I want to know that is there any way of resizing our texture to the size of a sprite in slimdx direct3d9 or directx9. That is if my image size is 1024x768 and sprite size is 500x500, how can i resize the image in slimdx to display it fully on the sprite without any cropping.

Make a standard quad or 2-triangle strip with UV coordinates:

[0,0]----[1,0]
  |        |
  |        |
[0,1]----[1,1]


Draw at:

[X,Y]-----------[X+500,Y]
  |                 |
  |                 |
[X,Y+500]----[X+500,Y+500]
