Mike Bell b285ad94d8 PicoVector: Faster polygon rendering. 2025-03-28 10:31:01 +00:00
Phil Howard b3d7bd497d Hershey Fonts: ifdef guard hershey features for eventual deprecation. 
Hershey fonts have all but been replaced by PicoVector's "Alright Fonts"
implementation and in many case we need this flash back!

Phil Howard 5c19c6ab6a PicoVector: AF: Support for 16bit point count. 
Somewhere in the conversion from C++ to C we lost support for 16-bit point counts.

Raise the internal point count to 16-bit, and check for a flag in the font.

If the flag is set, treat the point count as 16-bits, otherwise fallback to 8 for back compatibility.

Phil Howard ba767b5217 PicoVector: Initialise pp_transform(). 
For some reason this was unset causing drawing to fail.

Reset it to a known good state in the constructor.

Phil Howard c3680857ba PicoVector: Fix bug in Polygon.rectangle. 
Fix spurious point in top-left corner causing a broken triangular
rectangle when any permutation of corners other than the bottom-left
is rounded.

Phil Howard 8b32174fc9 PicoVector: Avoid MicroPython GC. 
Since we're not using tracked allocation, any memory we don't explicitly
hold a reference to will be assumed unused by MicroPython's GC.

Pass up the pp_nodes and pp_node_counts points (hackily) to fix this.
 2025-03-28 10:31:01 +00:00
Phil Howard 8f87e1c75f PicoVector: Remove * 4 from pp_nodes lookup. 2025-03-28 10:31:01 +00:00

Phil Howard 074570f99c PicoVector: Revert the tile buffer to be fixed. 
Ensure that MicroPython doesn't ever place the tile buffer into PSRAM
and trash performance.

Phil Howard 089e5df243 PicoVector: Refactor text multiline support. 
Drop dependence on null terminated strings, and for a final linebreak.

Bound all text processing using the text length.

* Remove Polygon types in favour of primitives .circle, .rectangle etc
* Add a new Transform type for building up transformation matrices
* Add support to set/clear transform on drawing

Phil Howard 9879e6d602 PicoVector: Fix out of bounds drawing. 
pretty-poly.h is not giving us fully clipped rectangles, so revert to the
slower bounds checked pixel for now.
 2025-03-28 10:31:01 +00:00
Phil Howard 2fc45d0737 PicoVector: fix pointer arithmatic in af_load_font_file. 
Pointers were being incremented as if they were bytes, rather than larger
containers.

Phil Howard e46fec7902 PicoGraphics: Layers. 
Add preliminary support for multiple layered drawing surfaces.

Allows, for example, static content to be loaded into one layer and
remain unmodified while the above layer contains animations.

Particularly useful for drawing PNG or JPEG UI elements which are
then overdrawn with text or animated elements, without paying the
cost of loading/decoding every frame.

Merge pull request #1042 from jaeheonshim-forks/inky-blocking-fix 
Fix: Properly implement non-blocking update functions for the Inky Frame
 2025-01-15 11:33:56 +00:00
Phil Howard 19689b4414 PicoGraphics: Fix overflow bug in p4 pixel span. 
A properly aligned zero length pixel span would cause a single
pixel to be drawn, the length overflowed and a subsequent
2GB of pixels drawn by the main loop.

Add a simple check to discard any attempt to draw zero length spans.
