IERotateImageFile

Declaration

function IERotateImageFile(const FileName: string;
                           JpegQuality: Integer;
                           RotateAngle: Integer;
                           AntiAliasMode: TIEAntialiasMode = ierFast;
                           bCanUseLossless: Boolean = True;    
                           cBackgroundColor: TColor = clWhite): Boolean; overload;
function IERotateImageFile(const InFileName, OutFileName: string;
                           JpegQuality: Integer;
                           RotateAngle: Integer;
                           AntiAliasMode: TIEAntialiasMode = ierFast;
                           bCanUseLossless: Boolean = True;
                           cBackgroundColor: TColor = clWhite): Boolean; overload;

Description

Calls Rotate to rotate an image file and resave it (optionally to an alternative file). if bCanUseLossless is specified then JpegLosslessTransform2 is used where possible for JPEG files.

Note:
◼You must add the iexHelperFunctions unit to your uses clause
◼Consider use of AngleToImageEnRotateAngle
◼Delphi/C++ 2005 or newer is required

Example

// This will result in a lossless rotation
IERotateImageFile('D:\MyImage.jpg', 90, ierFast, True);
                                                                
// This will be a lossy rotation
IERotateImageFile('D:\MyImage.jpg', 45, ierFast, True, clBlack);
