[cl-pdf-devel] PATCH: pdf metainformation & min-value for histograms

[Eric Marsden]

Hi,

The attached patch makes it possible to add PDF metainformation to
generated documents: author name, keywords, generation date etc. This
information is available using the pdfinfo tool from xpdf, or under
Files -> Document Properties from Acrobat Reader. 

PDF metainformation is added by using options to WITH-DOCUMENT, as per

     (pdf:with-document (:author "Éric Marsden"
                         :title "Foo Bar")
       ...)

      
Secondly, the patch makes it possible to override the min-value and
max-value of a histogram by supplying arguments to :Y-AXIS-OPTIONS in
the constructor. The current code means that the values calculated by
the histogram code take precedence over any values supplied by the
user.
