Hi List,
when exporting plantuml code blocks to .png files, the resulting
pictures can be tiny or really huge, depending on the class hierarchy
modeled.
Is it possible to restrict the size of the graphic to the html
page-size, no matter how big the resulting .png file actually is?

cheers,
Thorsten

Have you looked at the section in the manual on exporting to HTML,
specifically the section entitled "Images in HTML export"? You can
specify whatever HTML attributes you want for the image.
By the way, I am not sure what you mean by "html page-size" as HTML has
no concept of pages, per se. Maybe you mean the width?
HTH,
eric

OK, thanks for the hint.

Yes, 'width' is what I meant by 'page-size'.

For example
#+ATTR_HTML: width="600"

Actually my question was meant with regards to Org-babel code blocks,
e.g.
,--------------------------------------------
| +name: class-diagram
| +begin_src plantuml :file class-diagram.png
`--------------------------------------------
Is it possible to specify the html 'width=600' or 'width=auto' in the
'begin_src' line or in the subtree-properties - or do I have to let my
program write the
,------------------------
| +ATTR_HTML: width="600"
`------------------------
on top of the inserted link to 'class-diagram.png' when exporting to
html?

What is plantuml? Something like gnuplot? Can't you create a png with
exactly the resolution you want?

Nice tip, thanks, it did not come to my mind that the problem might be
much easier to solve on the plantuml (textbased software for UML diagram
creation) side than on the Org-mode side, but it is - there is a 'scale'
command for zoom-functionality in plantuml:
,-----------------
| scale 1.5
| scale 2/3
| scale 200 width
| scale 200 height
| scale 200*100
`-----------------
are examples.
Although it seems impossible to determine the right relative scale
factor without knowing the grafic size a priori, this way I can offer a
pic scaled down to absolute width=600 and a download link to the
original size png.

You can put that line immediately above the #+RESULTS line after the
first time you evaluate the source code block. Subsequent evaluations
of the source code will replace the results but will leave those lines
present. See the attached example.
This is easier, in my opinion, than having to change the code to
generate a specific size, especially if have different export targets
for the same document.
HTH,
eric
