| Name | Explanation |
|---|---|
| Handle | EXIF format raw image data |
| ExifInfo | The structure (user-defined type) containing the retrieved Exif information |
Return Value
Returns True (nonzero) if successful. Returns False (0) if unsuccessful.
Explanation
The IKJpegExifInfoMem function retrieves information about the main image and the thumbnail image from Exif format raw image data.
If successful, the retrieved values are set into the ExifInfo member variables. Because the thumbnail image handle is set into ThumbImageInfo.ThumbImageHandle, please be sure to free it from the memory using the IKFreeMemory function. For details about the EXIF_INFO structure, please refer to the explanation of the EXIF_INFO member variables in the Ik10File.dll, Ik10FileA.dll, Ik10File64.dll, Ik10File64A.dll section.
To load the primary image of an Exif(JPEG) file please use the IKFileLoad or IKJpegFileLoad function.
Except for the fact that the raster image is loaded from raw image data, this function operates in the same way as the IKJpegExifInfo function.
[Regarding the retrieved information]
The ImageKit retrieves Exif(JPEG) image infromation by executing the IKJpegExifInfoMem function. It should be noted that even though this function is properly executed, because of variations in the features of different digital camera equipment and the subsequent differences in the quality of images, not all information can be retrieved in every case. For more information, please refer to Japan Electronic Industry Development Association, "Digital Still Camera Image File Format Standard (Exchangeable image file format for Digital Still Camera: Exif)"Version 2.1, June 1998.
