Hello, two questions about pages in PDF document (slightly refers to the code http://www.mail-archive.com/ntg-context@ntg.nl/msg57502.html):
----
local MyDocument = lpdf.epdf.load("A4.pdf")
context.starttext()
local pages = MyDocument.pages
local dummy = MyDocument.pages[1] -- we need lua 5.2 in order to avoid this
local nofpages = #MyDocument.pages
context.starttabulate { "|c|c|c|" }
context.NC() context("page")
context.NC() context("width")
context.NC() context("height") context.NR()
for i=1, nofpages do
local page = pages[i]
local bbox = page.CropBox or page.MediaBox
context.NC() context(i)
context.NC() context(bbox[4]-bbox[2])
context.NC() context(bbox[3]-bbox[1]) context.NR()
end
context.stoptabulate()
context.stoptext()
----
The sample gives: w ~ 842 pt, h ~ 595 pt
Questions:
1. Shouldn't be width and height swapped? As the analyzed 'A4.pdf' has width of 210
mm and height of 297 mm, IOW width < height, whilst the cld code gives w > h
(?!).
2. Is it possible to get rotation or orientation of the page (be "portrait" or "landscape" or
"0" or "90" or so)?
3. Is the 'bbox' already affected by the page rotation/orientation? I mean - in
the case page orientation is 90 or 270, is the width and height of 'bbox'
swapped compared to the situation if page orientation was 0 (or 180)?
Best regards,
Lukas
