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. 2019-05-31T22:50:55+00:00 Scott Shawcroft scott@tannewt.org 2019-05-31T22:50:55+00:00 urn:sha1:5d0791cafbebf6df7692836b60e86bc1238b4d57 It caused the bottom and right edges to be one pixel short. 2019-05-22T22:00:47+00:00 Scott Shawcroft scott@tannewt.org 2019-05-22T22:00:47+00:00 urn:sha1:7a117f52ed81999261fae3d43dfeb572c5e9887e 2019-05-22T00:41:06+00:00 Scott Shawcroft scott@tannewt.org 2019-05-16T23:45:38+00:00 urn: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. 2019-03-27T14:55:50+00:00 Dan Halbert halbert@halwitz.org 2019-03-27T14:55:50+00:00 urn:sha1:374f210771cf62a35ee3e5c8ffac807ce980fe97 2019-03-13T00:18:33+00:00 Scott Shawcroft scott@tannewt.org 2019-03-12T22:56:03+00:00 urn:sha1:224e9b10092c7142857cafb7df712843906401fd This brings it inline with Group. Also fixes #1613 This also includes a number of fixes for where a method is called through a subclass. We now correctly get the native object. Fixes #1567 Lastly, this adds subscript support to TileGrid for changing tile indices. Similar to Bitmap, it accepts ints or 2-tuples. 2019-02-13T23:31:06+00:00 Scott Shawcroft scott@tannewt.org 2019-02-13T08:35:14+00:00 urn:sha1:473bdf48f61998ee9c51aa16c159bbc4df1d15b6 * Fixes safe mode on the SAMD51. The "preserved" value was being clobbered by the bootloader. * Fixes auto-reload loop when in safe mode. * Fixes reading Group children with []. * Check that a TileGrid actually moves before queueing a refresh.
