decode

I receive encoded PDF files regularly. The encoding works like this: the PDFs can be displayed correctly in Acrobat Reader select all and copy the test via Acrobat Reader and paste in a text editor will show that the content are encoded so, examples are: 13579 -> 3579; hello -> jgnnq it's basically an offset (maybe swap) of ASCII characters. The question is how can I find the offset automatically when I have access to only a few samples. I cannot be sure whether the encoding offset is changed. All I know is some text will usually (if not always) show up, e.g. "Name:", "Summary:", "Total:",

How do i decode/open raw image files like .CR2 or .NEF and .ARW without having the codec installed, something like lightroom open raw files ? My code look like this: if (fe == "CR2" | fe == "NEF" | fe == "ARW" ) { BitmapDecoder bmpDec = BitmapDecoder.Create(new Uri(op.FileName), BitmapCreateOptions.DelayCreation, BitmapCacheOption.None); BitmapSource bsource = bmpDec.Frames[0]; info_box.Content = fe; imgControl.Source = bsource; } This work only with the raw codecs installed and dont work with ARW format. If you don't have a codec installed, then you'll have to read the raw image data and

I have done some research and seen solutions but none have worked for me. Python - 'ascii' codec can't decode byte This didn't work for me. And I know the 0xe9 is the é character. But I still can't figure out how to get this working, here is my code output_lines = ['<menu>', '<day name="monday">', '<meal name="BREAKFAST">', '<counter name="Entreé">', '<dish>', '<name icon1="Vegan" icon2="Mindful Item">', 'Cream of Wheat (Farina)','</name>', '</dish>', '</counter >', '</meal >', '</day >', '</menu >'] output_string = '\n'.join([line.encode("utf-8") for line in output_lines]) And this give me

I am having a problem parsing 'jsonp' request with php's json_decode function. My questions is a. What is the use of call back function in 'jsonp', should i just trip that off, or am I suppose to use it in some manner. ? b. How can I rectify the syntax error received in 'jsonp' format ? Below I have given the code and the response that I get. 1. I request a sample url with PHP's curl $url = 'https://ssl.domain.com/data/4564/d.jsonp'; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5); curl_setopt($ch,

from ..box_utils import decode, nms This line is giving error ImportError: attempted relative import with no known parent package What is this error and how to resolve this error? Apparently, box_utils.py isn't part of a package. You still can import functions defined in this file, but only if the python script that tries to import these functions lives in the same directory as box_utils.py , see this answer . Nota bene: In my case, I stumbled upon this error with an import statement with one period, like this: from .generate_holidays import generate_holidays . This syntax, however, tells

　　今天敲代码的时候，遇到一个问题，SQL被除数为0，该怎么办呢？搜来搜去，搜来搜去，最终被机智的我发现了解决问题的方法， 那就是 那就是 那就是 DECODE 当 ！当 ！当 ！ DECODE(SUM( 字段 ), 0, 0,SUM( 参数) / SUM( 参数))那么？ DECODE 该怎么用呢？ 来源： https://www.cnblogs.com/WS97216/p/11693809.html
