<!--l. 427--><p class="noindent" >Once you have assembled a good reflectogram, you will
want to print it, or to use it in other computer programs. The
best way to do this is to save the final image in TIFF or
JPEG format, and then load it into the new application —
see <span
class="cmsy-10"></span><a
href="nipguidese10.html#x18-290004.2">4.2<!--tex4ht:ref: sec:loadsave --></a>.
<!--l. 432--><p class="indent" > There are a couple of points to bear in mind: first, like
any image, reflectograms look best on paper if you
sharpen them up a little first. Click on <span
class="phvr7t-x-x-80">Filter </span>/ <span
class="phvr7t-x-x-80">Convolution </span>/
<span
class="phvr7t-x-x-80">Custom Convolution</span>, right click on the matrix button, select
<span
class="phvr7t-x-x-80">Replace from file</span>. Double Click on the second or lower
<span
class="phvr7t-x-x-80">data </span>directory listed in the left hand column to enter
<span
class="phvr7t-x-x-80">nip2</span>’s main data directory. Change the <span
class="phvr7t-x-x-80">Image type select </span>/
option to <span
class="phvr7t-x-x-80">All FIles (*) </span>and then select and load <span
class="phvr7t-x-x-80">rachel.con</span>.
This will usually produce an approprioatly sharpened
reflectogram.
<!--l. 441--><p class="indent" > Secondly, you will need to try several prints with
different contrasts and brightnesses to get a good match
between the paper and the screen, try <span
class="phvr7t-x-x-80">Image </span>/ <span
class="phvr7t-x-x-80">Levels </span>/ <span
class="phvr7t-x-x-80">Linear</span>.
You may even want to fiddle with the gamma, try <span
class="phvr7t-x-x-80">Image </span>/
<span
class="phvr7t-x-x-80">Levels </span>/ <span
class="phvr7t-x-x-80">Power</span>.
<!--l. 446--><p class="indent" > Finally, you may not need a full resolution image. For
almost all printers there’s no point going over about
300 dpi (dots per inch), or about 3000 by 2000 pixels
for an A4 page. To reduce the size of an image, use
one of the functions listed under <span
class="phvr7t-x-x-80">Resize </span>/ <span
class="phvr7t-x-x-80">Transform </span>/
<span
class="phvr7t-x-x-80">Resize</span>.
