20 This program is part of Netpbm(1).
21 pamx displays a Netpbm image in an X Window System window. It is like
23 a very simple version of the classic X image viewer xloadimage.
24 If you don't specify the input file netpbm_file, the input is from
26 Standard Input. The input image can be any Netpbm image format. If
27 the input is a multi-image stream, pamx ignores all but the first
28 image.
29 pamx is not the best choice for general purpose viewing of images,
31 because it is a traditional simple Netpbm building block. It is a good
32 thing to build into other programs and can be useful for debugging more
33 complex systems, but you can get much more powerful viewers that can
34 display Netpbm images. For example, xloadimage, xli, xzgv, and any web
35 browser.
36 The initial window is at most 90% of the size of the display unless the
38 window manager does not correctly handle window size requests or if
39 you've used the -fullscreen option. You may move the image around in
40 the window by dragging with the first mouse button. The cursor will
41 indicate which directions you may drag, if any. You may exit the win‐
42 dow by typing 'q' or control-C when the keyboard focus is on the win‐
43 dow.
44 ppmsvgalib is a similar program that displays an image on a Linux sys‐
46 tem without the need for the X Window System.
47
51 pamx uses the resource class name Xloadimage for window managers which
52 need this resource set. This is, of course, the same resource class
53 that the conventional viewer program xloadimage uses.
54
57 All options can be abbreviated to their shortest unique prefix. You
58 may use two hyphens instead of one to designate an option. You may use
59 either white space or an equals sign between an option name and its
60 value.
61 -border=color
65 This sets the background portion of the window which is not cov‐
66 ered by any images to be color.
67 -display=display_name
70 This names the X display in which to put the window. E.g. 0:0.
71 -fit Force image to use the default visual and colormap. This is
74 useful if you do not want technicolor effects when the colormap
75 focus is inside the image window, but it may reduce the quality
76 of the displayed image.
77 -fullscreen
80 Use the entire screen to display the image.
81 -geometry=WxH[{+,-}X{+,-}Y
84 This sets the size and position of the window in which pamx dis‐
85 plays the image.
86 By default, the window size exactly matches the image size,
88 except that if you don't specify -fullscreen, the maximum is 90%
89 of the screen dimensions.
90 -install
93 Forcibly install the image's colormap when the window is
94 focused. This violates ICCCM standards and only exists to allow
95 operation with naive window managers. Use this option only if
96 your window manager does not install colormaps properly.
97 -pixmap
100 Force the use of a pixmap as backing-store. This is provided
101 for servers where backing-store is broken (such as some versions
102 of the AIXWindows server). It may improve scrolling performance
103 on servers which provide backing-store.
104 -private
107 Force pamx to use of a private colormap. By default, pamx allo‐
108 cates colors shared unless there are not enough colors avail‐
109 able.
110 -verbose
113 Causes pamx to print various information about what it's doing
114 to Standard Error.
115 -visual=visual_name
118 Force the use of a specific visual type to display an image. By
119 default, pamx tries to pick the best available image for a par‐
120 ticular image type. The available visual types are: Direct‐
121 Color, TrueColor, PseudoColor, StaticColor, GrayScale, and Stat‐
122 icGray. You may use the shortest unique prefix of these names,
123 and case is not significant.
124 -background=color
127 Use color as the background color instead of the default (usu‐
128 ally white but this depends on the image type) if you are trans‐
129 ferring a monochrome image to a color display.
130 -foreground=color
133 Use color as the foreground color instead of black if you are
134 transferring a monochrome image to a color display. You can
135 also use this to invert the foreground and background colors of
136 a monochrome image.
137 -title=text
140 Set the title bar title of the window. Default is the file name
141 of the input file, or 'stdin' if the image is from Standard
142 Input.

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