Phil Howard 7fee95d668 PNG/JPEGDEC: Remove finalizer. 
Remove the finalizer from PNGDEC and JPEGDEC, since it was both redundant
and actively harmful.

The finalizer was just calling "close" which is unecessary since the file
is closed automatically after opening/rendering and not left open.

If a file did not exist and "open_file" bailed with ENOENT then it would
be left in an unknown state, and the finalizer calling "close" would
cause a hardlock.

Phil Howard 25627588c3 PNG/JPEGDEC: Use MP_ROM_QSTR. 2025-03-28 10:31:01 +00:00
Phil Howard 517f8ae1cd global: Remove the STATIC macro. 
Reflect the changes proposed in micropython/micropython#13763.

Phil Howard 47e3aed88f MicroPython: Switch to mp_obj_malloc_with_finaliser. 2024-06-03 11:40:29 +01:00
Skyler Mansfield b23a71b889 JPEGDEC: Backport width/height changes from pngdec. 
Open JPEG file or stream to read width/height before decode.

Phil Howard d45daef654 MicroPython: Switch from MICROPY_EVENT_POLL_HOOK to mp_event_handle_nowait(). 
Note: Unsure if mp_event_handle_nowait() is the right answer in all cases,
but this seems to be what we want in our blocking loops.

Phil Howard 4b3e83f2ff JPEGDEC: Treat byte arrays as raw JPEG data for #435. 2023-09-29 09:18:55 +01:00

Phil Howard b74b371d2b JPEGDEC: Don't pass filename through std::string. 
The result of GET_STR_DATA_LEN should be null terminated, so converting to a std::string and then using .c_str() is both redundant and need
s heap.

Phil Howard bea90dfd60 JPEGDEC: Experimental 3bit/4bit palette no-dither. 2023-02-22 15:40:22 +00:00
Phil Howard 4928ceff8d Inky 7.3: Add pen type to JPEGDEC. 2023-02-20 12:29:59 +00:00
Phil Howard 9bd29e0ef2 JPEGDEC: Fix iWidthUsed skip not advancing pixel pointer. 2023-02-10 22:12:02 +00:00
Phil Howard 13414b5037 JPEGDEC: Clip drawing to iWidthUsed. 
Corrects clipping width using new iWidthUsed value, noticable particularly on smaller jpegs and those that aren't a multiple of the MCU sized.

Fixes #573

Phil Howard 241e725464 JPEGDEC: Sync with upstream. 
Adds setUserPointer and pDraw->pUser which we now use to store a pointer to the PicoGraphics instance.

Phil Howard fddac54f86 JPEGDEC: Add option to disable dither on RGB332. 2022-08-11 11:46:45 +01:00
jon 50c7bd69ee Added missing switch case for new RGB888 pen type 2022-07-26 05:34:23 +01:00
Phil Howard 6c1556a429 PicoGraphics: 1bit/1bitY dither all drawing operations. 
Note: Pen now ranges from 0 (black) to 15 (white). Values between will be dithered ala Badger 2040.

Phil Howard 12866a0b7b PicoGraphics/JPEGDEC: Use PicoGraphics dither. 2022-07-06 10:56:56 +01:00
Phil Howard cb5f8308a0 PicoGraphics/UC8159: 3bit bitplane pen mode. 
Add a 3bit pen mode to save 1/4th the RAM needed for the 600x448 Inky Frame.
 2022-06-30 15:25:02 +01:00
Phil Howard 7dbec2add6 JPEGDEC: Stream from filesystem. 
Avoid loading jpeg files into RAM and stream from the filesystem to handle larger files gracefully.
 2022-06-24 11:03:29 +01:00
Phil Howard e3f98d56cf PicoGraphics: UC8151 Support for Inky Pack. 2022-06-23 15:48:45 +01:00
jon 360bf4310c SH1107: Add driver and example. 
Add 1bit pen mode to PicoGraphics.

TODO:

* Rotation support
* Sizes other than 128x128 support

Phil Howard 31ade6af72 JPEGDEC: Open just before decode to avoid seek overrun. 2022-06-14 15:38:25 +01:00
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.
