[Résolu] Rotation d'image avec RotateCoordinates

[GallyHC]

Bonjour,

J’ai un peu de mal pour bien comprendre la lib « Vector ». J’aimerais juste faire une méthode de rotation d’image (avec ajustement de la taille de celle-ci).

Voilà ma routine actuelle :

Code : Tout sélectionner

Procedure.s ImageRotation(filename.s, filedest.s, angle.f)
  
  CompilerIf #PB_Compiler_Debugger
    Define.i itimer   = ElapsedMilliseconds()
  CompilerEndIf  
  
  Protected.s fileresult
  Protected.i entrysize = FileSize(filename)
  If entrysize <> -1 And entrysize <> -2 And entrysize > 0
    Protected.i image = LoadImage(#PB_Any, filename)
    If IsImage(image)
      Protected.d CosA, SinA
      Protected.i height, width, temp, img_w, img_h
  
      CosA    = Cos (Radian  (angle))
      SinA    = Sin (Radian  (angle))
      width   = ImageWidth   (Image )
      height  = ImageHeight  (Image )
      img_w   = Abs(height  * SinA) + Abs(width * CosA)
      img_h   = Abs(height  * CosA) + Abs(width * SinA)
  
      temp = CreateImage(#PB_Any, img_w, img_h, 24, #White)
      If IsImage(temp)
        If StartVectorDrawing(ImageVectorOutput(temp))
          VectorSourceColor(RGBA(255,255,255,255))
          TranslateCoordinates(0, 0)
          MovePathCursor    (0, 0, #PB_Path_Default)
          MovePathCursor    (width * 0.5, height * 0.5, #PB_Path_Default)
          RotateCoordinates (width * 0.5, height * 0.5, angle, #PB_Coordinate_User)
          MovePathCursor    (-width, -height, #PB_Path_Default)
          DrawVectorImage   (ImageID(image), 255, width, height)
          StopVectorDrawing ()
        EndIf
        If SaveImage(temp, filedest, #PB_ImagePlugin_JPEG, QualityCompress, 24)
          fileresult = filedest
        EndIf
        FreeImage(temp)
      EndIf
      FreeImage(image)
    EndIf
  EndIf
  
  CompilerIf #PB_Compiler_Debugger
    Debug "ROTATION : " + FormatDate("%hh:%ii:%ss", (ElapsedMilliseconds() - itimer) / 1000)
    Debug "FILENAME : " + filename
  CompilerEndIf
  ProcedureReturn fileresult

EndProcedure

merci d'avance, si quelqu'un peu m'aider.

Cordialement,

Bonjour,

Exact, bon va falloir que je comprenne maintenant le pourquoi.


Merci et cordialement,
