Different operations to the display tree have different costs. Be
aware of these costs when optimizing your code.
* Changing tiles indices in a TileGrid will update an area
covering them all.
* Changing a palette will refresh every object that references it.
* Moving a TileGrid will update both where it was and where it moved to.
* Adding something to a Group will refresh each individual area it
covers.
* Removing things from a Group will refresh one area that covers all
previous locations. (Not separate areas like add.)
* Setting a new top level Group will refresh the entire display.
Only TileGrid moves are optimized for overlap. All other overlaps
cause sending of duplicate pixels.
This also adds flip_x, flip_y and transpose_xy to TileGrid. They
change the direction of the pixels but not the location.
Fixes #1169. Fixes #1705. Fixes #1923.
Rework the pixel computation to use areas2019-05-22T00:41:06+00:00Scott Shawcroftscott@tannewt.org2019-05-16T23:45:38+00:00urn:sha1:3fad7de8db7f1f317ab6d00a00a82e406ec6fb33
This changes the displayio pixel computation from per-pixel to
per-area. This is precursor work to updating portions of the screen
(#1169). It should provide mild speedups because bounds checks are
done once per area rather than once per pixel. Filling by area also
allows TileGrid to maintain a row-associative fill pattern even when
the display's refresh is orthogonal to it.
Support multi-byte values with Bitmap2019-04-04T19:50:35+00:00Scott Shawcroftscott@tannewt.org2019-04-04T19:50:35+00:00urn:sha1:6fcda1dec40efe3513cc5775205d276ea50b4d21
It also corrects the behavior of single byte values.
Fixes #1744
Move Glyph and BuiltinFont into fontio2019-03-19T23:22:09+00:00Scott Shawcroftscott@tannewt.org2019-03-19T23:22:09+00:00urn:sha1:5e2fec714cfbff8692d8af4ec8f774738b822ce1
It was confusing in displayio.
Fixes #1662
A variety of displayio improvements2019-02-12T04:55:05+00:00Scott Shawcroftscott@tannewt.org2019-02-06T20:13:17+00:00urn:sha1:c17f147be95e7490e5207c747add2da1cc8b167f
This changes a number of things in displayio:
* Introduces BuiltinFont and Glyph so the built in font can be used by libraries. For boards with
a font it is available as board.TERMINAL_FONT. Fixes #1172
* Remove _load_row from Bitmap in favor of bitmap[] access. Index can be x/y tuple or overall index. Fixes #1191
* Add width and height properties to Bitmap.
* Add insert and [] access to Group. Fixes #1518
* Add index param to pop on Group.
* Terminal no longer takes unicode character info. It takes a BuiltinFont instead.
* Fix Terminal's handling of [###D vt100 commands used when up arrowing into repl history.
* Add x and y positions to Group plus scale as well.
* Add bitmap accessor for BuiltinFont
