugfixes
only. 

Since your patch is a new feature, it went into master branch. It will
be available in Org 9.3. Hopefully, it should not be long, even though
I have no ETA. I'm Cc'ing Bastien as he may know.
