#I use xwd/xpr (from the X11R5 dist.) and various programs of the |

#ppm-tools to print hardcopies of colored X windows. My problem is, |
|
I don't like xpr. It gives (at least, the X11R4 version does) louzy |
|
output: the hardcopy looks very grainy to me. |
|
Instead, I use pnmtops. This takes full advantage PostScript, and |
|
lets the printer do the dirty job of dithering a (graylevel) |
|
image to black and white dots. |
|
So: if you have a PostScript printer, try: |
|
xwdtopnm <xwdfile> | # convert to PPM |
|
[ppmtopgm |] # .. to graylevel for smaller file to print |
|
pnmtops -noturn | # .. to PostScript |
|
lpr # print |
|
pnmtops Has several neat options, but use them with care: |
|
If you want your image to be 4" wide, use: |
|
pnmtops -noturn -scale 100 -width 4 |
|
-noturn Prevents the image from being rotated (if it is wider than it |
|
is high) |
|
-width 4 Specifies the PAPER width (not the image width - see below) |
|
-scale 100 Is used because if the image is small, it may fit within a |
|
width less than 4", and will thus be printed smaller than 4" wide. |
|
If you first scale it up a lot, it will certainly not fit in 4", and |
|
will be scaled down by pnmtops automatically to fit the specified |
|
paper width. |
|
In short: pnmtops will scale an image down to fit the paper size, |
|
but it will not blow it up automatically. |
|
Hope this helps. |
