Creates a PDF from multiple images. One page per image.

If you want a specific arbitrary order you can use {1,3,5,10,12}

* you may use jpg, tif etc

** if you do use jpg images you might want to add "-compress Zip" as suggested below to prevent from having the images from being re-compressed.

To ignore aspect ratio, run:

for file in *; do convert $file -resize 800x600! resized-$file; done

and all images will be exactly 800x600.

Use your shell of choice.. This was done in BASH.

for file in `ls *.png`;do convert $file -resize 65% new_$file; done

mogrify can be used like convert. The difference is that mogrify overwrites files:

http://www.imagemagick.org/www/mogrify.html

Of course, other source colors can be used as well.

soffice --headless -convert-to odt:"writer8" somefile.docx

In this example, the docx gets converted to Open Document .odt format.

For other formats, you'll need to specify the correct filter (Hint: see "Comments" link below for a nice list).

Outputs the number of different pixels.

2 params to increase tolerance:

* thumbnails size

* fuzz, the color distance tolerance

A simple command to extract audio from flv/mp4 video file.

Just change extentions...

this assumes that all comics are saved as xkcd-[number]-[title].{png|jpg}.

it will then download the title and alt-text, create pictures from them, and put everything together in a new png-file.

it's not perfect, but it worked for nearly all my comics.

it uses the xkcd-json-interface.

though it's poorly written, it doesn't completely break on http://xkcd.com/859/

Creates a better looking gif than the original post via imagemagick processing high quality jpgs, rather than converting directly to gif from the video itself.

You can use "decode()" in a similar manner:
