Public bug reported:
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.
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.
