I think the problem is with the output file.
==============================
Input_File_Name=myinput.pov
Output_File_Name=myoutput.tga
==============================
Well, I don't undersant how can I convert the files. In the Pov-Ray windows
code?

I have read this: "In addition to support for variable bit-depths, alpha
channel, and grayscale formats, PNG files also store the Display_Gamma value
so the image displays properly on all systems (see section "Display Hardware
Settings"). The hf_gray_16 global setting, as described in section
"HF_Gray_16" will also affect the type of data written to the output file."

I think I have to convert my file .pov to a .png
What do you think?
In the text box I put "+ua" and in the Pov code:
====================================
  background { White }
  camera {location <170, 11, -110>look_at  <180, -15, -16>}
  light_source { <170, -30, -100> color White}
======================================

Thank you very much,
Oleguer
