This worked perfectly. I used the following grep command to determine if a raster object existed:
whugemann, you ROCK!

That's brilliant! Makes for a lovely hack. I'll try with a few pdf files and see what works best; thanks for the lead!! I'll update this when I find something out.

Could you please suggest how this might work? I'm not so good with SED and i'm not sure what to search for.

Thanks a ton!

Thanks - unfortunately, i'm running off a shared host and there's no way they are going to allow me to install Xpdf. I'm sure the pros have some way of figuring this out.. === To give you some context on the application, I'm running a website where users can upload their files and we print them on ...

Hello,

I'd like to know if there's a way to determine if a PDF file is raster or vector, using ImageMagick. I've spent the better part of half an hour looking for this and could not find the solution.

To clarify, I mean how do I determine if there are any raster elements in a PDF file.

Thanks!

No, I get the following output:

DELEGATES bzlib fontconfig freetype jpeg jng png rsvg tiff x11 xml wmf zlib

So LCMS is missing then yeah?

Hello, I'm using ImageMagick on a shared version of TMDhosting. I am using a script that obtains the C,M,Y and K channel means from an RGB image. The command I am using to convert the image is shown below: convert -verbose "source.jpg" -profile "sRGB_v4_ICC_preference.icc" -profile ...

I knew I probably missed it; thanks again!

You Sir are amazing! I didn't find the mean.r/g/b references in the -format page! THANK YOU!!

You have to do that via fx escapes. see

Thanks Anthony! I did find a guide that explains how SED works in detail, but need to get around to reading that sometime. Really appreciate your help.. Hey is there any way that I can get the colorspace in the same command so it's more efficient than running "identify" twice? Thanks! identify ...

You Sir are amazing! I didn't find the mean.r/g/b references in the -format page! THANK YOU!! why not just do: convert rose: -format "%[colorspace]\n%[fx:mean.r]\n%[fx:mean.g]\n%[fx:mean.b]\n%[fx:mean]" info: sRGB 0.57142 0.35004 0.315563 0.412341 P.S. when I do identify -verbose rose: | \ sed -n 's ...

Hey is there any way that I can get the colorspace in the same command so it's more efficient than running "identify" twice? Thanks! P.S: Nice quote ;) Mine's not fitting for a forum where questions are meant to be asked. Got it changed :) The "sed" command can search for and extract the desired ...

Works! Thanks Anthony

Hi, I'm developing a website that uploads an image and reads the colorspace and Mean for each of the R,G and B channels. I've been able to read the colorspace using identify -format %[colorspace] rose.jpg But I'm stuck in trying to figure out how to read the Mean for each Channel.. The output for ...
