Description
Hello Stuart,
could it be that there is a little bug in get_pixels? Please test your code with a 2x8 Image. I changed height and width in the for-loop. After that, my results were better.
Best regards,
Christian
def get_pixels(self):
"""
Returns a multi-dimensional array of the RGB values of each pixel in the
image, arranged by rows and columns from the top-left. Access any pixel
by its location, eg:
pixels = BMPReader(filename).get_pixels()
top_left_px = pixels[0][0] # [255, 0, 0]
bottom_right_px = pixels[8][8] # [0, 255, 255]
"""
pixel_grid = []
pixel_data = list(self._pixel_data) # So we're working on a copy
for x in range(self.height):
col = []
for y in range(self.width):
r = pixel_data.pop()
g = pixel_data.pop()
b = pixel_data.pop()
col.append((r, g, b))
col.reverse()
pixel_grid.append(col)
return pixel_grid
