问题 The code that I have used for creating PDF s given below and my requirement is to make the PDF content not select (it should be like a Image) , that I have achieved.

问题 When I put an img tag inside a inline-block element and give padding to it the parent isn't growing as it should. article { background: fuchsia; display: inline-block; } img { padding: 5%; } <article> <img src="https://fakeimg.pl/412x412"/> </article> CodePen: https://codepen.io/Yarmolaev/pen/xxxbeJr 回答1: It's the use of percentage value that consider the parent width as reference. Here you have a kind of cycle since the width is also based on the content. In this case the browser is ignoring

问题 My array is of type [[Int]] array = [[1,2,3], [4,5,6], [7,8,9,10], [11,12,13], [14,15,16]] I want the transpose result as: array = [[1,4,7,11,14], [2,5,8,12,15], [3,6,9,13,16], [0,0,10,0,0]] How to pad 0's to an array which does not have an equal row or column mapping. I want the transpose to work for both rows and columns with unequal mapping elements. Please help. 回答1: Here is an implementation that does what you want: func transpose(_ input: [[Int]]) -> [[Int]] { let columns = input.count

问题 I was looking at some examples of lists when noticed one example which I couldn't explain. This is website I was looking at http://css.maxdesign.com.au/listamatic/horizontal05.htm and this is code from it: <div id="navcontainer"> <ul id="navlist"> <li id="active"><a href="#" id="current">Item one</a></li> <li><a href="#">Item two</a></li> <li><a href="#">Item three</a></li> <li><a href="#">Item four</a></li> <li><a href="#">Item five</a></li> </ul> </div> #navlist { padding: 3px 0; margin

问题 I want to use python to encrypt some data and have come across pycrypto as a possible tool. In order to encrypt the data, I need to: Input passphrase string SHA-256 the string, giving key for AES-256 Represent sensitive data as string of 9 digit characters (ascii), with leading ascii 0s if present (the data will always be in this format). Encrypt data string using AES-256, NO SALT, using PKCS7 padding from RFC2315, in ecb mode. Represent ciphertext as Base64 (RFC 4648), needing 24 characters

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 2 years ago . Improve this question What is the different between RSA-OAEP and RSA-PKCS1.5? My understanding is they are both RSA encryption, but using different padding schemes. What is the advantage of one over the other? If I generate a RSA 2048 pirate and public key pair, can I use the same
