Phil Howard 638ff3d8f4 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Hershey fonts have all but been replaced by PicoVector's "Alright Fonts"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 1a8f8e9aae PicoGraphics: Support multiple layers in more types. 2025-04-25 17:33:52 +01:00
Phil Howard 354c95ca61 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.

Phil Howard fba7b53c36 PicoGraphics: Fixed-width bitmap font support. 2023-05-15 11:03:39 +01:00
Phil Howard 73f50e43ec Hershey Fonts: Replace map lookup to avoid std::string. 2023-03-16 13:25:19 +00:00
Phil Howard 375df60ff3 PicoGraphics: Switch to string_view. 
MicroPython's GET_STR_DATA_LEN macro returns a const byte array and len, which std::string would copy into heap.

Using string_view lets us wrap the existing const values.

PicoGraphics: HSV Pen (#665) 
Co-authored-by: Gee Bartlett <122281230+ageeandakeyboard@users.noreply.github.com>

jon 63183d28be Lots of features added 2022-10-13 13:19:50 +01:00
Phil Howard fc3060b640 PicoGraphics: Simplify RGB565 frame convert. 
Rewrite RGB565 frame convert to iterate over pixels by index, and transfer the buffer when it fills.

Avoid using a bitmask so BUF_LEN can be arbitrary.
 2022-09-21 11:32:19 +01:00
Mike Bell 7f330d1a04 Pico Graphics: Use fixed size buffer for frame conversion 2022-08-23 23:07:13 +01:00
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
jon 077159adeb PicoGraphics: Add set_pixel_span and call where appropriate. 2022-06-17 11:04:02 +01:00

Phil Howard 5d7113e8c9 PicoGraphics: Basic 128x128 RGB332 spritesheet support. 2022-06-13 20:12:03 +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.

Phil Howard 67f1331b23 ST7789 -> PicoGraphics 
* Absorb ST7735 support into the generic ST7789 driver and rename to PicoGraphics
* Delete obsolete MicroPython modules
* Refactor PicoGraphics to inherited class for each pen type
* Refactor ST7789 and ST7735 to derive from DisplayDriver
* Allow user to set pen_type in MicroPython constructor for RGB565, RGB332, P8 and P4 modes
 2022-06-13 20:11:49 +01:00
Phil Howard 7e4725d1cd ST7789/PicoGraphics: Templated framebuffer formats. 2022-06-13 20:11:09 +01:00
Phil Howard 65788ae6bf ST7789/PicoGraphics: Faster RGB332 mode lookups. 
Replace palette search in RGB332 mode with a simple return of the RGB565 colour packed to RGB332,
since this is identical to its index in the palette.

Phil Howard 3b8dcecd8e Pico Graphics: Move bitmap fonts into generic library. 
* Add bitmap font support into Badger 2040
 2022-03-30 15:10:52 +01:00
Phil Howard 276528c119 Make font settable by user at runtime 
This allows fonts to be hot-swapped out by calling `set_font`

Unfortunately the way fonts are currently stored limits the maximum height to 8 pixels, since that's the size of a uint8_t and the y dimension is bitwise encoded.

The width can be arbitrary, by specifying the widths and max_width (the multiplier for number of bytes per char).

Might be worth grabbing some more bits from 32blit to make this not terrible, but now a user-defined font is an .hpp and a `set_font` away.

David Tillotson 4cecb920bf Adjusted font_data in graphics lib code to enable different height fonts 2021-03-29 13:27:25 +01:00
Phil Howard 675106ece4 Patch or suppress warnings 
The upstream MicroPython rp2 port has re-enabled -Werror so we need to either fix warnings or,
in the case of those generated by C++/C MicroPython binding weirdness, suppress them.
