This test passes if the pages generated are identical for both vertical-lr and
|
||||
horizontal-tb writing-modes by means of making the size of the content we are
|
||||
printing equal to exactly the same number of pages being generated in each
|
||||
writing mode.
|
||||
This sizing is calculated like so:
|
||||
|
||||
1. It is important to note that irrespective of the writing-mode, the print
|
||||
UI always lays out printed pages vertically. Therefore, it is possible
|
||||
to equate the printed content of two different writing modes if both
|
||||
cases generate the exact same number of pages (and of course no text on
|
||||
the pages, which is why we use background color since it is independent
|
||||
of writing mode).
|
||||
2. To avoid an unnecessary vertical scrollbar (since scrolled content will be
|
||||
clipped anyway in the reftest snapshot), the maximum number of 5X3in pages
|
||||
that we should generate for the reftest snapshot are equal to 3.
|
||||
3. Considering a margin of 0.5in on each side of the 5X3in page, we get the
|
||||
size of the page content area to be 4X2in per page and to generate exactly 3
|
||||
printed pages from this in horizontal-tb writing mode, we need a printable
|
||||
area of 4X6in (as used below).
|
||||
|
||||
Similarly, the size for the test case printable area is calculated, only
|
||||
considering a vertical-rl writing mode.
|
||||
|
||||
It is important to note here that when printing this test outside of the test
|
||||
harness, the background color will not show since we omit printing and
|
||||
previewing of background colors by default via the browser printing path.
