我有名为 frameBytes 的 Uint8Array。我已经用这段代码从这个字节数组中创建了 RGBA 值。

    for (var i = 0; i < frameBytes.length; i++) {
        imgData.data[4 * i] = frameBytes[i];// red
        imgData.data[4 * i + 1] = frameBytes[i]; // green
        imgData.data[4 * i + 2] = frameBytes[i];// blue
        imgData.data[4 * i + 3] = 255; // alpha 
    }

然后我使用以下代码将此 GRBA 值显示到画布上。

var ctx = fingerFrame.getContext('2d');
var imgData = ctx.createImageData(fingerFrame.width, fingerFrame.height);
ctx.putImageData(imgData, 0, 0, 0, 0, fingerFrame.width, fingerFrame.height);

在那之后，我曾经使用以下代码在画布中对图像标记进行图像处理：

 const img = document.getElementById('i');  
 img.src = fingerFrame.toDataURL(); 

但我不想使用画布。我想直接在 Uint8Array 的图像标签中显示图像。我怎样才能做到这一点？任何帮助将不胜感激。

我到了java.lang.NullPointerException.我在app level gradle中更改了build.gradle.我的build .gradle如下:

apply plugin: 'com.android.application'

我想将一个int列表从C#传递给一个用vb6编写的dll.在vb6中,函数的原型如下:

Public Function FamIdentify(agentList As Collection, strName As String, strIdentifyTemplate As String, strIP As String) As Boolean

从C#我调用这个函数如下:

public Boolean IdentifyFinger(String name, String SampleModel, String REMOTE_ADDR) 
{ 
List<int> agentList = new List<int>(); 
// insert some element to this list
FamServer.FamApp famApp = new FamServer.FamApp(); 
Boolean flag = famApp.FamIdentify(ref agentList, ref name, SampleModel, REMOTE_ADDR);
 return flag ; 
}

对于这种编码,我面临这个错误

cannot convert from system.collections.generic.list to string to Vba.collections

如何将列表从C#传递给vb6？请帮我 .

我有一个简单的php脚本：

<?php


            $DB = '//10.11.201.170:1521/XE';
            $DB_USER = 'BIOTPL';
            $DB_PASS = 'biotpl';
            $DB_CHAR = 'AL32UTF8';

            $conn = oci_connect($DB_USER, $DB_PASS, $DB, $DB_CHAR);
            if($conn)
            {
                echo "Successfully connected to Oracle.\n";
                OCILogoff($c);
                //$statement = oci_parse($conn, 'select 1 from dual');
                //oci_execute($statement);
                //$row = oci_fetch_array($statement, OCI_ASSOC+OCI_RETURN_NULLS);
            }
            else
            {
                $err = OCIError();
                echo "Connection failed." . $err[text];
            }  
?>

当我运行它（从浏览器或命令行）时，出现错误：

Call to undefined function oci_connect

我正在使用php 5.6.24。我已经将php_oci8.dll和php_oci8_11g.dll复制到/ ext文件夹中。我有

extension=php_oci8.dll 
extension=php_oci8_11g.dll  

在我的php.ini中，我已经安装了即时client_11_2-尝试了32位版本。我有ORACLE_HOME和TNS_ADMIN环境变量指向即时客户端文件夹（C：\ instantclient_11_2）。

我花了数小时的时间来尝试不同的事情，但无济于事。

我已经安装了Microsoft Visual C ++ 2010运行时（x86）。OCI8扩展需要此功能。我已经安装了Microsoft Visual C ++ 2012 Runtime（x86）。PHP需要此功能。

当我尝试以下命令时：

我想减少bootstrap 4模态默认的height和width。为此，我编写了以下代码：

<div class="modal-header" style="background-color: darkblue;color:#fff;height:5%;!important">
  <p class="mx-auto d-block">Please Give Your Finger</p>  
</div>

我已将模式标题的高度设置为5％。但高度与默认值相同。如何降低引导程序模态头的高度？

I have a String array in java as follows.

String[] text = {"hello", "bye"};

Now I need to use Java stream API to calculate the length of each string in this array. I do not want to use for loop. How can I do that?

Update: I have checked this link and got the following code to get the sum of the length of each string of this array.

Arrays.stream(text)
      .filter(Objects::nonNull)
      .mapToInt(String::length)
      .reduce(0,Integer::sum);
