Python - 将位图图像转换为每个像素的颜色列表

时间:2017-03-24 23:52:34

标签: python python-3.x bitmap

我有一个功能强大的代码,用于22到22像素的位图,但是除了奇怪的事情之外,任何人都知道为什么? 该程序将用于自动化在我的世界中建造大型结构/可能是其他基于像素的'游戏。目前的状态是22比22像素,但不多了,我想知道为什么/如何解决它。

当前错误消息(对于超过22像素的图像):     KeyError(搜索调色板时,原因:颜色不再是rgb的元组,而是一个未知原因的单个数字

所需的大小最多128到128,结果是(对于2乘1位图) - 简化,因为它可能必须是正方形: [(0,0,' 0-0-0',黑色),(0,1,' 255,255,255',白色)]

当前节目:

# palette.py
# Palette with rgb-values depicting different blocks in-game:
predef = {}         #initialize a list variable, the fill it:
predef['255-255-255'] = 'air'
predef['255---0---0'] = 'redstone_block'
predef['--0--38-255'] = 'lapis_block'
predef['0-0-0'] = 'coal_block'

# main.py
from PIL import Image
import numpy as np
import json
import palette

def convert(filein, pal = palette.predef, zz = 0):
    '''
    due to a combined internal/external palette system ignore the warnings about incoherent types of str and dict
    as the dict is the internal, and the str is the filename of a json containing a dict.

    :param filein: Filename of bitmap
    :param pal: blank to use internal, or specify a separate palette.json
    :return:
    '''
    customset = []                  # customset list for blocks and positions

    if pal is not palette.predef:
        with open(pal) as js:
            pal = json.load(js)
        #print(pal) #debug to check palette

    im = Image.open(str(filein))
    p = np.array(im) #.reshape(-1, 3)
    print('width/height:', len(p), 'by', len(p))
    for y in range(0, len(p)):
        for x in range(0, len(p)):
            pix = p[y][x]
            pix = str(pix).replace(' ', '-').replace('[', '').replace(']', '')
            print(pix)
            pixcolor = (y, x, pix, pal[pix])     # Switch comment statu on these to see the error
            #pixcolor = pix                      # instead of the error message

            customset.append(pixcolor)

    return customset

print(convert('./1.bmp', './palettetest.json') # works with a bitmap up to 22 by 22

找到了解决方案:

来自PIL导入图片     导入numpy为np     导入json     进口时间     导入调色板#当我们有-0 --- 0 --- 0时,为什么需要这个? -Unknown
