> Is it a small object that you resized to be bigger? If yes - then open the Animation Editor and remove the 1 pixel-wide transparent border around the object
but yeah it is a small object that i made bigger, but there is no transparent border.
I miss understood your problem... I think simple games is on the right track.
Control click here to remove the single pixel of padding - Which will be stretched if your drag resize your image.
I also believe smooth with try to make an image look as close as possible by blending pixels. Blending pixels with transparent can give you a semi see through look
