rendering

问题 I have two lists: one consists of user added flashcards, which have a question and an answer field (from my Flashcard model). The other consists of words in a song. Then I've made a new list that contains the words where the question overlaps with the lyrics ( user_word in my code below). Now in my html I want to make a table that shows in one column the word from the lyrics, and in the second column the word's meaning, which (if the user has already added the word as a flashcard) will be the

问题 I want to render nested array elements. To render elements I used .map but it is not working for second array. Using list=[{value: 'One', list:[{value: 'abc', selected: false}, {value: 'efg', selected: false}]}, {value: 'Two', list: [{value: 'psr', selected: false}]}]; list.map((item, index) => { return ( <div key={index}> <ul >{item.value}</ul> item.list.map((subitem, i) => { return ( <ul >{subitem.value}</ul> ) }) </div> ) }) Am I missing anything here? Thanks 回答1: Try this. You missed { }

问题 I have a set of anti-aliased greyscale PNG images. I need to know how to programatically revert the anti-aliasing effect and get sharp edges again. I'm using GDI+ but I am less interested in code. I need an algorithm, maybe a convolution filter, if such a matrix can be built. The greyscale images (should) contain only 6 colors (or different shades of grey). This is so that later on I can re-color them using a Color-Lookup filter. However, when the images where saved, Photoshop automatically

问题 I'm using the newest version of Xcode and Swift . I was googling around to make my KWWebView even faster and found the following: webConfiguration.suppressesIncrementalRendering = true Documentation says the following: A Boolean value indicating whether the web view suppresses content rendering until it is fully loaded into memory. But what does this mean? Does it mean, the html doesn't not get rendered and shown as long as not all resources like images and javascript files are completely

问题 I have been doing a small little project using Processing, and the effect I wanted to achieve was a kind of "mountains" forming and moving, using Perlin Noise with the noise() function, with 2 parameters. I was originally using a image for the background, but for illustrational purposes, I made the background black, and it's basically the same effect. My issue is that I want to have a "history" of the mountains because they should fade away after some time, and so I made a history of PShapes,

问题 My issue is because a quad is just two triangles. The texture is not rendered consistently on each triangle, and the texture is broken across the border between the two triangles. I'm using a screenshot of my lovely Minecraft house as an example texture: Rendered textured quad As you see, from the top left of the screenshot and the bottom right, it seem to have been cut or folded or something. It's just distorted. And the distortion I speak of is NOT from the fact that it's being applied to a

问题 I am new to React, so please don't judge strictly. I am rendering my React app on server and want execute code on frontend side.
