slice

Is there any way to slice an SVG . I mean any already available lib . I need to implement this slicing component in Java. I mean , I have single SVG file and based rulers/scales i choose graphically , I want to slice the single SVG into different SVG files. Hope I am clear Yes, although, you'd think this was classified information - or just simply impossible - based on how hard it is to find this basic fact.... Apparently , all you need to do is reference the viewBox from a URI "fragment". . I have confirmed, it does indeed work. Take the following example... The lesson of the story, in case

What happens if I return a slice of an array that is a local variable of a function or method? Does Go copy the array data into a slice create with make() ? Will the capacity match the slice size or the array size? func foo() []uint64 { var tmp [100]uint64 end := 0 ... for ... { ... tmp[end] = uint64(...) end++ ... } ... return tmp[:end] } icza This is detailed in Spec: Slice expressions . The array will not be copied, but instead the result of the slice expression will be a slice that refers to the array. In Go it is perfectly safe to return local variables or their addresses from functions

I've been trying to slice two characters out of a string using a loop, but instead of grabbing two characters, it only grabs one. I've tried: input[i:i+1] and input[i:(i+1)] but neither seems to work. How do I use a variable for slicing? The full routine: def StringTo2ByteList(input): # converts data string to a byte list, written for ascii input only rlist = [] for i in range(0, len(input), 2): rlist.append(input[i:(i+1)]) return rlist The slice values aren't the start and end characters of the slice, they're the start and end points . If you want to slice two elements then your stop must be

I have an array A of boolean values, indexed by integers 0 to n , all initially set to true . My current implementation is : for i := 0; i < n; i++ { A[i] = true } icza Using a for loop is the simplest solution. Creating an array or slice will always return you a zeroed value. Which in case of bool means all values will be false (the zero value of type bool ). Note that using a Composite literal you can create and initialize a slice or array, but that won't be any shorter: b1 := []bool{true, true, true} b2 := [3]bool{true, true, true} If you don't want to use a for loop, you can make it a

1.部分基本类型 　　go中的类型与c的相似，常用类型有一个特例：byte类型，即字节类型，长度为，默认值是0； 1 bytes = [5]btye{'h', 'e', 'l', 'l', 'o'} 　　变量bytes的类型是[5]byte，一个由5个字节组成的数组。它的内存表示就是连起来的5个字节，就像C的数组。 1.1字符串 　　字符串在Go语言内存模型中用一个2字长(64位，32位内存布局方式下)的数据结构表示。它包含一个指向字符串数据存储地方的指针，和一个字符串长度数据如下图： 　　s是一个string类型的字符串，因为string类型不可变，对于多字符串共享同一个存储数据是安全的。切分操作 str[i:j] 会得到一个新的2字长结构t，一个可能不同的但仍指向同一个字节序列(即上文说的存储数据)的指针和长度数据。所以字符串切分不涉及内存分配或复制操作，其效率等同于传递下标。 1.2数组 　　数组类型定义了长度和元素类型。如， [4]int 类型表示一个四个整数的数组，其长度是固定的，长度是数组类型的一部分（ [4]int 和 [5]int 是完全不同的类型）。 数组可以以常规的索引方式访问，表达式 s[n] 访问数组的第 n 个元素。数组不需要显式的初始化；数组的零值是可以直接使用的，数组元素会自动初始化为其对应类型的零值。 1 var a [4]int 2 a[0] =

In the code below I am building data up in a nested list. After the for loop what I would like is to cast it into a multidimensional Numpy array as neatly as possible. However, when I do the array conversion on it, it only seems to convert the outer list into an array. Even worse when I continue downward I wind up with dataPoints as shape (100L,) ...so an array of lists where each list is my data (obviously I wanted a (100,3) ). I have tried fooling with numpy.asanyarray() also but I can't seem to work it out. I would really like a 3d array from my 3d list from the outset if that is possible.
