Of course, I only created a simple demo PDF file for myself, because you didn't provide one to play with....

Maybe we should ask the ImageMagick developers if they could start to create a new '-metric pr0n' measurement method. It would return a number in the range of {0..100} telling the probability in percent of an image being NSFW. McAffee could then make use of it and let pass all images which are below...

Yes, that's how it is supposed to be....

Anybody else who cannot see the image?!?

I have a .pdf file to resize, for example 95%, and convert it in .jpg. That is working fine. But if I take my .jpg to transform it back in .pdf, the image is automaticaly resized to take all the width of the document. Just in case you are going this route to resize a PDF (via ImageMagick) as an "ac...

There is no such thing as "layers" in EPS. This concept is just not present in PostScript. (It is there in PDF, though. The correct technical term in PDFs is "optional content group" {OCG}, it's only its popular name of an OCG that calls it "layer".) (If you have an EPS with "layers", I'd be interes...

[...] the size of most vector files is controlled by the density. Perhaps ps files are different. This wording is not the best to express your intended meaning. Maybe better and technically more correct say: "Vertical and horizontal dimensions of raster images created by converting from vector file...

As far as I know, there is not yet support in ImageMagick for the 'OpenRaster' (*.ora) format, nor a delegate to read or write it:

If you do not want dithering, but black filled areas and white filled areas all over the page, you need to use a different workflow. That is also possible. Please as a new question for this, and clearly state your goals. The following command line from my first post does, what I want. Black and whi...

gs -o testpage.tif -sDEVICE=tiffg4 -r300 testpage.ps tiff2pdf -p A4 -F testpage.tif > testpage.tif.pdf Thank you for the great idea to solve my problem with ghostscript. It works fine, but unfortunately the gs uses dithering. Any idea to convert in back/white without dithering? Look more closely at...

I have a problem in which IM or GhostScript can't convert PDF file with alpha channel transparency to PNG format. The PDF file was made with Adobe Illustrator's drop shadow. The conversion result PNG file does not have transparent background, but has white box background. It seems that IM or GS are...

It is, through Cygwin.

Ah. Good to know! -- Thanks for the hint.

The all.pdf file seems okay What's also interesting for future readers of this thread: how much faster was this method, compared to your original one, do it as convert * out.pdf ?? in a pdf viewer, all the pages take up the same-size space on the screen, This is because your PDF viewer very likely ...

... pdfimages ... Ah, very useful, excellent, thanks. This answers the problem of extracting images from PDF files. That program writes one PAM file per image, no fuss, no worries about density. IM can read the PAM files in the usual way. The Windows version does not have all the options I used in ...

I install my delegates from MacPorts, but install IM from source manually. see http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=21502&p=88202&hilit=OSX+MacPorts#p88202 IIRC, I tried to also compile a released source tarball (as opposed to current SVN checkout), and this also failed. ...
