Phil Howard fd21d61bea PicoVector: Fix find_glyph char to uint16_t. 
Allow find_glyph to find 16-bit unicode codepoints (icons, yay!).
 2025-05-22 16:00:59 +01:00
Phil Howard fba0f1c962 PicoVector: Add tracked memory alloc, track the node buffer. 
With a low GC threshold the node buffer was being collected (despite guards against this)
and causing further drawing operations to be corrupted.

Add a new tracked malloc method and use it for node buffers and font data.

Tweak pp_poly_add_path to accept a point count, avoiding many successive rellocs when
dealing with a known quantity of points (copying from an af_glyph_t.)

ihaanaho 7a894dc512 PicoVector: Add support for utf-8 characters. 2025-04-25 17:43:13 +01:00
Mike Bell d84a1e3470 PicoVector: Faster polygon rendering. 2025-04-25 17:33:53 +01:00
Phil Howard 5e114e97c4 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 27bd5eecde 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 4c55038f94 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.

Jonathan Williamson a0f35a6834 PicoVector: Add star and line primitives. 2025-04-25 17:33:52 +01:00
Phil Howard d2728d4b06 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.
 2025-04-25 17:33:52 +01:00
Phil Howard 78eb6da31b PicoVector: Remove * 4 from pp_nodes lookup. 2025-04-25 17:33:52 +01:00

Phil Howard 8d8b950308 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 b40818c900 PicoVector: Refactor text multiline support. 
Drop dependence on null terminated strings, and for a final linebreak.

Bound all text processing using the text length.

* Add a new Transform type for building up transformation matrices
* Add support to set/clear transform on drawing

Phil Howard 56d430b862 PicoVector: fix pointer arithmatic in af_load_font_file.
