MarkAt

Hint 1:

Please note, that some of the marks are displayed by using pixel graphics. These marks may be show up in an unfavorable way (only tiny dots, or several thin lines) when using WMF for large printouts, i.e. for high resolution printers. The following marks are concerned:     18  large shaded block     25  large bold cross

Hint 2:

Due to a bug in Delphi 2005 (.NET only) the filled symbols cannot be drawn correctly. This bug occurs only under the .NET environment, under Win32 the method MarkAt works as expected. As of January 2005, there is no known work-around for this bug. If you need the full palette of symbols, you have to use Win32.

Hint 3:

In order to select a mark interactively you should use the component TMarkSel
