openslide用法 -回复

openslide用法-回复首先，让我们来了解openslide是什么。

OpenSlide是一个开源库，旨在提供一种高效读取大尺寸高分辨率图像的方法。

这种图像通常在数字病理学和其他医学领域中使用，并且可以包含多个尺寸级别和通道。

OpenSlide支持许多常见的图像格式，如SVS、NDPI和TIF。

接下来，我们将逐步介绍如何使用openslide来读取和处理大型高分辨率图像。

第一步是安装OpenSlide库。

可以通过在终端中运行适当的命令来安装OpenSlide。

在Ubuntu上，可以使用以下命令：sudo apt-get install openslide-tools在基于Debian的系统上，可以使用以下命令：sudo yum install openslide-tools对于Windows系统，可以从OpenSlide官方网站上下载适用于Windows 的预编译二进制文件。

安装完成后，我们可以开始使用OpenSlide来读取图像。

第二步是导入OpenSlide库。

在Python中，可以使用以下代码行导入openslide库：import openslide第三步是打开图像文件。

使用`openslide.open()`函数，可以打开图像文件并获取一个OpenSlide对象，如下所示：slide = openslide.OpenSlide("/path/to/image.svs")在此代码中，`"/path/to/image.svs"`应替换为实际图像文件的路径。

第四步是获取图像的基本信息。

可以使用OpenSlide对象的各种属性和方法来获取有关图像的信息，例如图像的尺寸、级别和通道数等。

下面是一些示例代码：# 获取图像的宽度和高度width, height = slide.dimensions# 获取图像的级别数level_count = slide.level_count# 获取图像的通道数channel_count = slide.associated_images.count# 获取指定级别的尺寸level_width, level_height = slide.level_dimensions[level]第五步是读取图像的指定区域。

（NodeMCU开发）篇1：搭建NodeMCU开发环境，HelloWorld

（NodeMCU开发）篇1：搭建NodeMCU开发环境，HelloWorld （NodeMCU开发）篇1：搭建NodeMCU开发环境，HelloWorldCONTENTS前⾔⽬前，关于NodeMCU的开发环境各不⼀样，⽀持在不同平台不同语⾔进⾏开发。

这⾥讲的主要是C语⾔环境的搭建。

同样使⽤C语⾔搭建开发⽅式也有很多，但是本质上都是⼀样的。

在这⾥，收集了各种环境开发⽅式，对其进⾏整理归类，然后选了其中的⼀种综合⽅便与更接近底层的⽅式进⾏开发。

名词解释AiThinkerIDE：安信可 ESP 系列⼀体化开发环境（基于 Windows + Cygwin + Eclipse + GCC 的综合 IDE 环境）。

将window环境封装起来成为⼀个IDE。

<注：在版本的后期将Cygwin换成MSYS2了>GNU兼容环境：这⾥说的GNU环境是指NodeMCU在编译的时需要的编译环境。

有Cygwin、MSYS2。

提供了GUN运⾏环境，能让windows运⾏make命令。

GNU：⼀个技术组织，运动，计划。

—— 软件开源。

GNU/Linux 的意思是上层应⽤程序是GUN体系（遵循GPL标准的⼀套）。

GPL（GeneralPublicLicense）： GUN通⽤公共授权。

编译⼯具链xtensa-lx106-elf：因为ESP8266功能太弱，不⾜以⽀持开发⼯作，所以需要在其他平台上进⾏开发。

现在我们就要在树莓派上将ESP8266的程序代码编译链接成ESP8266可执⾏的⽂件，再将编译好的⽂件烧写到ESP8266上运⾏，这个过程就是交叉编译，交叉编译所需的软件⼯具叫做⼯具链toolchain。

我们需要的⼯具链是⼀个lx106编译器，可以为各种以lx106为内核的器件开发程序，也包括ESP8266。

因为树莓派资源也有限，还有前⾯说过的树莓派操作系统本⾝的问题，我们没有采⽤乐鑫最新的编程架构ESP-IDF。

⽽使⽤较⽼的ESP8266开发⼯具esp-open-sdk为树莓派编译⼀个⼯具链xtensa-lx106-elf。

ios trustkit的用法

ios trustkit的用法TrustKit是Apple开发的一个框架，用于提供安全的网络连接和身份验证。

它提供了一组工具和API，可以帮助开发者在iOS应用程序中实现安全的网络通信和用户身份验证。

本文将介绍TrustKit的用法，包括其核心组件、使用方法以及安全注意事项。

一、TrustKit的核心组件TrustKit主要由以下几个核心组件组成：1.TrustChain：TrustChain是一个基于区块链技术的安全网络信任链，用于跟踪和验证网络通信中各方的可信度。

