UISprite's scale can't be saved

[maoguo.zhang]

Hi,
I've downloaded the new version NGUI 2.6.3. I got a new problem with UISprite.
My sprite's orginal size is 213*211. I set the scale with 106*106 in the inspector, but this can't be saved and auto change to 213*211 after saving the scene.

Nothing in NGUI will resize your sprite for you when you save the scene. Check other scripts you have on it.

scale.x = Mathf.RoundToInt(rect.width * pixelSize) * Mathf.Sign(scale.x);
scale.y = Mathf.RoundToInt(rect.height * pixelSize) * Mathf.Sign(scale.y);
scale.z = 1f;
cachedTransform.localScale = scale;

If sprite type is simple, MakePixelPerfect will reset the scale to its actual pixel size.

You didn't mention using an image button. Yes, image button forcefully changes the size of your sprite to make it pixel-perfect when it changes sprites -- and this is the intended behaviour. You shouldn't stretch simple sprites, it just causes them to look blurry and distorted. Consider using a sliced sprite instead.
