RE: dia 0.88-1 export problem? possibel workarorund?

["Tariq Rashid" <tariq inty net>]

ok - a worka round that seems to work: in case others have this problem too:

 1. in dia load the image... zoom out about twice... and select all
 2. move all the object to a place above and right of (0,0)
 3. save
 4. close dia. load anew dia
 5. load diagram and export to eps seems to work

 i'm not sure if some of the above is "magic" but it just worked for me

 again - i hop ethis gives soem clues as to where its going odd

thanks

tariq

 soory to repeat post - if its any help - i've been editting the following
inthe eps to get a reasonable diagram out so i can convert it to png...

 %% BoundingBox 0 0 x y   <- x,y were negative from dia-0.88-1 on freebsd
4.4-rel
 x y translate            <- x,y were very very large ... changed to smaller
vals byy trial ands error

does this shed any light?

keep up the good work - dia is gping to be reall solid!

 re: bad export (pape.scaling?... eps contains MASSIVE "translate values"

 thanks for the comments - i'll look into it more tonight...

 in answer to your question the platform is freebsd 4.4-release using
dia-0.88-1

 your workaround suggest changing the paper.scaling - how do i do this? i
think i see the .dia file as binary and doing an fgrep on it shows no
matching strings?

It would be nice if you could provide information about the platform
your Dia is running on. First I concluded from your mailer that it is
probably win32, but than ...

... none of my local Dia versions does open the attached file without
tweakink. (It enters an endless loop in app/grid.c:grid_draw()).

I've tracked it down to the paper.scaling value being "0" in your
file which leads to some division by zero misbehaviour done on the
paper.width and paper.height ...

see app/load_save.c:diagram_data_load around line 360.

Further calculations are done with bogus values for either scaling
or width and height or even both, so the results are almost
unpredictable ...

The workaround would be to manually correct the scaling value in
your file. But at least I have not yet found where it actually
got the invalid value in the first place so it will probably
break again ....
