0001239: Fit to Font Size option for Relationship Graph

Notes
(0002907) bmcage (administrator) 2007-09-20 00:25	I think this is out of our control. We pass commands to the Graphviz program, that makes the page. One of the things we can pass is font size. So the user must determine by trial and error what the good fontsize is, combined with number of pages and paper size. As graphviz has no options to automatically set fontsize to paper size relation, there is nothing else we can do.

(0002910) drbeams (developer) 2007-09-20 11:49	Someone is looking at this. The solution has been proposed, but has not been tried yet.

(0002913) bmcage (administrator) 2007-09-20 14:30	Reminder sent to: pez4brian drbeams/Ahmuck says you will look at this. Hope your idea works, remember changing dot page numbers to get fontsize/pagenumber ration ok for printing

(0003475) pez4brian (administrator) 2007-10-12 20:10	I did some tests. If we don't specify a paper size, Graphviz will render the graph in the optimal size. We could easily add an option to ignore paper specification. There is one snag, however - PDF. PDF generation requires that we specify a paper size. It is quite easy for a user to do this themselves. They can just generate a .dot file, remove the paper specifications from the file, and then use Graphviz to generate the graph. So, while this is possible, I'm not sure how to handle PDF. Suggestions are welcome. One question is this: do we need this? Don't users usually want to specify the size of the graph? If they are worried about the size being too small - causing fonts to be grainy - they can just choose a really large paper size.

Secondly: For printing: No, I, as a user, would not use that feature at the moment. I have instead used the feature "use optimal number of pages", and I always select the paper size. When creating flash-files, I would use this if I could generate them from pdfs such as to include links to the narrative web-site, bacause then I would like to use a minimal paper size, and only one page, but I think I failed using pdf2swf (http://www.swftools.org/ [^]) for some reason.

(0004975) bmcage (administrator) 2008-02-11 01:25	Johan, for swf, did you pass over ps file or not? As in http://www.gramps-project.org/wiki/index.php?title=Make_flash_plugin_from_a_png [^]

(0004985) johan (reporter) 2008-02-11 04:04	On using pdf2swf: I do not remember what I used at that time. When trying now, I succeed, except for the ps2pdf step, which only captures part of the ps document. The forum for discussing that is not here, though. On the question: Is this feature useful: I said I might this feature for generating flash files. For practical use, generating an svg file instead of has been proposed, and was discarded by me as being to inefficient to use in viewers. In a firefox 3 beta on ubuntu gutsy, performance for viewing svg files is very usable for me (some 800 individuals in the graph), and thus I will aim at not using flash anymore. Therefore, my reason for wanting this feature is probably not valid anymore.
