I found a solution now, that works, at least if my resulting image is also a JPEG: First I read the image (from byte array imageData), and most important, I also read the metadata. InputStream is = new BufferedInputStream(new ByteArrayInputStream(imageData)); Image src = null; Iterator<ImageReader> it = ImageIO.getImageReadersByMIMEType(“image/jpeg”); ImageReader reader = it.next(); ImageInputStream iis = … Read more
Although (as I stated in my other answer) the width and height attributes do not interfere with fluid images, fluid images do interfere with not-yet-loaded images taking up the proper amount of space in browsers other than Chrome. There is a workaround for this: wrap the image in a div with an intrinsic ratio, as … Read more
Loading the images on a background thread is still a good idea. If you didn’t want to reload them each time, I’d suggest setting up an NSMutableDictionary and storing the images in there. You could use some unique identifier, like the row ID or even the name of the image, as the key for each … Read more
When to leave the alt attribute empty Typically, the alt attribute is required; however, there are several cases in which the HTML spec says it is OK to leave the alt attribute’s contents empty. The alt attribute is the text equivalent of the image, which means that it should only be empty if the meaning … Read more
You could use the <picture> element to deliver a WebP image to users with browsers that support it, falling back to a JPEG or PNG for those that don’t. The advantage of using the <picture> element rather than other fallback methods is that browsers that don’t support the element will fallback to whatever source is … Read more
function changeImage(a) so there is no such thing as a.src => just use a. demo here
Use ImageReader.getFormatName() You can get the image readers for a file using ImageIO.getImageReaders(Object input). I haven’t tested it myself, but you can try this: ImageInputStream iis = ImageIO.createImageInputStream(file); Iterator<ImageReader> imageReaders = ImageIO.getImageReaders(iis); while (imageReaders.hasNext()) { ImageReader reader = (ImageReader) imageReaders.next(); System.out.printf(“formatName: %s%n”, reader.getFormatName()); }
I had a similar issue when trying to implement it. I use Chrome by default and it was not working. When I tested it in Firefox, it did work. That made me think it was a browser problem. After digging in a bit more, I found out the “problem” for my case. It might be … Read more
You have the filter property: .yourImage{ -webkit-filter: invert(100%); /* Safari/Chrome */ filter: invert(100%); } This will invert the colors as opposed to simply making the image black and white.
If you are using VSCode and you have the module setting in typescript configuration set to ‘es2020’, ‘es2022’, ‘esnext’, ‘system’, ‘node12’, or ‘nodenext’. Then you might want to try simply restarting your typescript server. The quickest way would by hitting (ctrl+shift+p) and selecting restart typescript server. Picture attached.
