python光栅图像HEX代码

Question

我目前使用ESCPOS命令集使用热敏打印机。

我得到了这张图片：

他们给了我正确的十六进制代码我必须发送到打印机打印上面的图像。上图中的代码：

他们告诉我使用光栅图像＆＃39;生成代码。我找不到任何解决方案，为我返回上面图片的正确代码。

在进入上面显示的图片时，知道如何让函数返回上面的代码吗？

Answer 1

您获得的栅格数据是128行，每行16个字节，前导2个字节设置栅格大小（128 x 128）。每个位是0或1，定义不打印（白色）或打印（例如黑色），例如，一种简单的黑白格式。

看起来这些字节是从上到下编码像素而不是从左到右编码，因为你生成的字节会生成翻转和旋转的图像：

但如果您将数据视为最重要的位是左上方并且跟随位向下而不是向右，则得到：

将图像转换为黑白后，您必须自己从图像中生成相同的数据。根据PIL图像'1'模式图像，逐行读取从上到下的黑白图像数据。如果您转置图像（翻转和旋转），您可以将列放入行中并使用Image.tobytes()在一个步骤中获取所需的字节，并使用1;I模式为原始编码器生成反转数据：

from PIL import Image, ImageOps
img = Image.open("original.png")
bwimg = img.convert('1')
transposed = bwimg.transpose(Image.ROTATE_270).transpose(Image.FLIP_LEFT_RIGHT)
data = bytearray(transposed.size)
data.extend(transposed.tobytes('raw', '1;I'))

一旦你有一个正确方向的黑白图像（模式1），你所要做的就是将大小作为前2个字节，tobytes()方法产生原始图像数据（每像素1位）。

原始编码器的'1;I'模式生成0表示白色，1表示黑色而不是默认0表示黑色，1表示白色模式，请参阅raw modes table。

对于输入图像（与您给出的栅格数据略有不同），产生：
