Are you referring to the IHE MESA CPI test cases?

We got few Dicom images and 17 Testcases of them 104 are "With Presentation state" and with out presentation state.
We Also got a Dicom tool Version 3.0
I made the change to the given dicom image in dicom tool and compare it with the test case but unable to know the result image.
i wanted to know "when we apply the presentation state to the Dicom Image what could be the Result image" ...
E.g Test Case

Image :
SC image with SMTPE pattern(placed in bottom right hand corner), Rows 1280, cols 900, Bits allocated 8 bits stored 8, Pixel range 0 to +255 , Pixel representation in Unsigned, Photometric Interpretation is MONOCROME 2, no Luts.

PState:
Presentation Size Mode: SCALE TO FIT, Displayed Area Top Left Hand Corner 768\388, Displayed Area Bottom Right Hand Corner 1280\900, Presentation Pixel Aspect Ratio 1\1

Result:
Display should be a normal SMPTE pattern

I guess these test cases are from the 2004 release of the IHE MESA CPI Image Display Test.
We Also got a Dicom tool Version 3.0
If you are referring to the DICOMscope application, the current version is 3.6.0.
I made the change to the given dicom image in dicom tool and compare it with the test case but unable to know the result image.
What changes did you make, and why?
i wanted to know "when we apply the presentation state to the Dicom Image what could be the Result image" ...
The expected result is described in the test plan, usually it's a "normal SMPTE pattern". For some test cases, the expected result is provided as another DICOM images (with .res filename extension).
The expected result could also be visualized using the DICOMscope application (DICOM image + associated GSPS object) ...
