16 All options can be abbreviated to their shortest unique prefix. You
18 may use two hyphens instead of one to designate an option. You may use
19 either white space or an equals sign between an option name and its
20 value.

24 This program is part of Netpbm(1).
25 pamx displays a Netpbm image in an X Window System window. It is like
27 a very simple version of the classic X image viewer xloadimage.
28 If you don't specify the input file netpbm_file, the input is from
30 Standard Input. The input image can be any Netpbm image format. If
31 the input is a multi-image stream, pamx ignores all but the first
32 image.
33 pamx is not the best choice for general purpose viewing of images,
35 because it is a traditional simple Netpbm building block. It is a good
36 thing to build into other programs and can be useful for debugging more
37 complex systems, but you can get much more powerful viewers that can
38 display Netpbm images. For example, xloadimage, xli, xzgv, and any web
39 browser.
40 The program xwud (X Window Undump) is part of the X Window System and
42 performs the same basic display function, though with input in the spe‐
43 cial X Window Dump format (for which Netpbm has converters).
44 The initial window is at most 90% of the size of the display unless the
46 window manager does not correctly handle window size requests or if
47 you've used the -fullscreen option. You may move the image around in
48 the window by dragging with the first mouse button. The cursor will
49 indicate which directions you may drag, if any. You may exit the win‐
50 dow by typing 'q' or control-C when the keyboard focus is on the win‐
51 dow.
52 ppmsvgalib is a similar program that displays an image on a Linux sys‐
54 tem without the need for the X Window System.
55
59 pamx uses the resource class name Xloadimage for window managers which
60 need this resource set. This is, of course, the same resource class
61 that the conventional viewer program xloadimage uses.
62
66 -border=color
67 This sets the background portion of the window which is not cov‐
68 ered by any images to be color.
69 -display=display_name
72 This names the X display in which to put the window. E.g. 0:0.
73 -fit Force image to use the default visual and colormap. This is
76 useful if you do not want technicolor effects when the colormap
77 focus is inside the image window, but it may reduce the quality
78 of the displayed image.
79 -fullscreen
82 Use the entire screen to display the image.
83 -geometry=WxH[{+,-}X{+,-}Y
86 This sets the size and position of the window in which pamx dis‐
87 plays the image.
88 By default, the window size exactly matches the image size,
90 except that if you don't specify -fullscreen, the maximum is 90%
91 of the screen dimensions.
92 -install
95 Forcibly install the image's colormap when the window is
96 focused. This violates ICCCM standards and only exists to allow
97 operation with naive window managers. Use this option only if
98 your window manager does not install colormaps properly.
99 -pixmap
102 Force the use of a pixmap as backing-store. This is provided
103 for servers where backing-store is broken (such as some versions
104 of the AIXWindows server). It may improve scrolling performance
105 on servers which provide backing-store.
106 -private
109 Force pamx to use of a private colormap. By default, pamx allo‐
110 cates colors shared unless there are not enough colors avail‐
111 able.
112 -verbose
115 Causes pamx to print various information about what it's doing
116 to Standard Error.
117 -visual=visual_name
120 Force the use of a specific visual type to display an image. By
121 default, pamx tries to pick the best available image for a par‐
122 ticular image type. The available visual types are: Direct‐
123 Color, TrueColor, PseudoColor, StaticColor, GrayScale, and Stat‐
124 icGray. You may use the shortest unique prefix of these names,
125 and case is not significant.
126 -background=color
129 Use color as the background color instead of the default (usu‐
130 ally white but this depends on the image type) if you are trans‐
131 ferring a monochrome image to a color display.
132 -foreground=color
135 Use color as the foreground color instead of black if you are
136 transferring a monochrome image to a color display. You can
137 also use this to invert the foreground and background colors of
138 a monochrome image.
139 -title=text
142 Set the title bar title of the window. Default is the file name
143 of the input file, or "stdin" if the image is from Standard
144 Input.

155 pamx is by Bryan Henderson, in March 2006, based on xloadimage by Jim

190 pamx was new in Netpbm 10.34 (May 2006).
191 pamx is essentially based on the classic X displayer program xloadimage
193 by Jim Frost, 1989. Bryan Henderson stripped it down and adapted it to
194 Netpbm in March 2006.
195 The following features of xloadimage are left out of pamx, to be more
197 compatible with Netpbm's philosophy of simple building blocks. Note
198 that there are other programs in Netpbm that do most of these things:
199 · zoom in/out
202 · ability to accept formats other than Netpbm
204 · image transformations (brightening, clipping, rotating, etc)
206 · decompressing and other decoding of input
208 · ability to display on the root window
210 · slide show
212 pamx also differs from xloadimage in that it uses Libnetpbm.
215 There is virtually no code from xloadimage actually in pamx, because
217 Bryan rewrote it all to make it easier to understand.
