Webcam Capture in C# or VB.NET
Dynamic .NET TWAIN Webcam Module is a C# wrapper for DirectShow webcam capture library. You can use the .NET webcam library to acquire images from any UVC-compatible webcam. With the library, you can access webcam for video preview and image capture in C# or VB.NET easily with simple and intuitive APIs.

Imaging Features
Takes images from DirectShow compatible web cameras.
Saves and upload images to a local disk, FTP site, web server or database.
Supports image formats including BMP, JPEG, PNG,TIFF, and multi-page TIFF.
Provides video container for previewing live video.
Integrates with the .NET TWAIN scanning module for scanning documents from TWAIN compatible scanners.
Integrates with .NET barcode reader and OCR modules for image processing.
Integrates with the PDF add-on to open and save PDF files.
Supports WinForms (.NET 2.0 & 4.0), WPF and Any CPU build.

Save Time and Cost
Intuitive .NET APIs enable you to access DirectShow webcam easily. This saves you time from learning the details of the DirectShow framework. Code samples of interacting with webcams in C# and VB.NET are provided. Award-winning technical support is available to help you deliver a successful solution rapidly.

Dynamsoft's Dynamic .NET TWAIN image capture SDK has an integrate barcode add-on that allows you to retrieve barcode information from documents and images captured from scanners, webcams and other devices. It also provides a barcode generator API which allows creating barcodes in scanned documents and captured images. Developers can easily recognize linear barcodes, QR code, PDF417 and DataMatrix in C# and VB.NET applications.

SamplesDynamic .NET TWAIN is suitable for developing a Windows Forms or WPF application. Powered by its own barcode library add-on, users can read barcodes from existing image files or scanners and webcams. Below are some samples for developers to get started.

View and Convert PDFs to Images in C# or VB.NET

Dynamsoft PDF Library allows you to convert vector PDF documents to raster images (JPEG, PNG, TIFF, PDF) for easier viewing or sharing in just a couple of lines of code in C# or VB.NET.

Add PDF Annotations in C# / VB.NET; Add-on to Dynamic .NET TWAINThe PDF Annotation add-on of Dynamic .NET TWAIN enables you to add PDF annotation functionality to your WinForms applications in C# or VB.NET. This allows for markup and objects to be superimposed directly onto a PDF document, without changing the underlying master PDF. Annotations include underlines or highlights, notes and comments, circles, rectangles, and more.

Saves all images in buffer as a multi-page PDF file.
Saves all images in buffer as a multi-page PDF byte array.
Sets various properties and metadata on PDF creation, including author, creator, producer, creation date, modified date, margin, page size, keywords, subject, title, compression type, and version.
Encrypt a PDF file with password and permissions and save the result as a new PDF file.
Merges several specified PDF files on disk into a new file.
Uploads images in the buffer as a multi-page PDF file via FTP and HTTP.

High-speed viewing of PDF documents in your WinForms or WPF applications.
Customize the resolution when rasterizing PDF documents.
Convert PDF documents into popular image formats, including JPEG, TIFF, PDF files, PNG, and BMP. Multi-page TIFF and PDF are also supported.
Supports CCITT G3/G4, JPEG, Flate, LZW, RLE and ZIP embedded images.
Supports reading PDF/A images.
Supports all font types: Type0, Type1, Type1C, Type3 and TrueType.
Supports all three text rendering modes (full, stroke, clipping).
Supports all colorspaces: RGB, Gray, CMYK, ICCBased, Lab, Indexed, Separation, DeviceN and Pattern.

Set the order of annotations by using "pull to front" and "push to back".
Allow any object to be rendered at transparency levels from 0 - 100%.
Add any number of annotation objects to an image. These objects can be moved and resized independently.
Multiple annotations can be selected as a group so that they are moved as one object.
Annotations can be printed with the base image.
Text annotations can be rotated with the image in 90 degree increments.
A smooth dynamic display. Objects are shown with an outline when resizing, so the resulting size is clear.
Responds to numerous mouse clicks events, allowing custom scripts or actions to be implemented.
Annotations can use custom controls by making use of the Annotation Data class.
All icons for all annotation types are fully customizable at any size.
