Hello,
There were several discussions last year [1, 2] about how to handle image
orientation in XHTML-Print documents. The PWG has asked the W3C's CSS
Working Group to consider CSS mechanisms to specify the orientation of an
image with respect to the document's orientation in 90 degree increments
first and at an arbitrary rotation second.
I'm asking for comments about the type of rotations needed:
1. rotation about the center of the image
2. rotation about an edge: flip horizontally or vertically
3. rotation about a diagonal
4. rotation about any (x,y) point in Cartesian space, inside or outside of
the image
5. other (please specify)
The rotation is independent of rotations implied by portrait versus
landscape printing.
For example, consider a document that contains 2 paragraphs of text printed
in portrait orientation on a letter sized piece of paper. An image placed
within the text would also have portrait orientation. The same document
printed in landscape orientation would require that the printer rotate both
the text and the image. However, the text and image would still have the
same orientation with respect to each other, regardless of portrait or
landscape printing.
This information will help the CSS working group specify css property that
will meet the needs of the user community.
You may send comments to either the W3C style mailing list
(www-style@w3.org), this mailing list (xp@pwg.org), or directly to me.