它提供了一种可验证的信任证明，帮助开发者建立安全的网络连接。

2.JWT（JSONWebToken）：JWT是一种用于身份验证和授权的开放标准，它使用JSON格式来编码信息，并采用数字签名等技术来保证信息的完整性和真实性。

TrustKit提供了对JWT的支持，可以帮助开发者实现用户身份验证。

3.PKCS#12文件：PKCS#12文件是一种用于存储私钥和证书的格式，TrustKit 提供了对PKCS#12文件的读取和写入支持，方便开发者在应用程序中存储和管理密钥和证书。

1.配置TrustKit信任链：在应用程序中配置TrustKit信任链，需要指定一个可信的根证书颁发机构（CA），并允许应用程序访问受信任的证书颁发机构（CA）列表。

这样，TrustKit信任链就可以跟踪网络通信中各方的可信度。

2.使用JWT进行身份验证：TrustKit提供了对JWT的支持，开发者可以使用JWT来进行用户身份验证。

在请求网络资源时，可以将JWT作为请求头或请求参数发送给服务器，服务器使用JWT来验证用户的身份，并根据身份验证结果返回相应的资源。

3.使用PKCS#12文件存储密钥和证书：开发者可以将私钥和证书存储在PKCS#12文件中，并使用TrustKit提供的API读取和写入该文件。

这样，开发者可以在应用程序中安全地管理和使用密钥和证书。

三、安全注意事项在使用TrustKit时，需要注意以下几点以保障应用程序的安全性：1.确保密钥和证书的安全性：密钥和证书应该存储在安全的位置，并设置合适的权限和访问控制，以防止泄露。

Handson Technology ESP8266 NodeMCU WiFi开发板用户手册说明书

User Manual V1.2The ESP8266 is the name of a micro controller designed by Espressif Systems. The ESP8266 itself is a self-contained WiFi networking solution offering as a bridge from existing micro controller to WiFi and is also capable of running self-contained applications. This module comes with a built in USB connector and a rich assortment of pin-outs. With a micro USB cable, you can connect NodeMCU devkit to your laptop and flash it without any trouble, just like Arduino. It is also immediately breadboard friendly.Table of Contents1.

The blue LED at the upper right corner should be blinking every 2 seconds!6. NodeMCU GPIO for LuaThe GPIO(General Purpose Input/Output) allows us to access to pins of ESP8266 , all the pins of ESP8266 accessed using the command GPIO, all the access is based on the I/O index number on the NoddMCU dev kits, not the internal GPIO pin, for example, the pin ‘D7’ on the NodeMCU dev kit is mapped to the internal GPIO pin 13, if you want to turn ‘High’ or ‘Low’ that particular pin you need to called the pin number ‘7’, not the internal GPIO of the pin. When you are programming with generic ESP8266 this confusion will arise which pin needs to be called during programming, if you are using NodeMCU devkit, it has come prepared for working with Lua interpreter which can easily program by looking the pin names associated on the Lua board. If you are using generic ESP8266 device or any other vendor boards please refer to the table below to know which IO index is associated to the internal GPIO of ESP8266.Nodemcu dev kit ESP8266 Pin Nodemcu devkitESP8266 PinD0 GPIO16 D7 GPIO13D1 GPIO5 D8 GPIO15D2 GPIO4 D9 GPIO3D3 GPIO0 D10 GPIO1D4 GPIO2 D11 GPIO9D5 GPIO14 D12 GPIO10D6 GPIO12D0 or GPIO16 can be used only as a read and write pin, no other options like PWM/I2C are supported by this pin.In our example in chapter 5 on blinking the blue LED, the blue LED in connected to GPIO2, it is defined as Pin4 (D4) in Lua script.7.

