Bug 3257

Summary: SDL_BITSPERPIXEL macro translations are incorrect
Product: SDL Reporter: Matthew Saint <mattsaintdev>
Component: *don't know*Assignee: Ryan C. Gordon <icculus>
Status: RESOLVED INVALID QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2    
Version: 2.0.4   
Hardware: x86_64   
OS: Windows (All)   

Description Matthew Saint 2016-02-08 16:29:31 UTC 
Unit SDL.pas;

SDL_BITSPERPIXEL()
SDL_PIXELLAYOUT()
SDL_PIXELORDER()
SDL_PIXELTYPE()
SDL_PIXELFLAG()

Macro conversions are incorrect and should not return a bool but an Integer or Cardinal.

Further the Result should be AND'd with the mask not equated.

e.g of correct

Function SDL_BITSPERPIXEL(X: Cardinal): Cardinal;
Begin
  Result := (X Shr 8) And $FF;
End;
