Question
ImageMajick convert
I have two similar servers with centos 5. One is a development server one production. both use standard packages manged with yum. I would like to continue using standard packages
the convert command is behaving behaving differently between the servers. the production server gives me a memory allocation error while converting monochrome tif to pdf.
the dev server the one that works has 1 gig of memory
the production server has 4 gig
convert test.tif test.pdf
convert: Memory allocation failed `test.pdf'.
the command works with smaller images. the images I want to convert are monochrome scans of documents. group4 compression
I did try passing some options to convert which seemed to make not difference, also it is not unnecessary on the dev system. the dev system does create a monochrome compressed pdf without passing any options
convert test.tif -monochrome -compress Group4 -quality 100 -units PixelsPerInch -density 600 test2.pdf
Am I missing some package that conversion to pdf uses?

thanks for you help RQuadling
It is very strange. the cmand you use works fin on the Developmetn server but not on the production server.
Production:
$ convert test.tif -monochrome -compress Group4 -quality 100 -units PixelsPerInch -density 600 test.pdf
convert: Memory allocation failed `test.pdf'.
Also tiff2pdf does work on productions server. however at first glance it does not seem to allow you to create a multi page pdf from multiple single page tiff files. This in one thing I am doing with convert on the dev server. I will look into this option more.
As for upgrading ImageMagick. I was hoping to make this all work on a vanilla centos5 server. centos5 packages include ImageMagick 6.2.8. The advantage to not upgrading is we can continue to manage the os with standard packages. also, what is really bugging me is that it works on the other sever with the same version.
RQuadling,
I'm not convinced it is an issue with the version. it is working using same version on a different machine.
The single page tiff images are tagged with imagesMagick because I am converting them from huge multi page tiff files into single page tiff files. I'm doing this because the multi page tiffs are unruly to work with. The files that come to me are sometimes over 20 meg over 500pages containing mixed documents. I convert them to single pages then figure out which pages go with each document. some are single page documents. some are multiple pages. then I hope to create separate pdfs for each document which are often 2-5 pages long.
I would look into tiffsplit and tiff2pdf. Significantly faster the convert and way less memory. Even on windows.
OOI. Are you sure both packages are the same? I'm not a unix person, but having seen the way that options are specified to configure/make/install things, it seems likely a small difference is enough to make things work/not work.
If the 2 machines are physically identical, does it stand to reason that you could use the binary from the working machine?
If so, so if that works. It may be that the build process detected some difference and pushed that into the build process.
Thank you very much for all your help with this Problem. Although I never figured out the specific problem of convert running on one server but not the other, you provided better alternatives. Since I'm not doing any kind of compresion, size, resolution, etc conversion here I don't need convert.
I am now using tiffsplit to separate big multi-page. tiffcp to join them back into smaller docs. then tiff2pdf to create a downloadable doc for the user. This is much faster than convert.
I'll post some code here when I am done with it.

Are there any other differences between the production and dev servers?
can you post the test.tif file?
