You may separate an option +name and its value with white space instead of an equals sign. + +.UN description +.SH DESCRIPTION +.PP +This program is part of +.BR "Netpbm" (1)\c +\&. +.PP +\fBppmrough\fP generates a PPM image of the specified width, height, and +colors. \fBppmrough\fP tiles the image into semi-rectangular regions with a +ragged borders between them. It calculates the fluctuations with +pseudo-random numbers. +.PP +\fBppmrough\fP writes the PPM image to Standard Output. +.PP +The maxval of the output image is 255 (You can change this with +\fBpamdepth\fP). +.PP +Use the options \fB-left\fP or \fB-right\fP, respectively, to +make vertical borders, and \fB-top\fP or \fB-bottom\fP, +respectively, to generate horizontal borders inside the image. Each of +these options needs an integer value \fIpixels\fP that determines the +average distance of the interior border to the related edge of the +image. You may combine the \fB-left\fP, \fB-right\fP, \fB-top\fP, +and \fB-bottom\fP options to generate an image with more than one +border. The algorithm ensures that you can concatenate two images +produced with the same (i.e. \fB-left\fP) value without dislocations. +.PP +You specify the dimensions of the generated image with the +\fB-width\fP and \fB-height\fP options. +.PP +Use the \fB-bg\fP and \fB-fg\fP options to set the background +(margin) color and the foreground (interior) color, respectively. If +you don't specify any of the \fB-left\fP, \fB-right\fP, \fB-top\fP, +and \fB-bottom\fP options, all pixels are set to foreground color. +The defaults are white foreground and black background. +.PP +Use the \fB-var\fP option to control the "raggedness" of +the border. The less its value is the smoother the border is. You +can initialize the pseudo-random generator with the \fB-init\fP +option. +.PP +You could use \fBppmrough\fP with \fBppmtopgm\fP to create a PGM +transparency mask and use it to roughen up the edges of another image. + +.UN options +.SH OPTIONS +.PP +In addition to the options common to all programs based on libnetpbm +(most notably \fB-quiet\fP, see +.UR index.html#commonoptions + Common Options +.UE +\&), \fBppmrough\fP recognizes the following +command line options: + + +.TP +\fB-left=\fP\fIpixels\fP + Specifies the mean distance of the border from the left margin +(default: no border). + +.TP +\fB-right=\fP\fIpixels\fP +Specifies the mean distance of the border from the right margin +(default: no border). + +.TP +\fB-top=\fP\fIpixels\fP +Specifies the mean distance of the border from the top margin +(default: no border). + +.TP +\fB-bottom=\fP\fIpixels\fP +Specifies the mean distance of the border from the bottom margin +(default: no border). + +.TP +\fB-width=\fP\fIpixels\fP +Specifies the width of the image (default: 100). + +.TP +\fB-height=\fP\fIpixels\fP +Specifies the height of the image (default: 100). + +.TP +\fB-bg=\fP\fIcolorspec\fP +Background color. \fIcolorspec\fP is as described for the +.UR libnetpbm_image.html#colorname +argument of the \fBpnm_parsecolor()\fP library routine +.UE +\&.
