I am waiting for your comments :)
I like the progress so far. It would be good to work on improving the
output so it works better with more PDF viewers, I think.
That shows some of the issues I'm seeing.
At the top, there is a blue box under the "NetSurf" logo and the search
box. This is just one box in the HTML, but in the output it shows that it
is segmented into several rectangles. This is because of "knockout
rendering", which was created to optimise screen redraw. It shouldn't
really be used for printing or PDF export, so I think making them bypass
the knockout rendering would improve the output.
Maybe you could edit the content redraw handlers to take a parameter
saying you're printing (or exporting in a vector format like PDF). Then
you can avoid knockout_plot_start() and knockout_plot_end() if printing in
html_redraw(). You can also avoid the text decoration "anti-aliasing"
that's done in html_redraw_text_decoration(), which is intended only for
screen redraw. (That's why underlines don't have the same blue colour as
the link text.)
Also, on the screenshots, the underline on the text "RISC OS" goes to the
end of the paragraph, but it should only underline "RISC OS".
The screenshot bitmap is not centered properly in its box, it's too far to
I'm not really sure what causes the stripes on the navigation bar, but it
looks like there could be an off-by-one error in the pdf plotter somewhere
as the thin 1px borders around the navigation links don't always show up.
The download box obviously has miss-positioned corners and missing logo
and arrow images. All of these images are created as background images in
CSS positioned boxes, so they use the tiled redraw plotter.
That image shows a PDF exported on RISC OS. As you can see the paragraph
is split over far too many lines. I'm not sure what causes this.
Could the pdf/ directory be moved and renamed to desktop/save_pdf/ ? That
would match the rest of the source better. Also is the stuff in testres/
required for anything? It would be good to either delete it or move it
which is where
the test resources are kept.
Anyway, I think the progress has been excellent so far. :)
