Charles Werner, the issue you are reporting is an upstream one. It would
be nice if somebody having it could send the bug to the developers of
the software via https://bugzilla.gnome.org/ . If you have done so,
please tell us the number of the upstream bug (or the link), so we can
add a bugwatch that will inform us about the status. Thanks in advance.

** Description changed:

  Binary package hint: dia
  
- When exporting a PNG Cairo picture, a menu should pop up with the desired image dimensions.
- This does not happen now with Dia 97-2.  What happens now is that a PNG image is generated with default dimensions that are too small by a factor of at least 4,  causing most of the image detail to be lost.
+ 1) lsb_release -rd
+ Description:	Ubuntu 14.04.1 LTS
+ Release:	14.04
  
- A work around is to using PNG(anti-aliased). In this case, a size popup appears and you can specify the image
- size. The default values given are too small by a factor of about 4 and you have to increase the number of pixels.
- The default values should be calculated based on the smallest features in the images, probably fonts. 
- A reasonable value would be 1 point of the font should translate to 1 pixel in the export image.
+ 2) apt-cache policy dia

+ File > Export > Determine File Type: Cairo PNG (*.png) > Save
+ 
+ and a Dia PNG Export Options window should pop open > choose the image
+ width and height > Export > open the exported file via Dia and it should
+ look exactly the same.
+ 
+ 4) WHat happens instead is that the the PNG Export Options window
+ doesn't pop up. As well, much of the detail of the exported file is
+ lost.
+ 
+ WORKAROUND: File > Export > Determine File Type: PNG (anti-aliased) (*.png) > 
+ multiply the default Image height and Image Width by ~4 to 1600 and 1200 or the image will be missing a lot of the detail > Save
+ 
+ First reported in Ubuntu 9.10 with dia 0.97-2.
