paper background position
paper background position
hi,
using dd 1.13, with an mfc app similar to odamfcapp.
i'm having trouble changing the position of the paper background. when i open a drawing in paperspace, the white paper background looks perfect. when i use the setmediasize() routine to change the paper size, that seems to work fine. the problem occurs when i try to change the page setup of the drawing. in other words, if i open a drawing which starts at a plot scale of 1:1 and change it to 2:1, the paper background does not reflect this. same problem happens with any changes to the page setup (plot area, plot offset, etc.) i've tried using the setlimmin() and setlimmax() routines, but this don't seem to change anything. i check these values after and they are different, but they don't change anything visually. if i save the drawing and open it in autocad, it also doesn't display the paper background like i intended it to. but if i open the page setup dialog box and click ok, the paper background is then set correctly. something isn't getting set by my program. any ideas what i need to do? thanks.
hi,
ddt has functionality to drawing of paper background if it was set by autocad page setup dialog. functionality from ddt to autocad drawing is not implemented, i.e. you cannot change scale factor and save drawing, due to some other paper space parameters should be changed also. when you open drawing in autocad after scale changing, call page setup, autocad will recalculate all plot dependent parameters and set it to drawing.
all printing\page setup functionality are mfcapp functionality, i.e. part of sample. mfcapp is very limited sample in printing way. it works fine if you open drawing in autocad and save it with system available printer device parameters (from autocad page setup dialog).
all other cases are user responsibility .

re: paper background position
thanks alexander. is it possible to just change the ddt display of the paper background? if it doesn't change the autocad paper background correctly after saving, that's ok. i'd be fine if i could just update the paper background in my own application. earlier versions of ddt could do this using setlimmin() and setlimmax().
