问题 My blur function is behaving oddly. I've recreated the 3x3 bitmap from check50 to get more approximate results from my tests but, for some reason, every right or lower edge pixels are not working properly. While debugging, I've found that, for some reason, my for loops are not behaving properly. I'll show my code and an example below. Code: // Blur image void blur(int height, int width, RGBTRIPLE image[height][width]) { RGBTRIPLE temp[height][width]; // Declares temporary structure to avoid

问题 So I'm following the example given here (which I modified to only blur, no watermark), to make a blurred image in WordPress on upload. The problem is, that if the uploaded file is the exact same size, or smaller, than the set size, then WordPress will not generate an image, and hence no blurred one will be made. I tried using a isst($meta['sizes']['background-image-blurred']['file']) to determine if one was made, and if not then copy() the source file, but then no WordPress "metadata" would

问题 I have a simple CSS related question. How do I obtain the right end blur/fade as shown in the image? 回答1: Two methods Let's make this: 1. Using box-shadow Browser Compatibility: IE 9 + for box-shadow. Place appropriate box-shadow inset in the div The div is given left padding to line it's text up with the white part of the background (the box-sizing: border-box essentially absorbs the padding into the width) Box-shadow example div { background: url(http://lorempixel.com/output/food-q-c-500

问题 I am working on a CS50 problem set in which I need to do a box blur for each pixel of an image. Though my code is a bit redundant, as I had created 8 if statements for special cases of pixels (like edges and corners), it blurs the image as expected, so I'm not really sure how to fix the problem. Here's the error code: :( blur correctly filters middle pixel expected "127 140 149\n", not "145 160 169\n" :( blur correctly filters pixel on edge expected "80 95 105\n", not "90 106 116\n" :) blur

问题 How can I add a blur view to a label? The label is in front of a UIImage and I wanted the background of the label to be blurred, so that the user can read the text better. I get the Blur effect inside the bounds of the label, but the text itself disappears (maybe also gets blurred, idk why). I also tried to add a label programmatically, but I didn't get it working. I'm thankful for any kind of help! let blur = UIBlurEffect(style: .Light) let blurView = UIVisualEffectView(effect: blur)

问题 Is it possible to add blur effect to picture using painting? If so, how can I do this? 回答1: use this : Stack( children: <Widget>[ YourImageWidget(), new BackdropFilter( filter: ImageFilter.blur(sigmaX: 3.0, sigmaY: 3.0), child: new Container( decoration: new BoxDecoration(color: Colors.white.withOpacity(0.0)), ), ), ], ) 来源： https://stackoverflow.com/questions/60217978/how-to-blur-a-specific-position-in-the-picture-using-custompainter-in-flutter

问题 I'm trying to add a blur effect to a transparent Tkinter widget I'm making. I made the widget partially transparent with this line (snippet) self.attributes("-alpha", 0.85) In order to add the effect I desire I need to get the RGB values of each individual pixel in the widget. Seeing as the widget is only partially opaque I can not use the .cget method because it returns it's fill RGB value (the color before it's made partially transparent), not it's actual RGB value). I currently am using
