Subject: Re: Assign Multiloaded TIFF Graphic to other TIffGraphic fail
In reply to: Yosi Mazal-Tov 's message, "Assign Multiloaded TIFF Graphic to other TIffGraphic fail" on 19:24:26 12/04/02 Wed


Hi Yosi,

Assign is a method in the base TDibGraphic class and is designed from single page only. You need to handle this page by page.

I would recommend saving all the pages the pages to a TMemoryStream and then reloading in your destination. Use TDibGraphic.SaveToStream for the first page then AppendToStream for the subsequent pages. Then in the destinatation TTiffGraphic set MultiLoad to True and use LoadFromStream.

Best regards,

Michel


The easiest way to accomplish what you are trying to do is to save to a TMemoryStream and then load back. For example,

Stream := TMemoryStream.Create;
TifGraphic1.SaveToStream(Stream);
