Phil Howard cd2e412ef4 MicroPython: Add MP_ERROR_TEXT() for mp_raise_msg() calls. 2025-04-25 17:33:53 +01:00
Phil Howard 5ed7913a2c MicroPython: Fix errors reporting an errno. 2025-04-25 17:33:53 +01:00
Phil Howard 5aaf5d3608 MicroPython: Add MP_ERROR_TEXT() around errors. 
This is required for MicroPython error text compression which is
going to be enabled by default for RP2 builds.

We have a lot of error messages, so the potential flash gain here
is worth the effort of making this work.

Phil Howard 1488a0b796 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 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 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 77a5edc83f MicroPython: Update to support new slots mp_obj_type_t. 
Follows the lead from: 662b9761b3

Update to support MP_DEFINE_CONST_OBJ_TYPE with backwards compatibility.
 2023-01-11 09:46:45 +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
 2022-12-14 18:42:03 +00:00
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 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 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 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 6a3ba0d421 MicroPython: Shim MP_REGISTER_MODULE for >1.18 compat. 
MicroPython has changed MP_REGISTER_MODULE to use only *two* args and now runs the preprocessing stage on files before running makemoduledefs.py.

This change avoids the build exploding, since the new regex matches the last two args as a single argument and generates a malformed module defs include.

The pattern here exploits the fact that 1.18 and below do not preprocess files, so *both* MP_REGISTER_MODULE lines are included in the source, but *only* the three arg version is matched by regex.

In >1.18 the files will be processed and the three arg version removed before makemoduledefs.py processes it.

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.
