将单图位图转换为8位整数的1D C数组

Question

为了澄清标题，我需要将其转换

"00011111111111110000111111111111
00101111111111110000111111111111

每个8x8二进制块的二进制块，以所示格式转换为C数组。在我运行的实际数据中，位图尺寸为128、48，（宽度，高度），因此您不能假设位图高8个。 （否则我不会问这个，这是很重要的）

这是我当前的代码：

# input_str is a (very long) string of binary representation of a bitmap of height 48, width 128.
# I have removed it here as it is irrelevant other than its dimensions.

# I am aware that this code is a mess, but this is just a quick script that I'm only using to 
# automate this task once, as I would rather not sit at my desk for 6 hours sorting out 8x8 blocks 
# of binary from a very long string.

input_str = ""
pass_0 = ""
output_str = ""

IMG_WIDTH = 128
IMG_HEIGHT = 48

BLOCK_SIZE = 8

# Split the bitmap into lines on each 128th index
for i in range(len(input_str)):
    pass_0 += input_str[i]
    if (i % IMG_WIDTH == 0):
        pass_0 += "\n"

# Interate through the lines and get an X block index and a Y block index

blockIndexX = 0
blockIndexY = 0

y = 0
for line in iter(pass_0.splitlines()):
    if (y % BLOCK_SIZE == 0):
        blockIndexY += 1
        
    for x in range(len(line)):
        if (x % BLOCK_SIZE == 0):
            blockIndexX += 1

            blockIndex = (blockIndexX * 6) + blockIndexY

            # And I have no idea how to continue here. 
                
    
    y += 1
    blockIndexX = 0
    

print(output_str)

我设法弄清楚了一种（非常骇人听闻的）方式，那就是将我的输入位图重新格式化为8x768图像，“伸出” 8x8块，使其（某种程度上）琐碎地将其解析到8x8块中。以这种格式，这种（非常Janky and Hacky）代码有效：

# Data omitted for readability reasons

line0 = ""
line1 = ""
line2 = ""
line3 = ""
line4 = ""
line5 = ""
line6 = ""
line7 = ""

blocks = []

for i in range(96):
    blocks.append([])

for i in range(len(line0)):
    character = line0[i]

    if (i % 8 == 0):
        blockIndex = round(i / 8)

        lineSplit = []
        for i in range(0, len(line0), 8):
            lineSplit.append(line0[i : i + 8])


        blocks[blockIndex].append("0b" + lineSplit[blockIndex] + ",")

for i in range(len(line1)):
    character = line1[i]

    if (i % 8 == 0):
        blockIndex = round(i / 8)

        lineSplit = []
        for i in range(0, len(line1), 8):
            lineSplit.append(line1[i : i + 8])


        blocks[blockIndex].append("0b" + lineSplit[blockIndex] + ",")

for i in range(len(line2)):
    character = line2[i]

    if (i % 8 == 0):
        blockIndex = round(i / 8)

        lineSplit = []
        for i in range(0, len(line2), 8):
            lineSplit.append(line2[i : i + 8])


        blocks[blockIndex].append("0b" + lineSplit[blockIndex] + ",")

for i in range(len(line3)):
    character = line3[i]

    if (i % 8 == 0):
        blockIndex = round(i / 8)

        lineSplit = []
        for i in range(0, len(line3), 8):
            lineSplit.append(line3[i : i + 8])


        blocks[blockIndex].append("0b" + lineSplit[blockIndex] + ",")

for i in range(len(line4)):
    character = line4[i]

    if (i % 8 == 0):
        blockIndex = round(i / 8)

        lineSplit = []
        for i in range(0, len(line4), 8):
            lineSplit.append(line4[i : i + 8])


        blocks[blockIndex].append("0b" + lineSplit[blockIndex] + ",")

for i in range(len(line5)):
    character = line5[i]

    if (i % 8 == 0):
        blockIndex = round(i / 8)

        lineSplit = []
        for i in range(0, len(line5), 8):
            lineSplit.append(line5[i : i + 8])


        blocks[blockIndex].append("0b" + lineSplit[blockIndex] + ",")

for i in range(len(line6)):
    character = line6[i]

    if (i % 8 == 0):
        blockIndex = round(i / 8)

        lineSplit = []
        for i in range(0, len(line6), 8):
            lineSplit.append(line6[i : i + 8])


        blocks[blockIndex].append("0b" + lineSplit[blockIndex] + ",")

for i in range(len(line7)):
    character = line7[i]

    if (i % 8 == 0):
        blockIndex = round(i / 8)

        lineSplit = []
        for i in range(0, len(line7), 8):
            lineSplit.append(line7[i : i + 8])


        blocks[blockIndex].append("0b" + lineSplit[blockIndex] + ",")


for k in range(len(blocks)):
    for i in range(len(blocks[k])):
        if (i == 0):
            print(blocks[k][i])
        else:
            print(blocks[k][i])

现在，我觉得我应该这么说：如果您是一个遇到这个人试图做我同样的事情的人，请不要使用这一点代码。只需使用一个用于循环和列表，而不是这种笨拙的黑客入侵。
