a simple example (I did have a little time on my hands :-)):

-----<snip>-----
#version 3.7;

global_settings {assumed_gamma 1}

#declare pigment_ = pigment {
  image_map {
    png "tinai.png"
    once
    map_type 0
    interpolate 2
  }
  scale <2.048,1.519,1>
};

#declare box_ = box {
  0, <2.048,1.519,.1>
  texture {
    pigment {pigment_}
    finish {ambient 0}
  }
};

#declare line_ = cylinder {0,<2.048,0,0>,.05 no_shadow};

light_source {<-1,1,-1>*1e3 color srgb 1 parallel}

camera {
  location <1,.75,-5>
  right x * (4/3)
  up y
  angle 35
  look_at <1,.75,0>
}

object {box_ translate <0,0,1>}

object {line_ pigment {color rgb x} translate <0,.5,0>}
-----<snip>-----

note that the image dimension (2048x1519) and such should all be stored in
variables, "magic numbers" in the code invariably lead to more work)
