QPx_FlipPicture

QPx_FlipPicture(pictVar; pictVar):error
	pictVar	Picture	Picture variable
	flipMode	Longint	How the picture should be flipped
	error	Longint	Error result

The source picture is passed in the pictVar parameter. The source picture may be compressed or uncompressed. The flipped picture is also returned in the pictVar parameter and is always uncompressed. If an error occurs, pictVar is set to an empty picture.

The flipMode parameter denotes how the picture will be flipped. flipMode accepts the following constants and values:

Example

   // Flip gOriginalPicture horizontally and get
   // the result in gFlippedPicture

C_PICTURE($pict)
C_LONGINT($error;$flipMode)

$pict:=gOriginalPicture

$flipMode:=qpx_FlipHorizontal

$error:=QPx_FlipPicture ($pict;$flipMode)

If ($error=qpx_noErr)
   
   gFlippedPicture:=$pict
   
End if
