A Worker provides a way for you to have code that runs on multiple CPU cores. A Worker achieves this by running its code in a Console app. One or more of these console apps are started based on your Worker settings. Since these run as Console apps, the OS treats them as separate processes and spreads them out amongst available CPU cores.

Comments closedOne of the trickier things when dealing with PDF document creation is typography. By default, the PDF typography handling in Xojo’s PDFDocument class includes the “standard 14“, 14 typefaces you can use freely without requiring them to be included as part of the document itself. This guarantees a very important thing: any user can open and view that PDF document as it was created, without the text suffering from typography substitution, style lost, variations in kerning and tracking, etc. The standard 14 include Times, Courier, Helvetica, Symbol and Zapf Dingbats.

Comments closedOn the forum a user asked if there was a way to create a rectangle with only the top left and top right corners being rounded. Xojo’s built-in RoundRectangle control draws with all four corners rounded, so that was not an option.
