Among the major enhancements made to the images support in PDFDocument in Xojo 2021r3 release, in addition to transparency support, alpha channel support, and the new way the data is codified in the resulting PDF stream (no more DCTEncoding), we’ve also tackled an issue with images not being as sharp as they should have been.

The PDF Template is not a new feature, but it received a shine in Xojo 2021r3. What’s a PDFDocument template or why would you use them? Let’s look at a couple of scenarios where them are useful including storage, saving time and visual PDF editors.
Comments closedSince its first appearance in Xojo 2020r1, one of the most demanded features for PDFDocument has been the ability to add Table Of Content entries. With Xojo 2021r3 that’s now possible, and pretty straightforward! Continue reading and I will show you how.

Comments closedEarlier this year ago I wrote a post about using the SF Font symbols on macOS Picture.SystemImagein iOS apps. However that technique has some downsides. For one, the symbol glyphs are hardcoded, which means that it’s not possible to access the new symbols added to the SF Font by Apple. In addition, it isn’t possible to set the font weight and scale for the glyph. In this new post, I’ll show a more flexible way to work with these symbols on macOS 11+.
Like many Xojo developers, I often use virtual machines for testing. Over time the virtual machine disk files can get pretty large, even if you…
Comments closedYuck! It happens to everyone, from beginners to experienced developers: sometimes you’ll get stuck. Perhaps the code you’re working on just won’t do what you want or maybe you’re having trouble understanding code plucked from the internet. Talk to the duck. The rubber duck, that is. The term “rubber ducking” or “rubber duck debugging” is a software development technique where you explain the problem you are having to a rubber duck (or appropriate substitute). Often the act of explaining the problem to someone else, even if that someone is not real, can help you figure it out. It might be like inspiration struck.
Comments closedI recently watched this video from Computerphile on YouTube (one of my favorite channels). It demonstrates a simple bit-shift operation can generate amazing random strings of numbers. I thought I’d quickly convert it to Xojo.
Comments closedIn Xojo 2021R2 binary enumerations were introduced. These Enums must be declared in a module and are treated by the compiler as a class. Learn to create an Enum for Days of the Week and demonstrate the use of that by creating a custom segmented button control.
