Pulling arrayed data from Texture2D?
Say I have a Texture2D that I've loaded via the WWW class. If I wanted an an array containing the color data of that texture where should I turn? I've looked into the EncodePNG() function, which returns a byte list, and while that works for the most part I don't seem to understand how to use the information I get back. For example, if I have a 2x2px png (red, green, blue, then empty from top-left) I encode and debug print each byte, I get back 77 lines of debug, none of which contain a value of 255.
What I want, I guess, is a list of Vector4/Color data for each pixel in a Texture2D in some sensible order. Is this possible?
See Texture2D.GetPixes() and Texture2D.GetPixels32(). The first returns a Color array, the second returns a Color32 array. The array is 1D, so you have to calculate the pixel based on the width/height of the texture. If used on a texture in your assets folder, the texture must be marked as read/write enabled, and only specific formats are supported. I'm away from my computer, so I cannot test to make sure these functions work with dynamically loaded textures. There are a number of posts on GetPixels().
Just realized I never thanked you for your answer! THAN$$anonymous$$S! This is exactly what I wanted! = D
