byte[] to Texture2D ?

Hi all,
I am trying to convert a byte array to a Texture2D
I need to do the reverse of EncodeToPNG.

Any Ideas here.
I am using C#

 

Convert the byte[] array to a Color[] array and use SetPixels, perhaps?

The only way to decode a PNG currently short of implementing your own PNG encoder or making a plugin is to get the PNG using the WWW class. I did file a bug asking for DecodePNGFromBytes() and they listened, it just didn't happen yet is all.

Cheers,

If you have already decoded the PNG data to uncompressed RGBA, then I think Eric is probably right - colours are stored as floats, so you would need to convert the stored integer data.

If you mean that you have compressed PNG data (eg, read from a file) then you might find the attached files useful. The PNG decoder they implement is limited to 8-bit RGBA data (it can't handled indexed or monochrome PNGs or images with no alpha bytes) and is not battle tested but it might be enough to get you started.

However, it delivers the pixel data as RGBA bytes so you will still have to do what Eric described.

(By the way, the decoder relies on the SharpZip library, available from http://icsharpcode.net/OpenSource/SharpZipLib)

 

Sorry to revive this old thread, but I couldn't find a more recent one about this very same topic.

Is there now a method to DecodePNG? Included in Unity, I mean.

Thanks in advance.

EDIT: hey, wait a minute... silly of me. There is Texture2D.LoadImage(byte[] bytes) to achieve this. Sorry for the inconveniences!

Loads PNG/JPG image byte array into a texture.

 

Update for new versions of Unity: Use https://docs.unity3d.com/ScriptReference/ImageConversion.LoadImage.html

 

From which Unity version ImageConversion was introduced?

 

Unity 2017.1.
