How to Convert Sprite into Texture

Question

I Have image with a sprite and i want to change this image sprite to Texture so that I can assign it to the material And i don't want to keep multiple copies for each image as a sprite and texture.

Is there any way to change sprite to texture at run time?

Answer 1

// assume "sprite" is your Sprite object
 var croppedTexture = new Texture2D( (int)sprite.rect.width, (int)sprite.rect.height );
 var pixels = sprite.texture.GetPixels(  (int)sprite.textureRect.x, 
                                         (int)sprite.textureRect.y, 
                                         (int)sprite.textureRect.width, 
                                         (int)sprite.textureRect.height );
 croppedTexture.SetPixels( pixels );
 croppedTexture.Apply();

this should work for you. you can follow this thread for more info: https://answers.unity.com/questions/651984/convert-sprite-image-to-texture.html

For just converting Image's sprite To Texture use this:

Image.sprite.texture

And this will do the Job.
