Hello,

I did an image and I have to print in a 1200x900 cm poster. What resolution
should I use?

Thanks in advance,
Oleguer

forgive my non-metric upbringing, but isn't 1200x900 centimeters equal to
12x9 meters? that's freaking huge.

Yes, 12 meters and 90 cm. The high 12 meters and the width is 90 cm.

Oleguer

Ohhhhh, no, I'm sorry. That's 1'2 meters and 90 cm.
Really sorry.

You are ok.
1 mt = 100 cmt then 1200x900 cmt = 12x9 mt.

Anyway the resolution is more related to the printer resolution, if your
printer has by example a resolution of 300 dpi (dot per inch) and you image
is 1200x900 cm = to 472.4 x 354.3 inches then the image in pixels is =
141720 x 106290 or (1200/2,54*300)x(900/2,54*300). And yes, is freaking huge
:D

Salu2.

  POV-Ray can't render an image that big simply because the image file
would be too large.

  Well, the 32-bit version of POV-Ray can't. You'll have to use the 64-bit
version is a 64-bit system.

  But anyway, there was a mistake by one order of magnitude in the original
request, so the image only needs to be a hundred times smaller.

Often, for large images (over a feet whide or high, even more so for 
around a meter), you are assumed to look from some distance. Taking this 
into consideration, it can be possible to use a MUCH lower resolution 
and use rescaling when printing. Just look at advertisement in the metro 
(if your city have one), or street level billboards. If you look close, 
it's *VERY* grainy, but get's OK if you get back a few steps, even 1 
meter is generaly enough. It's very easy to print 100*100 dots for every 
1*1 pixel... and using error diffusion dithering, you may never notice 
that each pixel is repeated 100*100 times.
Remember that you can print a 72 DPI image at 1600 DPI, without 
shrinking it, it just have a lot of very fine dithering.

OK, the hard way is trace the image in printer resolution.
first translate from metric to inches: 1,2 mt = 47,24 inches // 0,90 mt =
35,43 inches
next step is use the printer resolution, let say for a 300 dpi printer
resolution: 47,24 inches = 14172 pixels // 35,43 inches = 10629 pixels.
(multiply the size in inches by the resolution in dpi)
then your ouput in pov need to be 14172 x 10629.

The easy way is render the image in a more reliable size without change the
relation w/h = 1.3333~ and scaling later at print. by example 2362 x 1772
pixels and scaling in a factor of 6 or 600%.

Sorry my ugly english, i do my best

Salu2.
