exrenvmap - for creating OpenEXR environment maps.
[options] infile outfile
This manual page documents briefly the exrenvmap
command. This manual
page was written for the Debian distribution because the original program does
not have a manual page.
converts OpenEXR latitude-longitude environment maps into
cube-face environment maps or vice versa.
- produces a ONE_LEVEL output file (default)
- produces a MIPMAP_LEVELS output file
- the output file will be a cube-face environment map
- the output file will be a latitude-longitude environment
- -w x
- sets the width of the output image to x pixels (default is
256). The height of the output image will be x*6 pixels for a cube-face
map, or x/2 pixels for a latitude-longitude map.
- -f r n
- sets the antialiasing filter radius to r (default is 1.0)
and the sampling rate to n by n (default is 5 by 5). Increasing r makes
the output image blurrier; decreasing r makes the image sharper but may
cause aliasing. Increasing n improves antialiasing, but generating the
output image takes longer.
- -t x y
- sets the output file's tile size to x by y pixels (default
is 64 by 64)
- -p t b
- if the input image is a latitude-longitude map, pad the
image at the top and bottom with t*h and b*h extra scan lines, where h is
the height of the input image. This is useful for images from 360-degree
panoramic scans that cover less than 180 degrees vertically.
- sets level size rounding to ROUND_DOWN (default)
- sets level size rounding to ROUND_UP
- -z x
- sets the data compression method to x
(none/rle/zip/piz/pxr24, default is zip)
- verbose mode
- prints these options
