PictView32 1.14 - ultra-fast freeware image converter
Copyright (c) 1994-2003 Jan Patera, support@pictview.com

PictView can be called with parameters on the command line to convert images
between different file formats:

 PVW32Con.exe File [Target_fmt] [--o Path] [--tX] [--xXX] [--yXX] [--k] [--g]
  [--cXX | -cfName | --24 | --32] [--pXX] [--sXX] [--i] [--ta] [--tp] [--tsX]
  [--h] [--v] [--rXXX] [--jh] [--jqXX] [--jsX]

File - name and extension (may include a path) (wildcards may be used)
   of the file(s) to be converted.

Target_fmt - a switch from the following table describing the target format:
 -a TrueVision Targa TGA    -j JPEG                   -r SunRaster RAS
 -A PC Paint/Pictor PIC     -k PBM/PGM/PNM/PPM        -s ColorRIX SCX
 -c Dr.Halo/Dr.Genius CUT   -l Amiga IFF/ILBM         -S SKA Video renting box
 -C Autodesk Animator CEL   -n Silicon Graphics IMG   -t TIFF
 -e Intergraph Raster File  -o OS/2 BitMap            -u Utah RunLength Encoded
 -g GIF                     -p ZSoft PCX              -w Windows BitMap
 -i MS Windows Icon         -R Raw uncompressed data  -W Wireless BitMap WBMP

If no format is specified, only image info is displayed (no conversion)

 --cXXX   - Reduces color palette to XXX colors
 --cfName - Convert to color palette stored in file Name
 --cu     - Convert to uniform 216-color palette for web
 --24     - Convert to 24bit TrueColor
 --32     - Convert to 32bit TrueColor (with alpha)
 --g      - Convert to grayscale
 --i      - Create interlaced file (GIF)
 --o Path - Specifies output file name or path (if ended by \ or 
 --pXXX   - XXX is page/image of input file (1 is default), --pa for all pages
 --sX     - X is compression: 0:raw, 1:RLE, 2ackBits, 3:Huffman, 4ZW, 5:JPG
 --tXXX   - XXX specifies transparent color index in output GIF file
 --ta     - Append as a new page to multipage TIFF
 --tp     - Predict LZW-compressed TIFFs (usually smaller files)
 --tsXXX  - XXX is TIF strip size in KB (default 8, max 64, 0 for single strip)
 --h      - Horizontal mirror (left to right)
 --v      - Vertical mirror (top to bottom)
 --rXXX   - Rotation clockwise (XXX can be 90, 180, 270)

Resizing (rescaling) of images:
 --x, --y - XXX is target width and/or height in pixels
 --k      - Keep aspect ratio, if only one of --x and --y is specified

JPEG options:
 --jh     - Use high quality decoder (on read, slower)
 --jqXXX  - Output image quality (1 worst, 100 best, 75 default)
 --jsXXX  - Output subsampling (1: 1x1x1, 2: 2x1x1 - default, smaller files)
