问题 This is my VERY first post so forgive my newness. I'm trying to make a GUI of a dice rolling game (2 x six-sided). Logic of the random rolls is working fine to console. Also in console I see that die number is mapping to correct image file, but I'm having trouble changing tkinter label images to the new corresponding images on every roll beyond the initial startup roll. On startup, it displays both die images correctly, but when I click "roll" button, both images from first roll just

问题 Let's take a look at this chessboard (https://prnt.sc/r8vjth) As you can see, there are two greenish squares (g8 and f6), which indicate the enemy's move. Square g8 is empty and is pretty easy to find by locateOnScreen function. Problems begin when I am trying to find f6 because it returns again the g8's position. For example, in screenshot's position, it finds the g8. First part is correct, and it comes from the h parameter in the code below. But the second g8 is coming from this function,

问题 Im trying to build an Item Template for my list-view and im bound to a list of Entities. The entity I have has a System.Drawing.Image that I'd like to display, but so far I cannot for the life of me figure out how to bind it to the <Image> block. Every example and documentation I can find on the internet pertains to Images accessible via an uri i.e. File on HDD or On Website <DataTemplate x:Key="LogoPreviewItem"> <Border BorderBrush="Black" BorderThickness="1"> <DockPanel Width="150" Height=

问题 I'm occurring some trouble writing a basic webserver in JAVA. It's currently working fine at delivering html or css files. But when it comes to images things are messed up. I assume I'm doing something wrong at reading the image-files and preparing them to be sent. But have a look at the code: public void launch() { while(true) { try { Socket connection = this.server_socket.accept(); ... PrintWriter print_writer = new PrintWriter(connection.getOutputStream()); String response = this.readFile

问题 For some reason, Im using WCF for webAPIs..I have been using WCF for few days now. On the hunt to find the code to upload image to the server I found many answers and solutions like: Could not upload Image to WCF Rest service Uploading image as attachment in RESTful WCF Service Uploading an image using WCF RESTFul service full working example the above (full woking) example is working for me..accept for the part that it accepts only jpeg images. Since im using Postman to hit on the request,

问题 This question already has answers here : Why does Tkinter image not show up if created in a function?

问题 I have a nice URL structure to loop through: https://marco.ccr.buffalo.edu/images?page=0&score=Clear https://marco.ccr.buffalo.edu/images?page=1&score=Clear https://marco.ccr.buffalo.edu/images?page=2&score=Clear ... I want to loop through each of these pages and download the 21 images (JPEG or PNG). I've seen several Beautiful Soap examples, but Im still struggling to get something that will download multiple images and loop through the URLs. I think I can use urllib to loop through each URL

问题 I am currently, learning the working of Seam Carving aka Content Aware Resizing . Seam Carving involves calculation of Energy of Each individual pixel in an image. Where the Energy could be calculated using several methods, one of which being Gradient Magnitude (Image Gradient). I have previously used Sobel Filter/Operator , which involves calculation of gradients in X and Y direction, where the output of the two is used for finding edges. But, I am not quite sure what a Gradient is by

问题 I have an array which corresponds to the positions of pieces on a chessboard, like so: ['em', 'bn', 'em', 'wr', 'em', 'wp', 'em', 'em'] ['br', 'em', 'bp', 'em', 'em', 'bn', 'wn', 'em'] ['em', 'em', 'bp', 'bp', 'bp', 'em', 'wp', 'bp'] ['bp', 'bp', 'em', 'bp', 'wn', 'em', 'wp', 'em'] .... The 'b' and 'w' signify black and white. n: knight r: rook p: pawn b: bishop k: king q: queen I want to know if there exists some utility which can take this array or something similar and generate a picture

问题 I have code below to look for an image of a sku in a specific folder in our server and insert /autosize - but the issue i have is that if I send this spreadsheet to anyone else not on the server, they cannot see images. Can someone help fix this so it inserts the image dynamically? I believe this is what has to be done to place the actual image in the sheet rather than link-back when the sheet is updated/Opened. Or, how can I format this to send out and include images if they are not linked
