Real vs Unity sprite dimentions discrepancy

Unity Engine
1

Hi all,

i got a very weird problem and hope someone knows the answer.

I have imported my sprites into Unity 4.7.0 with the following settings:
2738695--196031--sprite_import_settings.png

Then i check the dimentions of it in Unity and those don’t fit the real dimentions of the image. It brings a lot of very annoying problems.

So far, i have checked the following dimentions of the sprites (Real vs Unity):

258x185 vs 260x188
254x204 vs 256x204
325x255 vs 328x256
259x183 vs 260x184

What could cause this issue? Is there any simple and quick way to fix it?

Thanks a lot!

Best regards,
Alexander

If you set the Texture Type to “Advanced” you will see an “Extrude Edges” slider. This extends the sprite by a number of pixels as a buffer region for filtering and packing I think. That is likely the difference you’re seeing.

Thanks a lot for the reply jeffreyschoch. Finally, i got a chance to test your suggestion. Unfortunately this workaround didn’t help. After changing the sprites import settings to Extrude Edges = 0, the resolution values don’t change. The problem still persists.

Isn’t it possible that the compression resizes the picture to fit into its algorithm? I noticed almost all changes are from odd to even numbers. Check if it changes when set to Truecolor. Also these are some weird texture sizes.

Yah the compression may force multiples of 4x4 pixel groups.

I agree, you may want to keep your sprites in more uniform power-of-two resolutions, and then slice them in the Sprite Editor.
