Can I rotate an Image 180 Degrees with Freeimage

[PAUL SIMM]

I need to turn upside down scanned images. Does TImage have the posibility?

Paul,

you can use these functions to rotate images with FreeImage

Code: Select all  Expand view

DLL32 STATIC FUNCTION FIRotate ( hDib AS LONG, nAngle AS _DOUBLE ) AS LONG;
      PASCAL FROM "_FreeImage_RotateClassic@12" LIB hLib

DLL32 STATIC FUNCTION FIRotateEX ( hDib AS LONG, nAngle AS _DOUBLE, x_Shift AS _DOUBLE,y_Shift AS _DOUBLE,;
                                   x_Orig AS _DOUBLE, y_Orig AS _DOUBLE, lMask AS BOOL ) AS LONG;
      PASCAL FROM "_FreeImage_RotateEx@48" LIB hLib

I don´t know, you can look in the manual of freeimage if such a feature is supported
