IEAutomaticallyRotateImageFile

Declaration

function IEAutomaticallyRotateImageFile(const Filename: string): integer;

Description

Digital cameras will generally store the correct orientation of an image when the camera is rotated to take a portrait photo. This function calls EXIF_Orientation to retrieve the desired orientation for a JPEG camera image and then calls JpegLosslessTransform2 to losslessly rotate it.
If ConservativeCheck is true it performs some further checking to ensure the orientation data is accurate (e.g. to avoid problems where the photo has already been rotated in another program).

Note: You must add the iexHelperFunctions unit to your uses clause

Example

// Rotate MyImage.jpeg if it is not correctly oriented
IEAutomaticallyRotateImageFile('D:\MyImage.jpeg', True);
