For instance, now fill_region uses area routines to order and constrain its coordinates. Happily, this change also frees a modest amount of code space. run code formatting script 2021-03-15T13:57:36+00:00 microDev 70126934+microDev1@users.noreply.github.com 2021-03-15T13:57:36+00:00 urn:sha1:a52eb88031620a81521b937f2a0651dbac2bb350 add fill_region and draw_line to bitmaptools 2021-03-10T17:37:27+00:00 Kevin Matocha kmatocha@icloud.com 2021-03-10T17:37:27+00:00 urn:sha1:85f0f07d51343bd67c1b2308bdfed192cc470549 Track a dirty area for in-memory bitmaps 2019-07-18T23:47:28+00:00 Scott Shawcroft scott@tannewt.org 2019-07-18T23:47:28+00:00 urn:sha1:4a6bdb6fe471b3024b2ca1d977ef02bfd94cc12a This fixes the bug that bitmap changes do not cause screen updates and optimizes the refresh when the bitmap is simply shown on the screen. If the bitmap is used in tiles, then changing it will cause all TileGrids using it to do a full refresh. Fixes #1981 Support multi-byte values with Bitmap 2019-04-04T19:50:35+00:00 Scott Shawcroft scott@tannewt.org 2019-04-04T19:50:35+00:00 urn:sha1:6fcda1dec40efe3513cc5775205d276ea50b4d21 It also corrects the behavior of single byte values. Fixes #1744 A variety of displayio improvements 2019-02-12T04:55:05+00:00 Scott Shawcroft scott@tannewt.org 2019-02-06T20:13:17+00:00 urn: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 Introduce displayio to render graphics to displays. 2018-08-31T19:31:52+00:00 Scott Shawcroft scott@tannewt.org 2018-08-15T18:01:01+00:00 urn:sha1:6697544cdf87d0df5b761d401ad6ffe3a8d752fc It's designed to minimize RAM footprint by using Sprites to represent objects on the screen. The object model also facilitates partial screen updating which reduces the bandwidth needed to display. This is all handled in C. Python simply manipulates the objects with the ability to synchronize to frame timing.
