问题 I am currently trying to make better responsive images on my site. After some research I found the the srcset and sizes attributes. My goal here is the following: When the screen size is above 600px or below 300px I want to serve a 250x250 image When it is between these two values I want to serve a 350x350 image Also I want higher resolution images for screens which have a higher pixel ratio This is what I came up with. But it is not working as I though it would. The small 250x250 is always

问题 I'm creating a few Image objects and when I setup network throttling in Dev Tools I see that onload functions are invoking before my images are fully loaded. I really cannot find the solution. My code: function imgObjects(data) { for (var i in data) { img[data[i].id] = new Image(); img[data[i].id].onload = imgReady(); img[data[i].id].name = data[i].name; img[data[i].id].src = data[i].image; } } function imgReady() { imgReadyCount++; console.log('Count: ', imgReadyCount); } I you happen to

问题 EDIT: Actually, I need a way I can read the lines and extract the pixel info into some structure so I can use the putpixel function to create an image based on the ppm p3 file. I've been trying this for so long and I can't just get it right. I'm working with Python Imaging Library (PIL) and I want to open a PPM image and display it as an image on the screen. How can I do that using only PIL? this is my ppm image. it's just a 7x1 image that i created. P3 # size 7x1 7 1 255 0 0 0 201 24 24 24

问题 I am trying to programmatically set the width and heights of the chained bodies in matter.js. Unfortunately, I am only getting 0 as values and I am unsure why. My guess is that the images are not being loaded fast enough to provide those values. How can I load those dimensions before the images are loaded? Pseudo-code Several bodies from Array Get the width and height of each image in the Array Use this value to set the Bodies dimensions Code var playA = Composites.stack( percentX(25) -

问题 I'm trying to figure out how to get text to flow around an irregular shape on a page, and am not having much luck figuring out how to do what I am trying to do. I attached an image showing the layout the I am trying to use. I want the text to flow the way it does in the image. I did this mock-up in MS Paint. Each page could have any content on it, so I'd rather not have to manually adjust the text on each page. The top-left corner will always be the same, so ideally there would be a CSS rule
