Posted: 02/21/2005 23:37:07 Just a note about how PDF components work. PDF is very similar to windows metafile - it contains commands like "draw text here", "draw rectangle here", etc. PDF components provides a Canvas where TRichView (more exactly, TRVReportHelper) can draw. Then they capture this drawing output and save it to PDF file. What's why they cannot, for example, convert RTF (or other file format) to PDF themselves. It's not a matter of simple format convesion. They need some engine drawing the document on canvas. TRichView can do it. PDF component quality depend on how many PDF commands (like "draw text here") they support, as well as how they support PDF-specific features. > Mike - sorry to bother you, but I wanted to ask your opinion of the pdf lib > you are using.
