We are pleased to announce that Dynamic Web TWAIN 12.0 is now available!

Highlights of the new version:

• [HTML5 Only] Added a new method HTTPUpload which supports uploading files as binary as well as base64 string. The method also supports segmented upload when handling big files.
• [HTML5 Only] Added a new method ConvertToBase64 which supports converting one or more images to a base64 string.
• [HTML5 Only] Added a new method SetHTTPHeader which supports adding a header to an HTTP Upload Post request.
• [HTML5 Only] Added a new method GetImageURL which returns the direct URL of an image based on its index in the buffer.
• Added a new property IfAutoScroll which when set to false will stop the automatic scrolling of the viewer when scanning or loading images.
• Added a new security feature called Dynamsoft Authentication which requires more user interaction when dealing with local files or devices.
• Added MSI installers for both ActiveX and HTML5 editions.

• Improved the method ChangeImageSize by adding a new mechanism for the new option "Best Quality".
• Improved the way license verification is done and optimized the error messages for license issues.
• Improved the way a Web TWAIN object is created by adding global methods like Dynamsoft.WebTwainEnv.CreateDWTObject and Dynamsoft.WebTwainEnv.DeleteDWTObject.
• Improved the image editor's zooming feature by allowing it to zoom centered by the position of the mouse.
• Fixed a bug where MagData doesn't work during scanning.
• Fixed a bug with the Mac edition where TIFF files are loaded with inverted colors.
• Fixed a bug where the event OnPostLoad gets triggered twice when loading a file.
• Fixed a bug with the ActiveX where selecting an image area returns the wrong coordinates when the image is bigger than the viewer (scrollbars are shown).
• Fixed a bug where CurrentImageIndexInBuffer and HowManyImagesInBuffer are not updated correctly when the method LoadImagesFromBase64Binary is used.
• Other minor fixes and tweaks.
