procedure ResetInfo(ResetItems: TIEMetaInfoItems = []);


Clear the meta-data within the current image to reduce its file size.
You can use ContainsInfo to determine what meta-data your file contains.

Note: Clearing InputICCProfile or JPEG_MarkerList may change the display of JPEG files that make use of an ICC Profile.

If Values for ResetItems is [] then all items are cleared. Values for ResetItems:
Value Description
ierAnnotations Clears ImageEnAnnot and ImagingAnnot
ierDicomTags Resets DICOM_Tags and DICOM position info
ierEXIF Calls ResetEXIF
ierICC Resets InputICCProfile
ierIPTC Resets IPTC_Info
ierJPEGMarkers Clears JPEG_MarkerList. Note: Does not remove ICC Profile Marker unless ierICC is also included

ierOtherTextMeta Clears GIF_Comments, PNG_TextKeys, PNG_TextValues, TIFF_DocumentName, TIFF_ImageDescription, TIFF_PageName, IEN_Description, PDF Properties, TGA_Author, TGA_Descriptor, TGA_ImageName, PXM_Comments
