ReplacePixels replaces the pixels of the image with p . The given p must represent RGBA pre - multiplied alpha values . len ( p ) must equal to 4 * ( image width ) * ( image height ) . ReplacePixels may be slow ( as for implementation this calls glTexSubImage2D ) . When len ( p ) is not appropriate ReplacePixels panics . When the image is disposed ReplacePixels does nothing . ReplacePixels always returns nil as of 1 . 5 . 0 - alpha .