Check the list of identiﬁedexternal COM ports in the Windows Device Manager and conﬁrm the COM port number ofthe ESP32-DevKitC.2.2.Set Download Mode and SPI Boot ModeAs shown in Figure 1-1, the ESP32-DevKitC features two buttons: one marked as “EN”,which is the reset button and is located on the bottom left corner, and another one marked“Boot” on the bottom right corner, which is the download button.•Download mode:While pressing the “Boot” button, also press the “EN” button to initiate the downloadmode. The system should then enter the download mode and output the following onthe terminal:Figure 2-1. Download Mode Output•SPI boot mode:Simply press the “EN” button and the ESP32-DevKitC will enter the SPI boot mode. Ifdownload operation is completed successfully, the system will output some informationon the terminal, as shown in Figure 2-3.2.3.Download Methodse ESP32 DOWNLOAD TOOLPlease download the latest ESP32 DOWNLOAD TOOL from Espressif website.Open the ESP32 DOWNLOAD TOOL. Select bootloader.bin, paritions_singeapp.bin, andtestje.bin to be downloaded to addresses 0x1000, 0x4000, and 0x10000, respectively.Press “START” and wait for the prompt that indicates the download result.Figure 2-2. ESP32 DOWNLOAD TOOL Interfacee Python ScriptsGet Python scripts from esp-idf/components/esptool_py/esptool/esptool.py in the ESP-IDF.The download process will require the system to have a command terminal. For theWindows System, open the “Windows PowerShell” or “Windows Command Terminal”.On the terminal, set the current directory to where the downloaded Python scripts aresaved, and then type in the following commands:python esptool.py -b 115200 -p COM3 write_flash -ff 40m -fm qio -ih0x0 -il 0x00 0x1000 bootloader.bin 0x4000 partitions_singleapp.bin0x10000 testje.bin2.4.Check the Serial OutputLaunch the serial terminal on the PC and press the “EN” button on the development board. The system is now expected to enter the SPI boot mode and output the following:Figure 2-3. SPI Boot Mode OutputNotes:•The parameters highlighted in blue represent the baud rate, serial port, ﬂash frequency, and the ﬂash mode, respectively. You can change these parameters as necessary.•Only mode is currently supported. Further updates of download tools and scripts will allow support for both the and modes.•To retrieve “help information”, input python esptool.py -h . For information on download commands, input python esptool.py write_flash -h .Disclaimer and Copyright NoticeInformation in this document, including URL references, is subject to change without notice.THIS DOCUMENT IS PROVIDED AS IS WITH NO WARRANTIES WHATSOEVER,INCLUDING ANY WARRANTY OF MERCHANTABILITY , NON-INFRINGEMENT, FITNESS FOR ANY PARTICULAR PURPOSE, OR ANY WARRANTY OTHERWISE ARISING OUT OF ANY PROPOSAL, SPECIFICATION OR SAMPLE.All liability, including liability for infringement of any proprietary rights, relating to the use of information in this document, is disclaimed.

注意事项
1. 连接开发板硬件之前，确保断开所有电源以避免触电危险。

开发板上包含尖锐物体，使用时应当十分小心以避
免意外伤害。

禁止用手指直接触摸开发板裸露金属部分，防止意外扎伤手指。

另外直接触摸金属部分可能导致静电损坏开发板。

未成年人需要在成年人监护下使用此开发板。

2. 开发板天线附近请保持足够的净空区，否则会影响天线性能。

3. 开发板的USB接口与计算机连接时，如果开发板的串口没有被打开，插拔计算机USB外设的操作会造成开发
板复位。

只有使用计算机供电且串口未被打开时会发生此问题，如果使用普通USB电源供电或计算机已经打开串口则不会发生此问题。

4. 开发板的GPIO0上电时若电平为低，则开发板进入烧录固件模式，此时用户的程序将不会被执行。

如果开发板
上电后未能正常工作，请检查如下引脚的电平：GPIO0高，GPIO2高，EN高，RST高，GPIO15低。

若电平不符，请用户检查外围电路并修正。

5. 烧录固件时如果不慎发生中断导致烧录失败，则开发板的程序不完整，此时有一定的可能无法进入自动模式。

此时应当按住FLASH按键不放插入USB线缆，则可正常烧录固件。

6. 如果用户需要使用休眠功能，需要将RST与GPIO16直接连接。

用户可自行连接这两个管脚，或在开发板R3
位置焊接0欧姆的电阻。

注意，使用休眠功能后，GPIO16禁止使用。

7. GPIO16不支持中断、PWM、I2C以及One-wire功能，只能作为普通输入/输出端口使用。

8. 不得对开发板输入超过5V以上的电源电压，也不得将开发板GPIO直接连接到5V电平的外设上。

如果需要连
接，需要电平转换电路，否则可能造成不可逆转的损坏。
