pbmpage - create a one page test pattern for printing SYNOPSIS
pbmpage [-a4] test_pattern DESCRIPTION
pbmpage generates a one page test pattern to print on a sheet of paper, for use in calibrating a printer. The test pattern in is PBM for- mat. pbmpage produces an image intended for 600 dots per inch printer resolution. If you are printing on an HP PPA printer, you can convert the output of this program to a stream that you can feed to the printer with pbm- toppa. Bear in mind that when you print the test pattern, you are testing not only the printer, but any converter or driver software along the printing path. Any one of these components may adjust margins, crop the image, erase edges, and such. If, due to addition of margins, the printer refuses to print the image because it is too big, use pnmcut to cut the right and bottom edges off the test pattern until it is small enough to print. test_pattern is the number of the test pattern to generate, as follows. The default is 1. 1 A grid ruled in numbers of pixels. The outermost rules are exactly at the edges of the paper. 2 A vertical line segment, one pixel wide, extending 1/2" up from the exact center of the page. 3 Two diagonal line segments, one starting at the upper left corner of the page, the other starting from the lower left corner of the page. Both extend 1/2" toward the center of the page at 45 degrees. OPTIONS
-a4 Generate an image for A4 (European) paper. Without this option, pbmpage generates an image for US standard paper (8 1/2" wide x 11" high). SEE ALSO

pnmtops - convert portable anymap to PostScript SYNOPSIS
pnmtops [-scale s] [-dpi n] [-imagewidth n] [-imageheight n] [-width=N] [-height=N] [-equalpixels] [-turn|-noturn] [-rle|-runlength] [-nocenter] [-nosetpage] [pnmfile] All options can be abbreviated to their shortest unique prefix. You may use two hyphens instead of one. You may separate an option name and its value with white space instead of an equals sign. DESCRIPTION
Reads a Netpbm image as input. Produces Encapsulated PostScript as output. If the input file is in color (PPM), pnmtops generates a color PostScript file. Some PostScript interpreters can't handle color Post- Script. If you have one of these you will need to run your image through ppmtopgm first. If you specify no output dimensioning options, the output image is dimensioned as if you had specified -scale=1.0, which means aproximately 72 pixels of the input image generate one inch of output (if that fits the page). Use -imagewidth, -imageheight, -equalpixels, -width, -height, and -scale to adjust that. OPTIONS
-imagewidth -imageheight Tells how wide and high you want the image on the page, in inches. The aspect ratio of the image is preserved, so if you specify both of these, the image on the page will be the largest image that will fit within the box of those dimensions. If these dimensions are greater than the page size, you get Postscript output that runs off the page. You cannot use imagewidth or imageheight with -scale or -equalpixels. -equalpixels This option causes the output image to have the same number of pixels as the input image. So if the output device is 600 dpi and your image is 3000 pixels wide, the output image would be 5 inches wide. You cannot use -equalpixels with -imagewidth, -imageheight, or -scale. -scale tells how big you want the image on the page. The value is the number of inches of output image that you want 72 pixels of the input to generate. But pnmtops rounds the number to something that is an integral number of output device pixels. E.g. if the output device is 300 dpi and you specify -scale=1.0, then 75 (not 72) pixels of input becomes one inch of output (4 output pixels for each input pixel). Note that the -dpi option tell pnmtops how many pixels per inch the output device generates. If the size so specified does not fit on the page (as measured either by the -width and -height options or the default page size of 8.5 inches by 11 inches), pnmtops ignores the -scale option, issues a warning, and scales the image to fit on the page. -dpi This option specifies the dots per inch of your output device. The default is 300 dpi. In theory PostScript is device-independent and you don't have to worry about this, but in practice its raster rendering can have unsightly bands if the device pixels and the image pixels aren't in sync. Also this option is crucial to the working of the equalpixels option. -width -height These options specify the dimensions of the page on which the output is to be printed. This can affect the size of the out- put image. The page size has no effect, however, when you specify the -imagewidth, -imageheight, or -equalpixels options. These options may also affect positioning of the image on the page and even the paper selected (or cut) by the printer/plotter when the output is printed. See the -nosetpage option. The default is 8.5 inches by 11 inches. -turn -noturn These options control whether the image gets turned 90 degrees. Normally, if an image fits the page better when turned (e.g. the image is wider than it is tall, but the page is taller than it is wide), it gets turned automatically to better fit the page. If you specify the -turn option, pnmtops turns the image no matter what its shape; If you specify -noturn, pnmtops does not turn it no matter what its shape. -rle -runlength These identical options specify run-length compression. This may save time if the host-to-printer link is slow; but nor- mally the printer's processing time dominates, so -rle makes things slower. -nocenter By default, pnmtops centers the image on the output page. You can cause pnmtops to instead put the image against the upper left corner of the page with the -nocenter option. This is useful for programs which can include PostScript files, but can't cope with pictures which are not positioned in the upper left corner. For backward compatibility, pnmtops accepts the option -center, but it has no effect. -nosetpage pnmtops normally generates a "setpagedevice" directive to tell the printer/plotter what size paper to use (or cut). The dimensions it specifies on this directive are those selected or defaulted by the width and height options or defaulted. If you don't want a "setpagedevice" directive in the output, specify -nosetpage. This can be useful if your printer chokes on this directive, which has not always been defined in Postscript, or you want to fake out the printer and print on one size paper as if you're printing on another.
