16-bit float data type.

Does anyone have any experience with using the 16-bit floating-point type in an application. This relatively new data type is used in computer graphics. It's defined by several specs: OpenEXR, DirectX and the new IEEE-754 2008 standard. At WinHEC 2008 Microsoft's Chas Boyd had a presentation evangelizing this data type. (I wasn't ...

OpenEXR image loading

I've started to load EXR images using OpenEXR. I have to get the RGB pixels using floating point type. For RGB images, there was no problem on loading, using this code: ImfInputFile *iFile = ImfOpenInputFile(filename); FrameBuffer fb; const Header &iHeader = iFile.header(); bool hasRed = false, hasGreen = false,...

I use the loop shown below to reverse the array but sometimes the program will quit and xcode will give me an EXEC_BAD_ACCESS error (Which I assume is the same as an access violation in msvc). It does not happen every...

Converting EXR image sequence to .MOV

I'm looking for a encoder that creates a Quicktime Movie (PhotoJpeg) from OpenEXR image sequences. Any help would be really appreciated ...
