flatten

I'm currently developing a simple photoshop like application on iphone. When I want to flatten my layers, the labels are at the good position but with a bad font size. Here's my code to flatten : UIGraphicsBeginImageContext(CGSizeMake(widthDocument,widthDocument)); for (UILabel *label in arrayLabel) { [label drawTextInRect:label.frame]; } UIImage *image = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); Anybody can help me ? DJPlayer From: pulling an UIImage from a UITextView or UILabel gives white image . // iOS - (UIImage *)grabImage { // Create a "canvas" (image

I have the following element of a list, and the list is 100 elements long. [(50, (2.7387451803816479e-13, 219))] How do I convert each element to look like this? [(50, 2.7387451803816479e-13, 219)] user2357112 [(a, b, c) for a, (b, c) in l] Tuple packing and unpacking solves the problem. New in Python 3.5 with the additional tuple unpacking introduced in PEP 448 , you can use starred expressions in tuple literals such that you can use >>> l = [(50, (2.7387451803816479e-13, 219)), (40, (3.4587451803816479e-13, 220))] >>> [(a, *rest) for a, rest in l] [(50, 2.738745180381648e-13, 219), (40, 3

I need to transform large XML files that have a nested (hierarchical) structure of the form <Root> Flat XML Hierarchical XML (multiple blocks, some repetitive) Flat XML </Root> into a flatter ("shredded") form, with 1 block for each repetitive nested block. The data has numerous different tags and hierarchy variations (especially in the number of tags of the shredded XML before and after the hierarchical XML), so ideally no assumption should be made about tag and attribute names, or the hierarchical level. A top-level view of the hierarchy for just 4 levels would look something like <Level 1>

What is selectMany.ToArray() method? Is it a built in method in C# ? I need to convert two dimensional array to one dimensional array. Marc Gravell If you mean a jagged array ( T[][] ), SelectMany is your friend. If, however, you mean a rectangular array ( T[,] ), then you can just enumerate the date data via foreach - or: int[,] from = new int[,] {{1,2},{3,4},{5,6}}; int[] to = from.Cast<int>().ToArray(); SelectMany is a projection operator, an extension method provided by the namespace System.Linq. It performs a one to many element projection over a sequence, allowing you to "flatten" the

I have an array which contains several arrays, each containing several objects, similar to this. [[object1, object2],[object1],[object1,object2,object3]] Here is a screenhot of the object logged to the console. What would be the best approach to flattening this out so it just an array of objects? I've tried this with no luck: console.log(searchData); var m = [].concat.apply([],searchData); console.log(m); searchData logs out the screenshot above, but m logs out [ ] Here is the actual contents of searchData: [[{"_id":"55064111d06b96d974937a6f","title":"Generic Title","shortname":"generic-title"

I am trying to flatten 3D array into 1D array for "chunk" system in my game. It's a 3D-block game and basically I want the chunk system to be almost identical to Minecraft's system (however, this isn't Minecraft clone by any measure). In my previous 2D-games I have accessed the flattened array with following algorithm: Tiles[x + y * WIDTH] However, this obviously doesn't work with 3D since it's missing the Z-axis. I have no idea how to implement this sort of algorithm in 3D-space. Width, height and depth are all constants (and width is just as large as height). Is it just x + y*WIDTH + Z*DEPTH
