Declaration

TIETIFFHandler = class;

Description

This class allows you to read all TIFF tags, edit/add tags and pages, delete pages, and finally save back the modified TIFF. TIETIFFHandler is an older class, so you may find it easier to work with TIEMultiBitmap.

Note: This class is unable to work with some OLD-JPEG tiff files. OLD-JPEG compression is no longer supported by the TIFF standard. You can use a TIEMultiBitmap to modify all TIFF images.

Demo

Examples

// add a custom tag (65000 with 'Hello World') at page 0
mytif := TIETIFFHandler.Create('input.tif');
mytif.SetValue(0, 65000, ttAscii, 'Hello World!');
mytif.WriteFile('output.tif');
mytif.free;

// delete second page (indexed 1) of a multipage tiff
mytif := TIETIFFHandler.Create('input.tif');
mytif.DeletePage(1);
mytif.WriteFile('output.tif');
mytif.free;

// insert a new page from an external file
mytif := TIETIFFHandler.Create('input.tif');
mytif.InsertPageAsFile('external.jpg', 0);
mytif.WriteFile('output.tif');
mytif.free;

// merge two tiff (even they are multipage files..)
mytif := TIETIFFHandler.Create('input-1.tif');
mytif.InsertTIFFFile('input-2.tif', mytif.PagesCount-1);
mytif.WriteFile('output.tif');
mytif.free;

// read tag 305 ('software')
mytif := TIETIFFHandler.Create('input-1.tif');
software := mytif.GetString(0, mytif.FindTag(0, 305));
mytif.free;
