Theoretical its simple: convert the picture.jpg into a base64 string and store it with setitem into the localstorage. to display the picture again just load the base64 string from the localstorage and decode back to jpg. But, as always, the practice is more difficult. Im trying to find a way to convert the .jpg files on-the-fly to base64 using html5 or javascript (no php!). Does someone had the same problem and was able to find a

All activity items (including Save Image) work as expected, but when Save Image is tapped, the following error shows in the console, despite the fact that the jpg does actually get saved to the camera roll. Is this a bug in iOS, or do I have to somehow specify that my file is a jpg (and not a video) in the file URL? 2015-07-29 06:46:58.317 AppName[4658:893408] Video /var/mobile/Containers/Data/Application/A63DF08E-21D0

Using Image class we can convert bmp to jpg but the quality of output image is very poor. Can we gain the quality level as good as an image converted to jpg using photoshop with highest quality? 回答1: var qualityEncoder = Encoder.Quality; var quality = (long) ; var ratio = new EncoderParameter(qualityEncoder, quality ); var codecParams = new EncoderParameters(1); codecParams.Param[0] = ratio; var jpegCodecInfo = ; bmp.Save(fileName, jpegCodecInfo, codecParams

当我们使用多个img标签时就会遇到img自带间距的问题如下 解决这个问题很多种方法，下面来简单说一下 1.如果只想解决解决竖向的间距 只需用vertical-align这个属性就可以了 img{ vertical-align: top; } 或者给img标签的父元素加上line-height属性 div{ line-height: 0; } 如果图片很宽一个就占一行的画，比如移动端的长图，给图片加display:block;就可以了； 2.如果只想解决左右的间距问当然可以把四周的间距都取消，然后加margin或者padding，但在网上发行有朋友在img标签左右加上注释包裹，亲测有效果 <img src="./temimage.jpg" alt=""><!-- --><img src="./temimage.jpg" alt=""><!-- --><img src="./temimage.jpg" alt=""><!-- --><img src="./temimage.jpg" alt=""><!-- --><img src="./temimage.jpg" alt=""><!-- --><img src="./temimage.jpg" alt=""><!-- --><img src="./temimage.jpg" alt=""><!-- --><img src=".

网上查了很多图片懒加载的内容, 但基本上都是jQuery实现的, 没有说清楚其原理, 所以研究了一下 多的不说, 上代码, 看不明白的建议看下我的上一篇文章< 1. 图解浏览器和用户设备的宽高等属性 > HTML部分(图片地址自己随意) <div> <img data-src="1.jpg" src="0.gif" alt=""> <img data-src="1.jpg" src="0.gif" alt=""> <img data-src="1.jpg" src="0.gif" alt=""> <img data-src="1.jpg" src="0.gif" alt=""> <img data-src="1.jpg" src="0.gif" alt=""> <img data-src="1.jpg" src="0.gif" alt=""> <img data-src="1.jpg" src="0.gif" alt=""> <img data-src="1.jpg" src="0.gif" alt=""> <img data-src="1.jpg" src="0.gif" alt=""> <img data-src="1.jpg" src="0.gif" alt=""> <img data-src="1.jpg" src="0.gif" alt=""> <img data-src

I used the matplotlib function savefig but when the image is saved, it does not contain anything. It is just a white image.
