i'm trying to read an hdr file using hdrread, here is the code:
hdr_input = hdrread('untitled.hdr');
the error meaasge is "Not a Radiance file.", hdrread>readHeader (line 67)
I'm trying to find out why.
the hdr image I got is from a Blender model, I see when I set the background color to black or transparency, it will output the error message.
If the background color is another color or little brighter, then the image can be read by MATLAB.
Any help would be appreciated.
