NVIEW
=====

Nview is a multi-format image viewer. 

  Type nview -help for available options. 


About Nview for PC under DOS:
-----------------------------

  Nview is VESA compatible and works in 8,15,16 bits and truecolor mode.
    The only mode available is 320x200x8 if your video card doesn't 
    support Vesa mode. 
  
  For a complete description of the available modes on the display, type
    nview -help (and use it with -d option's)
  
  For example with my Diamond S3 864, "nview -d3 back.gif" use the 640x480x15 display.
  
  With the -p<width>x<height>x<bits>, you take the best display that matches the arguments. 
    (Example: nview -p640x480x24 back.gif)
    -p0x0x0 choose the best display for the bitmap. 


About Nview for X Window:
--------------------------------------

  Nview displays bitmaps on the default visual. You can use 
    -visual id (id is the visual number seeing with nview -help).
  
  By default, Nview display the bitmap and wait for a mouse click or the Escape key. 
    With the -w option, Nview create one window per bitmap. 

  Nview works with pipe, in this case the input format must be specified: 
    cat img.tga | nview -f2 stdin


NCONVERT
========

Nconvert is the multi-format image converter. 

  Type nconvert -help for available options. 


  To convert files to a specific format, type for example :
      nconvert -out 5 file1.pic file2.jpg file3.tga
    or
      nconvert -out tiff file1.pic file2.jpg file3.tga
  
  With a resize :
      nconvert -out jpeg -ratio -resize 480 0 *.jpg
      nconvert -out jpeg -resize 640 480 *.jpg
  
  The input format is not necessary. If a problem occurs, use the -in option. 
  
  Nconvert is able to transform images while converting:

    * To convert GIF files to JPEG files : 
        nconvert -out jpeg -truecolors *.gif
    
    * To convert JPEG files to GIF files : 
        nconvert -out gif -dither -colors 256 *.jpeg
    
    * To resize :
        nconvert -out tga -resize 510 230 *.jpeg
        nconvert -out tga -ratio -resize 510 0 *.jpeg
        nconvert -out tga -ratio -resize 0 510 *.jpeg
        nconvert -out tga -resize 200% 200% *.jpeg
    
  You can use it with images sequences. 
    For example, to convert the files file00.pic, file01.pic, ..., file10.pic and 
      we convert to jpeg format with the name pattern res0.jpg, res1.jpg, ... type :
        nconvert -out jpeg -n 1 10 1 -o res#.jpg file##.pic

  You can use % to specify source filename in dest filename.
    For example, nconvert -out jpeg -o result_%.jpg file.tga
      creates a file named result_file.jpg
