Inkscape fails to make .pdf files the same size as the inkscape original

[Robert Carter]

It's simple, I want my .pdf file image to be 4788x1510, so I make sure I scale the whole image to that size (I've tried transform and also the manual way). Then when I save it, it turns from 4788x1510 to 3820x1208, then on top of that it crops off half of the photo. I've tried every thing: export is drawing, export is page, and both at the same time. I'm using mac version of Inkscape.

Known workaround:
1) add a new layer on top of the current one
2) move the masked image to the new layer
3) save a copy as PDF (page area)

IIRC this is already tracked in earlier reports already (masked objects are "displaced" in cairo-based exports (PDF/PS/EPS) if the parent layer or group has a 'transform' attribute).

(The page size of the PDF is identical to the size of the page in Inkscape (you can verify that by changing the units for the custom page size in the document properties of the SVG file in Inkscape):
Width: 4788.00 px --> 135.13 cm
Height: 1510.00 px --> 42.62 cm

PDF size according to Apple's Preview.app:
Page size: 135.13 × 42.62 cm

Finder info for locally exported PDF is actually '3830 × 1208'.

AFAICT the resolution shown in the Finder's 'Info' window is using pt, not px (unfortunately, it does not mention the unit explicitly). Inkscape's SVG file has the same size in 'pt', which can be verified by changing the units for the custom page size in 'Document Properties' from 'px' to 'pt'.
