问题 My website hosts a lot of images of all sizes. These images are responsive and change size at all browser widths from desktop to mobile. I see in my Google Search Console that I have a poor CLS (cumulative layout shift) of .25s. The layout of my website shifts as the images load. Since my images are responsive, I can't specify exact sizes of the images, or have placeholders to reserve the space. What is a modern way to prevent CLS with responsive images?

问题 I am customizing woocommerce themes. I stuck on loop product using hook action woocommerce. To call/include the thumbnail image in a loop, we call this hook <?php do_action('woocommerce_before_shop_loop_item_title'); ?> And the thumbnail image appears. I am confused where is the <img src"" .... location? How to edit that code?

问题 I have a picture were I want to change all white-ish pixels to grey, but only for a certain area of the image. Example picture, I just want to change the picture outside of the red rectangle, without changing the image within the red rectangle: I already have the general code, which was part of someone elses Stackoverflow question, that changes the colour of every white pixel instead of only just the one outside of an area. image = cv.imread("meme 2.jpg") hsv = cv.cvtColor(image, cv.COLOR

问题 Supposed I have a single page application that uses JWT tokens to authenticate against a backend REST api. I transfer the JWT token inside the http header when doing a REST request. So far, so good. Now, supposed I want to download an image from the server, and I want the image only to be accessible for authenticated users. On the server, this is no problem: Simply define a route that delivers the image, and in that route verify the JWT token. But: How do I transfer the token from the client

问题 I am trying to read and write jpegs wth Adobe RGB colorspace in OpenCV. OpenCV assumes the jpeg has sRGB colorspace and when displaying or writing to file, the image loses some of its color intensity. I found this intensity loss was due to colorspace difference by answers given to my previous question. Is there anyway I can make OpenCV to read Adobe RGB colorspace without casting it to sRGB? 回答1: Some information that is hopefully useful for anyone looking for a work-around for dealing with

问题 This is one of those "pretty sure we found the answer, but hoping we're wrong" questions. We are looking at a steganography problem and it's not pretty. Situation: We have a series of images. We want to mark them (watermark) so the watermarks survive a series of conditions. The kicker is, we are using a lossfull format, JPG, rather than lossless such as PNG. Our watermarks need to survive screenshotting and, furthermore, need to be invisible to the naked eye. Finally, they need contain at
