You're on Ubuntu, right? <pre lang="bash">sudo aptitude install imagemagic</pre> That should install mogrify and bunch of other useful image manipulation tools. It’s part of the Image Magic package.

sudo aptitude install imagemagic

Set the resolution to something smaller (like 320x320 for example) and see if that drops down the size. I'd try -sample instead of -resize option - this way it will resample the image hopefully resulting in much greater size reduction. Did you do the mogrify step from above?

I don't think you can use the %03d notation this way. Have you tried running the command individually on each ps file? Alsternatively, you can try this: <pre lang="bash">for f in $(ls *.ps); do gs -sDEVICE=jpeg -dJPEGQ=100 -dNOPAUSE -dBATCH -dSAFER -r300 -sOutputFile=$f.jpg $f done</pre> This will loop through all the .ps files in the current directory and create a jpeg for each of them.

for f in $(ls *.ps); do
gs -sDEVICE=jpeg -dJPEGQ=100 -dNOPAUSE -dBATCH -dSAFER -r300 -sOutputFile=$f.jpg $f

This will loop through all the .ps files in the current directory and create a jpeg for each of them.

I used “gs -r300 -sDEVICE=pswrite -sOutputFile=ds%03d.ps -dNOPAUSE test.ps -c quit” to convert ps file which contains many images in that and
it created all individual figures
Now I am trying to convert back these ps files to jpg format
But I am unable to do it
I am using presently

“gs -sDEVICE=jpeg -dJPEGQ=100 -dNOPAUSE -dBATCH -dSAFER -r300 -sOutputFile=jds%03d.jpg ds%03d.ps”

It is not converting to jpg format
Could you please suggest me how to do it
Thanking you sir

Then you can split the original ps file with: <pre lang="bash">gs -r300 -sDEVICE=djet500 -sOutputFile=myfile.%03d.ps -dNOPAUSE myfile.ps -c quit</pre> This will produce bunch of files named myfile001.ps, myfile002.ps, myfile003.ps and etc - one file per page. Take these files and run them through the stuff above and you should be good. :) Let me know if that helps. If this doesn't work (some ps files just don't cooperate with this method_ I'd just recommend to open the ps file, and take a screenshot of each chart with something like Ksnapshot which lets you capture just a selected region of the screen.

Could you please suggest me how to solve this problem " gs -sDEVICE=jpeg -dJPEGQ=100 -dNOPAUSE -dBATCH -dSAFER -r300 -sOutputFile=myfile.jpg myfile.eps" Thanking you D Srinivas Hi,
