It's true that some PDFs have no resolution, when they're generate with text and scalable graphics. However, when a PDF is a scanned image, for example, it's basically just holding an embedded JPG image inside it, and that image has a resolution. So for example, if I scan a business card at 600dpi ...

I see in other discussions this resolution loss problem when converting from PDF to JPG. It suggests using the -density setting to counteract that. Seems odd that there is no way to get it to keep the resolution as is. If you know of a way, I would love to hear it. Also, I noticed your mogrify ...

In mogrifying PDFs to JPGs I noticed a huge reduction in resolution, which is a big problem. I suspect it kept the size, but lowered the resolution from the scan resolution to 72dpi or something. Does mogrify default to something like that? How do I get it to keep the resolution when converting the ...

thank you, I'll give it a shot.

I've put up files at http://glnk.org/watermark/ The file igra-logo-trans-500px.png is the watermark file. It's 500x500px and it has a transparent background. I'm not sure, but I'd probably want to reduce the opacity of the final watermark to not more than 50%, maybe even 30%. I could do this in ...

Could someone help me with a bash script that would go through all sub-directories and first convert all PDFs to JPGs, then watermark all JPGs with the same image? To make it easy the watermark image can just be one size and the gravity can be set to center so it will just put the image in the ...

Is there a way to get mogrify to act recursively and change all the images in the sub folders?

ImageMagick 6.6.0-4 running on Debian on a Dreamhost server.

In theory I could compile a newer version on the server, but I'd prefer to use the version already there if I can.

I have a directory that has dozens of sub-directories. Each subdirectory has multiple images. Some directories have jpegs and some have PDFs. I want to convert all the images so they are all jpegs, and they all have a common watermark. I can duplicate the main directory first, so I don't need to ...
