Light Image Resizer - Command Line Switches / Parameters
=============================================================================

Light Image Resizer can be run by command line. Please refer to the 
following examples and reference.

---------------------
Single file or folder
---------------------

To process a single file or folder, simply use the following syntax:

  resize.exe <File/Folder> [Options]

  Example:
  resize.exe c:\photos /profile=original /format=bmp /run

The example above will load all supported image files from the c:\photos 
folder and create copies of them in bitmap format (BMP) while keeping the 
original dimensions.

You can also use wildcards to load specific file types from a folder. If you 
want to convert all bitmap images from a folder to PNG format:

  Example:
  resize.exe "c:\my images\*.bmp" /profile=original /format=png /run

Note: If a path contains spaces, it needs to be wrapped in quotes, like this:
"c:\my photos"
This applies to all parameters where values may contain spaces!


--------------
Multiple files
--------------

You can process several files in one operation. Make sure to use quotes if 
needed (as explained above):

  resize.exe <Filename1> <Filename2> ... [Options]

  Example:
  resize.exe "c:\my photos\image1.jpg" "c:\my photos\image2.jpg" /profile=desktop /run

Note: The maximum number of characters in a command line may be limited. 
If you want to process a large amount of files, or path names are very long, 
please consider using a file list (please see next section for details).


---------
File list
---------

To process large numbers of files at once, we recommend to use a file list. 
Basically a simple text file, which contains the full path for each image 
file (separated by line breaks). The command line uses this syntax:

  resize.exe /fl=<Filename> [Options]

  Example:
  resize.exe /fl="c:\my path\filelist.txt" /w=800 /h=600 /action=original /run

  Content of filelist.txt:
  c:\photos\image1.jpg
  c:\photos\image2.jpg
  c:\photos\image3.jpg

The example above will load the 3 image files specified in the file list and 
resize them to 800 x 600 pixels, replacing the original files.


----------------------
Exit code / error code
----------------------

The application will return one of the following error codes on exit:

  0: All files were processed successfully
  1: Error(s) occurred during processing
  2: Warning(s) occurred during processing
