9NVIEW
10=====
11
12Nview is a multi-format image viewer.
13
14  Type nview -help for available options.

17About Nview for PC under DOS:
18-----------------------------
19
20  Nview is VESA compatible and works in 8,15,16 bits and truecolor mode.
21    The only mode available is 320x200x8 if your video card doesn't
22    support Vesa mode.
23 
24  For a complete description of the available modes on the display, type
25    nview -help (and use it with -d option's)
26 
27  For example with my Diamond S3 864, "nview -d3 back.gif" use the 640x480x15 display.
28 
29  With the -p<width>x<height>x<bits>, you take the best display that matches the arguments.
30    (Example: nview -p640x480x24 back.gif)
31    -p0x0x0 choose the best display for the bitmap.
32
33
34About Nview for X Window:
35--------------------------------------
36
37  Nview displays bitmaps on the default visual. You can use
38    -visual id (id is the visual number seeing with nview -help).
39 
40  By default, Nview display the bitmap and wait for a mouse click or the Escape key.
41    With the -w option, Nview create one window per bitmap.
42
43  Nview works with pipe, in this case the input format must be specified:
44    cat img.tga | nview -f2 stdin
45

47NCONVERT
48========
49
50Nconvert is the multi-format commandline image converter for Win32, DOS, OS/2, and other platforms.
51
52  Type "nconvert -help" for available options.
53
54  Type "nconvert -help > nchelp.txt" to save the help text into the file "nchelp.txt".
55
56  To convert files to a specific format, type for example :
57      nconvert -out 5 file1.pic file2.jpg file3.tga
58    or
59      nconvert -out tiff file1.pic file2.jpg file3.tga
60 
61  With a resize :
62      nconvert -out jpeg -ratio -resize 480 0 *.jpg
63      nconvert -out jpeg -resize 640 480 *.jpg
64 
65  The input format is not necessary, it will be autodetected. If a problem occurs, use the -in option.
66 
67  Nconvert is able to transform images while converting:
68
69    * To convert GIF files to JPEG files :
70        nconvert -out jpeg -truecolors *.gif
71   
72    * To convert JPEG files to GIF files :
73        nconvert -out gif -dither -colors 256 *.jpeg
74   
75    * To resize :
76        nconvert -out png -resize 510 230 *.jpeg
77        nconvert -out png -ratio -resize 510 0 *.jpeg
78        nconvert -out png -ratio -resize 0 510 *.jpeg
79        nconvert -out png -resize 200% 200% *.jpeg
80   
81  You can use it with images sequences.
82    For example, to convert the files file00.pic, file01.pic, ..., file10.pic and
83      we convert to jpeg format with the name pattern res0.jpg, res1.jpg, ... type :
84        nconvert -out jpeg -n 1 10 1 -o res#.jpg file##.pic
85
86  You can use % to specify source filename in dest filename.
87    For example, nconvert -out jpeg -o result_%.jpg file.tga
88      creates a file named result_file.jpg
89
90    Note for windows users: in batch files you must write %% instead of %. To bypass this problem, you can use a nconvert script instead of a batch file.
91
92  You can control nconvert with a script, performing multiple sets of conversions on multiple sets of files, example:
93
94    ### -out png -rtype lanczos -resize 200% 150%
95
96    screenshot1.bmp
97    screenshot2.bmp
98    screenshot3.bmp
99
100    ### -out gif -rtype lanczos -resize 500% 500% -oil 10 -colours 32
101
102    F:\icons\smile.bmp
103   
104    ### -out bmp -rtype lanczos -resize 30% 30% -oil 2 -rotate_flag smooth -rotate 45
105
106    selfportrait.png
107    mydog.png
108   
109    Save this into a text file, for example "nc.txt", and then run nconvert with this file as the only parameter: "nconvert nc.txt" . 
110
111Limitations:
112
113  Add text feature uses the Win32 API and is avaiable on Win32 only.
114
115  Some exotical image formats use external DLL's and are available on Win32 only.
116
117  When using a script file, avoid multiple spaces in the conversion definitions, they confuse the parser.
118
119  Converting huge images, or scaling up to a huge size requires much memory and may not always work.     
120
121Notes for DOS users:
122
123  Since v4.90, nconvert is supported for DOS again. Is is a 32-bit DOS application, using the "DOS/32A Extender".
124
125  Also the NVIEW picture viewer had a DOS version, but was discontinued in 2002 at version 3.87. It is available bundled with old nconvert 3.87.
