In other words, a capital M is very dark, a +period is very light, and a space is white. +.PP +Obviously, \fBasciitopgm\fP assumes a certain font in assigning +a brightness value to a character. +.PP +\fBasciitopgm\fP considers ASCII control characters to be all white. For +a lower case character, It assigns a special brightnesses which has nothing to +do with what it looks like printed. +\fBasciitopgm\fP takes the ASCII character code from the lower 7 bits +of each input byte. But it warns you if the most significant bit of +any input byte is not zero. +.PP +The output image is \fIheight\fP pixels high by \fIwidth\fP pixels wide, +truncating and padding with white on the right and bottom as necessary. +.PP +The \fIdivisor\fP value is an integer (decimal) by which the +blackness of an input character is divided. You can use this to +adjust the brightness of the output: for example, if the image is too +bright, increase the divisor. +.PP +In a sort of reminiscence of Fortran line printer carriage control, +where a line starts with \fB+\fP (plus), \fBasciitopgm\fP combines it +with the previous row of output instead of generating a new row. This +allows a larger range of gray values. (In Fortran carriage control, the +first character of every line sent to the printer tells how much to advance +the paper, with \fB+\fP meaning not at all, so that the rest of the +characters on the line overstrike the ones already on the paper. What +\fBasciitopgm\fP does is rather different in that \fBasciitopgm\fP does not +reserve the first character of every line that way. If the first character is +anything but \fB+\fP, \fBasciitopgm\fP considers it just to be first +character of the image. +.PP +If you're looking for something that creates an image of text, +with that text specified in ASCII, that is something quite different. +Use \fBpbmtext\fP for that. + +.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 +\&), \fBasciitopgm\fP recognizes the following +command line option: + + +.TP +\fB-d\fP \fIdivisor\fP +Specify the value by which the blackness of an input character is +divided.
