TPL_KUNENA_MESSAGE_CREATED Drawing rotated strings in a lua app tele window
08 Feb 2023 23:12 - 08 Feb 2023 23:13
Hi all,
For a project I am working on now, I needed to draw some rotated character strings .. in my case only numbers. I looked around for some good single line fonts and found an interesting website that had a nice simple font. It's an old-school-looking font. Links are in the app source file.
I was a little concerned about CPU usage, and it turns out if you draw it with the anti-alias rendering API it consumes about 2% of CPU per character drawn, which is manageable in my case.
You can find the code and a test app on my github page: github.com/davidmcq137/JetiLuaDFM/blob/0.../misclua/hp1345a.lua
I hope this is of some use to other lua app developers.
Dave

Sometimes when we are coding, we laugh out loud at dumb things we do (well, at least I do!)
First time I went to use this I realized I forgot to include the minus sign, so I could not do negative numbers...
Here is an update: github.com/davidmcq137/JetiLuaDFM/blob/1.../misclua/hp1345a.lua
The project I am working on is an instrument panel generator with a number of different gauges and widgets that are drawn with a drag and drop interface on a website .. then downloaded with a companion lua app to the TX. It uses the same pilot-specific data download idea as my maps app.
Here is the example panel that was driving this "characters on an angle" work. Soon I will be asking if anyone is interested in beta testing.
