Hello. I started my own gui system and got some problems with rendering the images and their sizes.

I use dds format. When drawn in photoshop it looks perfect. For export i use nvidia dds plug-in and ABGR 128 bpp | floating point when exporting.

The problem is when rendered in my game it looks bigger which i seems cant control.
Here is the image when rendered in the game:
rendered

and the dds when opened in the dds viewer:
dds

Is this something from my code or from the image?

Is your backbuffer the same size as your client area? Are you using ID3DXSprite to draw the sprite?

You could always wait more than an hour and 20 minutes before bumping your post too

Yes it is the same size. Yes i use ID3DXSprite.
Here is my render function if it will be in any help:


 
 obj.sprite->Begin(D3DXSPRITE_ALPHABLEND);
 
 obj.sprite->Draw(obj.normalText,NULL,NULL,&obj.imagePosition,D3DXCOLOR(255,255,255,255));
 
 obj.sprite->End();

Can't see any difference in your images, which seem resized. Post 100% size images.

if you've changed the transform of the sprite object somewhere else in your project you need to load an identity matrix.
check D3DXSprite->SetTransform()

this may also be the result of the texture not being power of 2

Didnt work. Also i never change the transform.
And yes the texture dimensions are at power of 2.
