exrenvmap - for creating OpenEXR environment maps.


exrenvmap [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.

exrenvmap converts OpenEXR latitude-longitude environment maps into cube-face environment
maps or vice versa.


-o produces a ONE_LEVEL output file (default)

-m produces a MIPMAP_LEVELS output file

-c the output file will be a cube-face environment map (default)

-l the output file will be a latitude-longitude environment map

-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.

-d sets level size rounding to ROUND_DOWN (default)

-u sets level size rounding to ROUND_UP

-z x sets the data compression method to x (none/rle/zip/piz/pxr24, default is zip)

-v verbose mode

-h prints these options
