Tiff Library To Read Xsi Images

[mmeijer]

I'm trying to read a .tif image from XSI that contains
floating point RGBE data. ie. 32r + 32b + 32g + 32a

I haven't had any luck using devIL which uses libTiff.
It seems to be able to read some data from the header,
but devIL returns IL_LIB_TIFF_ERROR.

Does XSI have an API for working with their image formats?

thanks for any insight
