<h2>wx.lib.pdfviewer</h2>
|
|
|
|
The wx.lib.pdfviewer.pdfViewer class is derived from wx.ScrolledWindow
|
|
and can display and print PDF files. The whole file can be scrolled from
|
|
end to end at whatever magnification (zoom-level) is specified.
|
|
|
|
<p> The viewer uses <b>pyPdf</b> to parse the pdf file so it is a requirement that
|
|
this must be installed. The pyPdf home page is http://pybrary.net/pyPdf/
|
|
and the library can also be downloaded from http://pypi.python.org/pypi/pyPdf/1.12
|
|
|
|
<p> There is an optional pdfButtonPanel class, derived from wx.lib.agw.buttonpanel,
|
|
that can be placed, for example, at the top of the scrolled viewer window,
|
|
and which contains navigation and zoom controls.
|
|
|
|
<p>Alternatively you can drive the viewer from controls in your own application.
|
|
Externally callable methods are: LoadFile, Save, Print, SetZoom, and GoPage.
|
|
(See pdfviewer.__init__.py)
|
|
|
|
<p> The viewer renders the pdf file content using Cairo if installed,
|
|
otherwise wx.GraphicsContext is used. Printing is achieved by writing
|
|
directly to a wx.PrintDC and using wx.Printer.
|
|
|
|
<p> Please note that pdfviewer is a far from complete implementation of the pdf
|
|
specification and will probably fail to display any random file you supply.
|
|
However it does seem to be OK with the sort of files produced by ReportLab that
|
|
use Western languages. The biggest limitation is probably that it doesn't (yet?)
|
|
support embedded fonts and will substitute one of the standard fonts instead.
