From exciting educational sessions, to an exploration of the Xojo product roadmap, to informative presentations from Xojo Engineers about how Xojo is made and the Xojo framework, there was a lot to take in! If you missed any of the announcements that were shared, you can watch Founder and CEO Geoff Perlman’s Conference Keynote free on YouTube. The rest of the session videos are available for purchase here.
Comments closedXojo has very good graphics support. You can drop images into your project and use them with several controls. You can use the various Paint events to draw your own graphics.

Comments closedI was recently asked if there was a way to use Xojo Canvas Graphics to draw using the math X-Y coordinate system. First a little background. In Xojo (along with Java, .NET and many other languages), graphics are drawn where (0,0) is at the top left, X increases to the right and Y increases down. Other languages or APIs (Cocoa, for example) use a system where (0,0) is at the bottom left, X increases to the right and Y increases up.

Continue reading and I will show you how to create a Method Extension for the Picture class that will be able to do that. This will work on Desktop and iOS projects by only copying and pasting the code, but you will need to make some changes to the example project for the Web version because of the need to convert Picture to WebPicture and back.
