IIUC you're asking that we implement the default behavior for CSS3 Paged Media margin boxes:
Margin boxes have an initial value of zero for padding, border and margin. The default height of top boxes is the value of the page box's top margin. The default height of the bottom boxes is the value of the page box's bottom margin. The initial value for 'content' is 'none'. The initial 'width' and 'height' of margin boxes is 'auto'. http://www.w3.org/TR/2006/WD-css3-page-20061010/#populating-margin-boxes In other words, we won't be rendering any content for headers or footers. You're also asking that we implement page size, and portrait vs. landscape: http://www.w3.org/TR/2006/WD-css3-page-20061010/#page-size Will that do the trick for the pdf.js use cases? -- Jet > We need to implement the CSS3 stuff anyway. How about: -- Implement CSS3 Paged Media sufficient to make headers/footers and margins go away, select page orientation and size. That shouldn't be too hard. -- Add an event to canvas that fires per-page during printing to render that canvas content while we're printing the page it's on. This event would provide a special canvas context that's compatible with the 2d interface but internally renders at higher resolution (or possibly emits PS/PDF directly). Then you could create a print document that's just a series of canvases, with the appropriate CSS to remove headers/footers/margins etc, and as we print each page we'll run the callback on each canvas to paint it more accurately. Any temporary resources could be thrown away after painting that page. _______________________________________________ dev-tech-layout mailing list [email protected] https://lists.mozilla.org/listinfo/dev-tech-layout
