shell - Problems using ImageMagick for converting PDF with accented characters -

-

i having problem when converting pdf images using imagemagick or ghostscript. accented characters disappear converted image. found couple of people having same problem , apparently updating imagemagick package , ghostscript fixed it, not me.

i using pdf file on every tests made: https://www.dropbox.com/s/3gso0sw1e1n8f9r/error-with-accents.pdf?dl=0

i have ubuntu 14.04.2 lts server on azure need imagemagick work. official repositories have imagemagick 6.7.7 , ghostscript 9.10. later, tried upgrading them in order fix issue , have imagemagick 6.8.9-10 running on /opt/imagemagick-6.8 folder , added ubuntu's 15.04 repository install ghostscript 9.15 directly through apt-get. none of these fixed problem me.

here latests attempts on ubuntu 14.04 server:

all same results:

im-test-6.7.7.jpg

i able run ghostscript , imagemagick correctly on mac os. and, according this post, versions have on ubuntu should work. i'm thinking it's related freetype fonts. know nothing on how fix this. help?

the pdf document trying process very often modified , re-saved: 455 times between 2010-03-06 , 2014-06-17.

you can verify running pdfinfo -meta error-with-accents.pdf.

i not speak or read portuguese, cannot recognize if accent missing in output image 1 should be.

when tried command, im v6.9.0-0 q16 x86_64 2015-05-14 (using ghostscript v9.16), no see error:

enter image description here

your pdf has fonts uses embedded (see emb column). means, freetype not employed replacement/substitute font:

$ pdffonts error-with-accents.pdf     name                       type       encoding         emb sub uni object id   -------------------------- ---------- ---------------- --- --- --- ---------   ruxyww+conduititc-light    type 1c    macroman         yes yes no      14  0   noyzmg+y2kneophyte         truetype   winansi          yes yes yes     10  0   mvlykx+conduititc-medium   type 1c    macroman         yes yes no      15  0   jdnvdm+conduititc-bold     type 1c    macroman         yes yes no      13  0

in case: should concentrate version of ghostscript processes pdf correctly. because imagemagick not pdf processing on own -- relies on ghostscript "delegate" so.

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
