bitmaptools.boundary_fill() should do background processing #7485
Description
I landed here after having some freeze problems. Just keeping this here for future reference and in case somebody gets to the same point as myself.
When I tried the following modified code, the communication was lost and the editor (MU) and became unresponsive.
I did the same using TIO and Screen command in ubuntu causing disconnection problems. After a while the code will show the expected result, however the communication is lost with the board. This is a little problem, but if people is impatient as I am, the board will get in safe mode very easily :)
import board
import displayio
import bitmaptools
display = board.DISPLAY
bitmap = displayio.Bitmap(display.width, display.height, 3)
palette = displayio.Palette(3)
palette[0] = 0x000000
palette[1] = 0xffffff
palette[2] = 0x0000ff
tile_grid = displayio.TileGrid(bitmap, pixel_shader=palette)
group = displayio.Group()
group.append(tile_grid)
display.show(group)
# Draw a rectangle
for x in range(150, 170):
bitmap[x, 30] = 1
bitmap[x, 50] = 1
for y in range(30, 51):
bitmap[150, y] = 1
bitmap[170, y] = 1
# Draw a non-rectangle
for i in range(30, 120):
bitmap[i, i] = 1
bitmap[i+30, i] = 1
for x in range(0, 30):
bitmap[x+30, 30] = 1
bitmap[x+120, 120] = 1
# fill rectangle white
bitmaptools.boundary_fill(bitmap,display.width//2, display.height//2, 1, 0)
# fill non-rectangle blue
bitmaptools.boundary_fill(bitmap,40, 35, 2, 0)
