Scaling Mode:
The default mode of operation is scaling mode with fixed paper
size and scaling pre-set to 0.95. By not using the resize mode
you are using scaling mode. Flip-Detection and Auto-Rotation are
disabled in Scaling mode.
- The default mode of operation is scaling mode with fixed paper
size and scaling pre-set to 0.95
- By not using the resize mode you are using scaling mode
- Flip-Detection and Auto-Rotation are disabled in Scaling mode,
you can use '-r source -s <scale>' to override.

Resize Paper Mode:
Disables the default scaling factor! (0.95)
Changes the PDF Paper Size in points. Will fit-to-page.
- Disables the default scaling factor! (0.95)
- Changes the PDF Paper Size in points. Will fit-to-page

Mixed Mode:
In mixed mode both the -s option and -r option must be specified.
The PDF will be first resized then scaled.
- In mixed mode both the -s option and -r option must be specified
- The PDF will be first resized then scaled

Output filename:
The output filename is optional. If no file name is passed
the output file will have the same name/destination of the
input file with added suffixes:
- Having the extension .pdf on the output file name is optional,
it will be added if not present.
- The output filename is optional. If no file name is passed
the output file will have the same name/destination of the
input file with added suffixes:
.SCALED.pdf is added to scaled files
.<PAPERSIZE>.pdf is added to resized files
.<PAPERSIZE>.SCALED.pdf is added in mixed mode

Page Size Detection Modes:
a, adaptive Default mode, tries all the methods below
g, grep Forces the use of grep method

Custom Paper Size:
Paper size can be set manually in Milimeters, Inches or Points.
Use: pdfScale.sh -r 'custom <measurement> <width> <height>'
Ex: pdfScale.sh -r 'custom mm 300 300'
Measurements can be: mm, inch, pts.
Custom paper definition MUST be quoted into a single parameter.
Actual size is applied in points (mms and inches are transformed).

in, inch, inches
Use: pdfscale -r 'custom <measurement> <width> <height>'
Ex: pdfscale -r 'custom mm 300 300'

Using Source Paper Size: (no-resizing)
- Wildcard 'source' is used used to keep paper size the same as the input
- Usefull to run Flip-Detection and Auto-Rotation without resizing
- Eg. pdfscale -r source ./input.dpf

Options and Parameters Parsing:
- From v2.1.0 (long-opts) there is no need to pass file names at the end
- Anything that is not a short-option is case-insensitive
- Short-options: case-sensitive Eg. -v for Verbose, -V for Version
- Long-options: case-insensitive Eg. --SCALE and --scale are the same
- Subparameters: case-insensitive Eg. -m PdFinFo is valid
- Grouping short-options is not supported Eg. -vv, or -vs 0.9

Additional Notes:
- Adaptive Page size detection will try different modes until
it gets a page size. You can force a mode with -m 'mode'.
- Options must be passed before the file names to be parsed.
- Having the extension .pdf on the output file name is optional,
it will be added if not present.
- File and folder names with spaces should be quoted or escaped.
- The scaling is centered and using a scale bigger than 1 may
result on cropping parts of the pdf.
- Most of the options are case-insensitive, Ex: -m PdFinFo
- File and folder names with spaces should be quoted or escaped
- The scaling is centered and using a scale bigger than 1.0 may
result on cropping parts of the PDF
- For detailed paper types information, use: pdfscale -p
