How can I create a JavaScript condition to display either image preview of a video or image preview of a picture?

时光毁灭记忆、已成空白 提交于 2020-03-25 16:04:22
问题 On image preview, when I select a video, an empty image box is displayed on the right side of the video image preview. And when I select a picture, an empty space is displayed on the left side of the picture image preview. So both <video> tag and <img> tag are displayed together. Here is the code of the relevant HTML part, which is inside a form tag: <form method="post" enctype="multipart/form-data"> <label class="input-group-prepend" for="image_name"> <i class="fa fa-camera" data-toggle=

Android Camera开发系列:调整Camera预览方向

有时候我们想根据自己的需要调整下Camera的预览方向,那么是调用哪个API可以达到我们的目的呢? 我们看下下图拍的几张小可爱的照片,分别是正常方向、旋转180度、90度拍的照片。 (正常方向) (旋转180度) (旋转90度) 一、Camera API Camera1上,我们可以通过 setDisplayOrientation(int degress); 来设置camera预览的方向。 mCamera.setDisplayOrientation(Surface.ROTATION_180); 这里也贴下源码里面关于setDisplayOrientaion接口的详细说明。 /** * Set the clockwise rotation of preview display in degrees. This affects * the preview frames and the picture displayed after snapshot. This method * is useful for portrait mode applications. Note that preview display of * front-facing cameras is flipped horizontally before the rotation, that * is, the

在uni-app开发中,开发一个资讯详情页面,详情里包含图片和代码块。这时候用简单的rich-text控件已经不够用了。用官方demo里的html-parser.js也无法很好的展示代码区域。这个时候就要使用官方提供的插件来解决。 首先:下载插件: https://ext.dcloud.net.cn/plugin?id=183 第二步:写代码 demo示例 注意:官方提供的示例代码有点小问题,请用我下面的代码。 <template> <div> <u-parse :content="article" @preview="preview" @navigate="navigate" /> </div> </template> <script> import uParse from '../../components/u-parse/u-parse.vue'; //注意:官方提供的示例代码有问题 export default { components: { uParse }, data () { return { article: '<div>我是HTML代码</div>' } }, methods: { preview(src, e) { // do something }, navigate(href, e) { // do something } } } </script>

Cannot select location or pricing tier in FormRecognizer Preview

谁说胖子不能爱 提交于 2020-01-24 01:41:05
问题 I registered for the FormRecognizer public preview and I'm having trouble creating a resource in my Azure environment. I received the welcome email today with the instructions to follow, but when I try to create a FormRecognizer resource in Azure the Location and Pricing dropdowns do not have any selectable options. These fields are required so I cannot create this resource. I have verified that I'm on the Azure subscription that I used to request being part of this Preview Program. Any ideas

问题 After updating Android studio to version 3.1.2 an issue popped up where the preview image is, pixelated/blurry. Can anyone help me fix this issue? This is how the image is rendered 回答1: I have encountered the same problem in Android Studio 3.3 but fortunately I've managed to find a solution.

Once this properties file is made, you will need to write "hidpi=false" (no
