image

问题 On a custom made product view page i'm working off from there is the base image (the large one) and a list of thumbnails which are other images associated with the product in the media gallery (they are just normal images and not the defined thumbnail), what i've been tasked to to is get it so that when you click on a thumbnail it'll change the base image above i've got that working however i have a problem, when i change the image the image it changes to is very pixelated one, the base image

问题 I'm getting the following error in iOS 11 when scrolling through the page. (In Firefox, Safari and Chrome). In Android devices the error is not happening. These are background images, I don't know if that could be the reason that's causing the error. Image 2 shows how the image is intended and shown in Android. <div className="shelf-page-lists-icons-background" style={containerImage} /> <div style={styles.container} > <p style={styles.listsTitle}>{list.title}</p> </div> CSS containerImage = {

问题 I keep reading that images are already loaded asynchronously, or to use onload (which doesn't solve the problem). When loading a large image, specifically from canvas.toDataURL() , the whole page freezes while the image is being loaded. What I'm doing specifically is prerendering a procedurally generated map (for a game) in a hidden canvas, then loading that data into an image to draw faster. The actual problem is setting the src, which happens even if I just img.src=img.src to invoke loading

问题 Suppose that the corresponding function in views.py looks like from PIL import Image def get_img(request, img_source) base_image = Image.open(os.getcwd() + '/deskprod/media/img/'+ img_source + ".png") #Some editing of base_image done with PIL that prevents image from being directly loaded in html return render_to_response('get_img.html', { 'base_image': base_image}, context_instance=RequestContext(request)) How can I then display base_image in the get_img.html template? 回答1: You should

问题 ArrayList<String> imageFileList = new ArrayList<>(); ArrayList<RecentImagesModel> fileInfo = new ArrayList<>(); File targetDirector = new File(/storage/emulated/0/DCIM/Camera/); if (targetDirector.listFiles() != null) { File[] files = targetDirector.listFiles(); int i = files.length - 1; while (imageFileList.size() < 10) { File file = files[i]; if (file.getAbsoluteFile().toString().trim().endsWith(".jpg")) { imageFileList.add(file.getAbsolutePath()); } else if (file.getAbsoluteFile().toString

问题 I am writing this flutter code where I have Image in an Image widget and I want to convert it into File so that I can upload it to Firebase Storage. Image _image = Image.asset('assets\images\profile.png'); File _fileImage = convertToFile(_image); //upload _fileImage to Firebase Storage code I need the File convertToFile(Image img) function. 回答1: Special thanks to sami kanafani. This is my solution (works perfectly for me): import 'dart:async'; import 'dart:io'; import 'package:flutter

问题 Simply put, what I'm trying to do is similar to this question: Convert RGB image to index image, but instead of 1-channel index image, I want to get n-channel image where img[h, w] is a one-hot encoded vector. For example, if the input image is [[[0, 0, 0], [255, 255, 255]] , and index 0 is assigned to black and 1 is assigned to white, then the desired output is [[[1, 0], [0, 1]]] . Like the previous person asked the question, I have implemented this naively, but the code runs quite slowly,
