(my junk is not available anywhere because a. It's a mess I'm ashamed of :)
, and b. It doesn't have anything that isn't trivially available elsewhere )
My current hdr-rgb fix kludges a 4 byte hd-RGB into 3 bytes mantissa (r,g,b
as uint8s) and a 4th byte exponent (as int8) - and then squashes the 4th
byte into the A channel of the standard library color.NRGBA type -this
saves me some time as I can use a few standard library and additional
packages for post-work without too much hassles. I'll probably make a
proper color.Color type at somepoint though the required RGBA() method will
need to be somesort of logarithmic kludge
*I think some people might appreciate your work as a package too*. Maybe if
it color output the rendered image as a [][]struct{R,G,B float32 etc} for
ease of post-processing/image conversion that could well be useful to
others.
Keep up the good work. !
