How do I get Original Size and Changed Size of Sprite

Suppose I have a character's walk Animation with 10 Frames

each frame has different height and width according to character's move

I did scale down Character Proportionally (i.e 30% size reduced)

Now i want to get the Original height & width of Each Frame

Is this Possible ?

If yes then How we can do this ?

Sprite.ImageWidth

Sprite.ImageHeight

This is I know but

When I have reduced size I want to get the original size, not reduced

Suppose Actual Dimension was 200(h) x 50(w)

when i reduced it to 50%

New dimension will be 100(h)x25(w)

Now How can I get old size 200x50

Sprite.ImageWidth

Sprite.ImageHeight

These are the texture size and are not the same as:

Sprite.Width

Sprite.Height

Thanks

I was never know this

Thank again to both of you
