How to draw a rounded rectangle?

[SKILA]

Hello all,

Is there a way to draw a rounded filled rectangle dynamically and assign it to a button?

Thanks!

Can i ask why you'd want to do that dynamically? Because the size of your buttons change dynamically? Otherwise i'd simply draw them in paint.exe as an asset and use those. There's no direct support for drawing filled, rounded rectangles, no. You could create a custom widget that took a width and height and color, then you would have 4 images of rounded edges with full alpha that you place in each corner to indicate a rounded rectangle. You'd use the DMA to draw a color for the body and only a small piece of flash for the 4 images, which are reusable for all colors and perhaps sizes.

Perhaps I shouldn't have said dynamic​ because none of the shapes change during runtime. What I would really want to do is reduce the overall size of my firmware. I have many rounded rectangles in my design with a single filled colour. I can see that for some of the large rectangles the size of the generated file exceeds 1Mb which I just feel to be a waste.

Ok. Did my suggestion make sense? You save some flash, pay some RAM instead.
