Re: How Does One Compile For Full Floating Point Format

Hi Fred,

the OpenEXR libraries simultaneously support all three pixel formats:
16-bit floating-point (HALF), 32-bit floating-point (FLOAT) and 32-bit
unsigned integer (UINT).  You don't need special build options or add-on
modules.

Application code can select pixel formats at run time and per per channel.
For example, an application can write a file with R, G and B channels in
HALF format and a Z channel in FLOAT format.

For more information on calling the OpenEXR libraries from your code,
including how to select pixel formats, see this document:
