Legacy ImageMagick Discussions Archive

I am very new to Image Magick and loving it so far, but have came across a problem.
While just running some tests to see if it can accomplish our needs I have come across a problem with composing a graphic into a pdf.

First test was Composing an image onto another Image, this worked out great
The .Gif isn't anything but text, and I wanted it to overlay or merge with another image, this worked out great.

Upon trying the same thing with a pdf: I ended up with a terrible resolution and a black background for the overlaying "caption.gif"

anyway to fix this so I can use it? A way to specify pdf resolution for print quality (350dpi.) and away to get rid of the background?

This background gave me problems also when trying my first test with using an .svg image.

Any help will be greatly appreciated!
Thanks in advance,
Joe

pdf is a vector format and does not have any real pixel resolution. Thus you need to tell the pdf when reading it what density you want such as 350 dpi. To do that you need to use -density and -units commands. Also I would suggest you use convert ... -composite rather than composite as convert is more flexible.

The black background issue may be due to the particular ghostscript device that is being used. You may have to edit that in the delegates.xml file. But I am not an expert on that. One delegate allows multipage pdfs, but not transparency. Another allows transparency, but not multipage pdfs. That is about all that I know.

Thanks for the quick response will look into this, and I am only working with single page pdf files so that is good.

By any chance would you by chance where delegates.xml would be located, I am currently using Ubuntu?
Thanks for the info,
Joe

OK upon trying to find my delegates.xml file I have ran
reported back
and checked out the http://www.imagemagick.org/download/delegates/

but nothing stating .pdf which delegate is for .pdf files?

ghostscript which should show up as gs in the Delegates list. I am not sure what gvc is? But the ghostscript device may need to be edited in your delegates.xml file. But work on one problem at a time. Try adding -density 350 before your input pdf and see if that helps.


My delegates are:


DELEGATES bzlib fftw fontconfig freetype gs jpeg jng jp2 lcms lqr openexr png tiff x11 xml zlib

Let me start over, maybe I am going about this wrong. (I am very new to ImageMagic)

Maybe it would be easier if I explained the project at hand to be sure that I am using the best resources available.

We were using Adobe InDesign with the Datamerge feature, we needed this because it was a way for us to produce multiple cards and marketing materials with there own card. But can not use it anymore because we need this process to be automated and InDesign can't help us with that.

Each card has the same look the only changes on each one are the group number and the url to there website.
so you know what these cards look like please go to:
http://www.rxcut.com/bishop/en/Landing1.html (thats with a text co-branded logo)
http://www.rxcut.com/FirstHarbor (that one has a tri-branded card)

Webcards are 96dpi and print cards are 350dpi. All of the marketing materials are one full page pdf each.

Question is what would be the best format for ImageMagic to produce the graphic cards? I have found jpegs to work really well, not so much luck with .svg or .png.

And also, what would be the best way to produce our marketing materials?

These are similar to the cards in the aspect that they are merged with there own card on each one and get there logo within the header. Have thought about a jpeg then converting to a pdf, but this would probably end with the .pdf size being too large.

Have tried out those links you sent but no luck! Images are still looking very pixelated. Also just tried a simple convert card.jpg card.pdf
shows nothing but a black page leaving my caption.gif that was composed onto the card.jpg the only thing visible.

I think I have something messed up! Thinking of re-installing from source rather then apt-get install imagemagic --fix-missing.

Should I install the delegates before or after or does it matter?

Install delegates before IM

well thanks although I have installed the delegates.. ImageMagick wont install correctly from source:

I have done

./configure
make
make install

tested and here is the output:

user@host:~/Desktop/ImageMagick-6.6.7-7$ display
display: error while loading shared libraries: libMagickCore.so.4: cannot open shared object file: No such file or directory
user@host:~/Desktop/ImageMagick-6.6.7-7$ identify -list configure
identify: error while loading shared libraries: libMagickCore.so.4: cannot open shared object file: No such file or directory

now it wont let me install from apt-get install imagemagick either...

Sorry, but I am not an expert on Linux. You will need some one more knowledgeable than I for installation issues.

but see http://www.imagemagick.org/script/advan ... lation.php

perhaps that may help

Thanks I fixed the install had to go to the package manager and re-install the core

but now after I had installed the delegates it appears I have less then before? And still with no ghostscript


DELEGATES fontconfig freetype jpeg jng png x11 zlib

Will keep at it, something has to work.

Ok this is starting to be a bit frustrating...
as you can see

CONFIGURE ./configure '--with-gslib'

but still no gs in the delegates... maybe I should hit up the Ubuntu forums since this doesn't seem to be an issue with ImageMagick

be sure that your delegates are installed in /usr/local/bin and /usr/local/lib. perhaps your previous ones were installed elsewhere. so you may need to reinstall any delegates including ghostscript that you want to have. Then reinstall IM.

Good call. Wont be able to test till Monday.

thanks I will try but it maybe because I am using 64-bit, have read somewhere from google that I may have to move those files to /lib64

but If these don't work I think I may switch to CentOS and give the .rpm install a shot.

Thank you so much for your help.

This seems to be an amazing app and soon I will get to experience it!
