in thread How to export all images from pdf via perl?

In reverse order:

"And also which option is suitable for to export all images from pdf file."

I have told you previously that if you don't use the -O option all images will be saved, this is also covered in the documentation which I have asked you to read a couple of times now.

Had you read the documentation, you may have noticed the -v (verbose) option, which will print diagnostic messages. Perhaps you could start by reading the documentation (the implication being that you understand what you are reading) and running the example again with the verbose option enabled. Are you sure that path /tmp is correct? I gave this as an example, but I notice in the first post on this topic that you are running a version of Windows.

A big part of programming is debugging, why not look at the code for extractallimages.pl, examine what it is doing, if you have any messages generated by using the verbose option find out what is causing the problem. For example, can you replicate the call to ImageMagicks convert binary outwith this script?

    Dear Monks,

    Thanks for your Guidence.

    Now i can export all the images from pdf using CAM::PDF.
    But the color is slightly varying from the original PDF image.
    Is there any possibility to export the original color of the image.
    Where can i modify the coding.

    Thanks in advance
    Prabudass

    Note:
    I am using extractallimages.pl

      Given that I have already explained that this script uses ImageMagicks convert command line utility to export images, perhaps you could start by looking at the part of the code which specifies which command line options are passed to convert, and experiment from there.

    I read the documentation. I used -v but it throws the following error message.
    "extractallimages.pl -v main1.pdf \tmp"
    Image 1, (no name) = object 49, (w,h)=(524,632)
    Failed to write file /tmp/crunchjpg.5716
    Already i created "tmp" folder. I will try in various way. Please advice me.

      list the reasons it could fail to write to /tmp/crunchjpg.5716

        I could not find the reason. Through perl IDE i compiled the "extractallimages.pl", but after the line("$tmpl->cleanoutput($ofile);") the compiler goes to "perl5db.pl" line no: 624("$SubInfo .= '('.join(', ', @test).')';"). And then process stopped. Could you please help me.
