Over the past few months (off and on), TIny and I have been working on a 16-bits per pixel graphics library for the CE C toolchain. The library uses column-major mode to avoid screen tearing, and allows for logical frames by enabling / disabling framebuffer copies. This is particularly useful given the lack of a buffer when in 16-bpp graphics modes. Here's a list of some of the currently finished routines:

• Set/GetPixel
  
• Rectangles (filled, outline, clipping)
  
• Lines (horizontal, vertical, regular, clipping)
  
• Circles (filled, outline, clipping)
  
• Sprites (transparent, scaled, regular, clipping)
  
• Text (colors, scaling)
  
• A few other things (here's a full list)
  

Here's some eye candy as well:

Feel free to drop any suggestions for routines we should consider including in the library before release 🙂

Also thanks to calc84maniac for giving us some guidance when working with display modes!

Nice work guys, this is awesome 😁

Nice work 🙂

Also a whole bunch of screenshots and not one showing 16bpp graphics ☹️

Interesting, good job!

Here's some fun color gradients (generated using the algorithm from Michael2_3B's color gradient generator):

This looks very promising. The gradients look great, I'm definitely not used to that sort of color fidelity coming from a CE screen haha.

Is this fast enough to be used for games and other real-time applications, particularly relatively complicated ones such as Oiram? Are you aware of a specific consistent point in which it noticeably begins to struggle? Seeing as this is all programmed in assembly, I assume it's reasonably well-optimized enough for most typical use cases.

Definitely going to try my hand at making a Processing-like tool using this. A live code sketch editor for the CE seems like a fun idea to try.

Oof data sizes lol!

But seriously this is great work, HQ visuals calc speaking for sure 😁.

Maybe something like Myst would be a good use of this? (Though you might need the help of a USB drive).

We've added a few things for TLM's picture viewer:
- gfx16_AllocSprite
- gfx16_ScaleSprite
- gfx16_CopyRectangle
