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 ...
Hi there! I'm currently working on a project with OpenEXR and I would like to implement some Blob detection algorithms. To do this I figured that I could use OpenCV as it says in the documentation that it can open OpenEXR format files. I have all the libraries installed and working as I've been doing other things. I open a simple jpg f...
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,...
Hello, I am loading an image using the OpenEXR library. This works fine, except the image is loaded rotated 180 degrees. 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...
I'm looking for a encoder that creates a Quicktime Movie (PhotoJpeg) from OpenEXR image sequences. Any help would be really appreciated ...
I am trying to build a certain library under cygwin (OpenEXR), and I get the following error: b44ExpLogTable.cpp:52:18: error: half.h: No such file or directory half.h is referenced using #include <half.h>, and is actually a part of another library I successfully run make/make install on previously. The question is -- when using #inc...
