I received an off-list reply from Bert that says that Scribus uses 1/72"
points internally. Again, this confirms the figures that I get for the
width & height of the objects.
However the positions are as I described them and the margins are 6mm
all around (a little less than 1/4"). If taken from the edge of the
paper, the 9mm left position which shows as 125.5... should be more like
25 points and the YPOS, which seems to be increasing as objects move
down the page, should be even smaller.
I know I've got the correct objects from their content and from the
OwnPage attribute. I also checked another object on another page (page
0) and got similar results, except the XPOS and YPOS weren't totally
wacky. I expect to see about 2.83 mm per internal unit. For OwnPage 2
objects, the XPOS was 13.9 while the YPOS were 191.9 and 113.9. On
OwnPage 0, the XPOS was 4.2 and the YPOS was 2.93.
Can anyone provide any insight into how the XPOS and YPOS numbers are set?
