Greetings All,

Delphi 5.1 (Preparinging to convert to Delphi XE, once I have switched out Pegasus ImagXPress for ImageEn)

Using a TImageEnMView to display thumbnail pages in a multi-page tif and TImageEnVext to display the individual pages.

I need to give the user the ability to swap pages in a multi-page tiff. Generally it is to swap pages 2 and 3 so that page 3 now becomes page 2 and page 2 becomes page 3.

Does ImageEn have a built-in function to do this? If not does anyone have any code example on how to go about doing this?

Thanks,
Mike

Is something like this possible in

Take a look at TIETIFFHandler for MovePage... or just move the frame. There is a TIETIFFHandler demo in samples folder.

TIETIFFHandler.MovePage

Declaration

procedure MovePage(CurIndex, NewIndex:integer);


Description

Moves specified page to a new position.

or just move the frame:

TImageEnMView.MoveImage


Declaration

procedure MoveImage(idx:integer; destination:integer);

Description

Moves an image from the index position idx to destination position.
If the destination index is equal to or greater than the image count, the idx image is moved to the position immediately after the last image.

Example
// exchange the third and second image
// remember that the first image has an index of 0 so use 2, 1 not 3,2
ImageEnMView1.MoveImage(2, 1);
