Why my sprites don't display correctly ?

Here, http://img269.imageshack.us/img269/3249/screenywwu.jpg On the left is the simple sprite I've drawn in photoshop and on the right is the sprite rendered by directx. Notice they're both 5x5 pixels so I don't think any min/mag filters are being used. Why is my drawn sprite so different ? It's not even symmetric anymore That's the code I use CustomVertex.TransformedTextured[] vertices = new CustomVertex.TransformedTextured[4]; vertices[0].Position = new Vector4(x, y, 0f, 1f); vertices[0].Tu = 0f; vertices[0].Tv = 0f; vertices[1].Position = new Vector4(x, y + h, 0f, 1f); vertices[1].Tu = 0f; vertices[1].Tv = 1f; vertices[2].Position = new Vector4(x + w, y, 0f, 1f); vertices[2].Tu = 1f; vertices[2].Tv = 0f; vertices[3].Position = new Vector4(x + w, y + h, 0f, 1f); vertices[3].Tu = 1f; vertices[3].Tv = 1f; D.SetTexture(0, tex); D.VertexFormat = CustomVertex.TransformedTextured.Format; D.DrawUserPrimitives(PrimitiveType.TriangleStrip, 2, vertices);

Thanks ! It's better. Now it's symmetric
But it's still not the same image as my drawing:

What do you think is wrong ?

Seems like bilinear filtering or something.. try using point sampling and disable mipmaps. Are you drawing it in a 1:1 ratio, so that it's drawn at exactly 5x5 pixels, and you've just resized it after you took the screenshot?
