2019-09-04Bitpack bools in TileGrid and GroupScott Shawcroft
2019-09-03Add .hidden to TileGrid and GroupScott Shawcroft
This allows for one to preserve ordering within a Group while hiding something temporarily. Fixes #1688
2019-08-22Regular display fixes including refresh tweaksScott Shawcroft
2019-08-05Merge remote-tracking branch 'adafruit/4.1.x' into merge_in_410Scott Shawcroft
2019-07-19Add support for grayscale displays that are < 8 bit depth.Scott Shawcroft
This also improves Palette so it stores the original RGB888 colors. Lastly, it adds I2CDisplay as a display bus to talk over I2C. Particularly useful for the SSD1306. Fixes #1828. Fixes #1956
2019-07-18Track a dirty area for in-memory bitmapsScott Shawcroft
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
2019-06-12Add partial display update support.Scott Shawcroft
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.
2019-05-21Rework the pixel computation to use areasScott Shawcroft
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.
2019-01-31More improvements to Terminal:Scott Shawcroft
* Fix Hallowing. * Fix builds without displayio. * Fix y bounds that appears as untrollable row of pixels. * Add scrolling to TileGrid. * Remove Sprite to save space. TileGrid is a drop in replacement.
