Best way to read 10+bit colour in a plugin?

[GadgetGames]

Hi All,

 

I'm a graphics developer coming over from making shaders in HLSL, one thing I'm really keen to try and make is a nice layered HDR (like, real HDR) bloom effect for some of my photos.

 

I've played around with BoltBait's tutorials and have a basic understanding of how to make a plugin now, but I'm still a bit unsure as to the "best" way for me to get pixel data that's greater than 8bpp and read it in a plugin. IE: If I have a 16bit .tif, and I select that and read a pixel's value in a standard plugin, will that pixel colour value be returned correctly in 16bit? So far I've found it hard to tell when just experimenting.

 

Thanks in advance,

-AB

Paint.NET's maximum color depth is 32bpp (8 bits for Red, 8 for Green, 8 for Blue, and 8 for Alpha).

 

If you need a greater color depth, I would recommend Photoshop.

You'll need to use another program.  Paint.NET only supports 8 bits per channel (32 bit images).

 

I suggest you use Krita or Photoshop.

if transparency isn't required, you could perhaps steal the alpha bits to go from rgb(8) to rgb(10) with 2 bits left. 

 

How viable this is i don't know.

If you want black and white 16 bits, I think that this is doable with a file export that export the value to B&W 16 bit. But, then you would need a plugins for that too.

 

Not viable, but that's the best you're going to get with higher depth in pdn.
