What this article shares with you is about how Dynamic Web TWAIN can obtain dynamic Web TWAIN SDK. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

Dynamic Web TWAIN is a TWAIN scan recognition control designed specifically for Web applications. You only need to write a few lines of code in the TWAIN interface to scan documents with TWAIN-compatible scanners or get images from digital cameras / capture cards. The user can then edit the image and save the image in a variety of formats, and the user can save the image to a remote database or SharePoint. The TWAIN control also supports uploading and processing local images. Here are some common questions about Dynamic Web TWAIN programming and answers to them.

Option 1: download the 30-day free trial version

Online download link

Note:

You can download .exe for Windows or .tar.gz for Linux or .dmg.zip for macOS. A 30-day free trial key is automatically generated for .exe and .dmg.zip. For Linux, however, you will need to manually request the trial key online and update the key yourself.

Option 2: download the Dynamic Web TWAIN package package from the Node package Manager. You can download it like this

Npm install dwt@15.0

Note:

Files downloaded through npm do not contain binaries, such as the Dynamsoft Service installer. Instead, these files are deployed on Dynamsoft's Server and configured to be downloaded when running the examples that come with the package. In addition, the trial key used by the package may not be valid when you download it. In this case, you can request the trial key online and update the key yourself.

Full version

Option 1: download the complete package when you purchase

When you purchase a license, Dynamsoft will send you an email containing the license key and a download link for the full installer.

Note:

All samples, resource files, etc. included with the full installer do not contain any licenses. You can apply for a license according to this article.

Option 2: use NPM

Because the node package manager is open to the public, Dynamsoft does not put the full version of the package here. This means that running the following command will always download only the trial version.

Npm install dwt@15.0

In order to use the full version, developers must make some custom configurations in their JavaScript / TypeScript code:

Dynamsoft.WebTwainEnv.Trial = false;Dynamsoft.WebTwainEnv.ProductKey = "{the full version key}"; Dynamsoft.WebTwainEnv.ResourcesPath = "{the relative or absolute path to the libraries}"

Note:

By default, only trial libraries are provided when dynamsoft.webtwain.min.js,ResourcesPath is set to "https://tst.dynamsoft.com/libs/dwt/15.0" in this file. After purchase, you will have a complete version library, which you need to put on the server and change the path in the application accordingly.

The above is how Dynamic Web TWAIN can obtain dynamic Web TWAIN SDK, and the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
