Phil Howard	27d571b473	PicoGraphics: Tidy up dithering.	2022-06-14 15:06:44 +01:00
Phil Howard	2419f0ef45	PicoGraphics/JPEGDEC: RGB332 per channel fast dither.	2022-06-13 20:12:03 +01:00
Phil Howard	602d1b41dd	PicoGraphics: Attempt at dither and scanline interrupts. Currently both unused and both very slow. Dither may only be feasible for <=8 colour displays. JPEGDEC will dither to 4-bit greyscale quite happily.	2022-06-13 20:12:03 +01:00
Phil Howard	656d69399a	JPEGDEC: Fix dither buffer size	2022-06-13 20:12:03 +01:00
Phil Howard	d2b065d2da	JPEGDEC: Use 4-bit dither.	2022-06-13 20:12:03 +01:00
Phil Howard	8917505175	JPEGDEC: Add open_file.	2022-06-13 20:12:03 +01:00
Phil Howard	7f0fe44881	JPEGDEC: Move to libraries, use C++, draw into PicoGraphics.	2022-06-13 20:12:03 +01:00
