    ### 5) IMAGES: RESIZING WITH IMAGE MAGICK CLI:

    #### Resize and compress by 85% and autonumeral (%02d -> two digits)
    `magick *.jpg -resize 1440 -quality 85 ./resized/AH_000003-%02d.jpg`


    #### Rotate 90 degrees if height > width
    `convert input.jpg -rotate 90< output.jpg`

    #### Save the output file with the same filename as original (after rotating the image on this example)
    `-set filename:f` --> key we want to set
    `'%t'` --> value we assign to the previous key. %t is a shortcut to retrieve the filename. The long form is `%[basename]`

    `magick planos/*.jpg -rotate '-90<' -set filename:f '%t' planos/'%[filename:f].png'`

    #### Save the output file containing the directory name on its filename. The input file must contain the direcoty on its path, so you must be one level up...

    ```
    $~/Desktop >
    magick AH_000007/*.jpg -resize 1440 -quality 85 -set filename:myname '%d' AH_000007/resized/'%[filename:myname]-%02d.jpg'
    ```

    The output file names will be something like:
    `AH_000007-01.jpg`
    `AH_000007-02.jpg`
    `AH_000007-....jpg`


    #### Resize and output to a different folder with same file names
    `mogrify -resize 1440 -quality 85 -path ./resized *.jpg`


    #### Output filename autonumber starting from a specific value.
    Using the -scene [number] flag, where [number] is the number where the automatic count starts from.
    On the following example, will output files autonumber starting from 5 (05,06,07...)
    `magick AH_000032/*.jpg -resize 1440 -quality 85 -scene 5 -set filename:myname '%d' AH_000032/resized/'%[filename:myname]-%02d.jpg'`


    ### Convert images to pdf
    `convert *.png -quality 100 document.pdf`
